	* gcccompat/galloca.c: Bug 174 Fix. If GCC determines
	that a call to __gcc_alloca can never be reached, it will
	optimise it away. However, __gcc_alloca_restore is still
	called and crashes because a block was never allocated.
	Fix by exiting if a chunk isn't found.

Thu Nov 26 10:13:45 PST 2009  Peter Naulls  <peter@chocky.org>

	* time/ctime.c, time/stdtime.c, time/asctime.c, include/time.h,
	  incl-local/time.h: Add asctime_r, ctime_r.

Sat Nov 14 10:30:39 PST 2009  Peter Naulls  <peter@chocky.org>

	* string/_strlen.s: Alignment access fix from Adrian
          Lees (Bug #173).

Wed Oct 21 17:46:48 2009  Lee Noar  <leenoar@sky.com>

	* incl-local/internal/unix.h(struct __process): Add
	2 new flags to record how this process was created.
	* sys/exec.c(execve): Set flag to show that this
	process was the result of exec().
	* sys/vfork.c(__fork_post): Set flag to show that this
	process was the result of fork().
	* unix/unix.c(_exit): Be more careful about when we
	deregister the client from the Shared Object Manager.
	A process that was forked (but not execed) is
	considered to be the same client as its parent. It
	should not be deregistered on exit, so that control can
	be successfully returned to the parent.
	A process that was execed (even if forked) is a new client
	in its own right and distinct from its parent and should
	be deregistered on exit.
	A process with no parent should always be deregistered.

Sat Sep 19 12:41:12 2009  Lee Noar  <leenoar@sky.com>

	* gmon/gmon_start.c: Don't use _init symbol to find the
	start of the text segment as this creates a bogus
	DT_INIT entry in the dynamic segment. Instead use the
	linker generated __text_start.

Mon Aug 24 10:41:22 PDT 2009  Peter Naulls  <peter@chocky.org>

	* signal/post.c: Skip over # at start of C++ symbol names
        for demangling.
	* sys/_syslib.s: Typo fix.
	* pthread/_yield.s: Register handling safety from John Tytgat.
        * debug/dvsprintf.c: Use stdio for __os_printf after stdio
        is initialised, otherwise Wimp debugging can become very
        difficult.

Thu Aug 20 00:44:36 CEST 2009  John Tytgat  <John.Tytgat@aaug.net>

	* incl-local/pthread.h(__pthread_saved_context): don't define fpregs
	and fpstatus in softfloat builds.

Sun Aug 16 12:58:06 PDT 2009   Peter Naulls  <peter@chocky.org>

	* sys/mman.c: Simplistic mmap file handling. Only supports reading
        from a zero offset, but this covers much of its use.

Sun Aug  9 01:15:13 CEST 2009  John Tytgat  <John.Tytgat@aaug.net>

	* netlib/getnameinfo.c: Removed, we have another implementation in
	netlib/getaddrinfo.c.

Sun Aug  2 07:44:06 PDT 2009  Peter Naulls  <peter@chocky.org>

	* sys/errlist.c: Add entry for EOVERFLOW.
	* libm-dbl64/s_finite.c, libm-dbl64/s_isinf.c, libm-dbl64/s_isnan.c,
          libm-flt32/s_isinff.c, libm-flt32/s_finitef.c libm-flt32/s_isnanf.c:
	Remove hidden_def, since it seems to serve no purpose, and 
        causes linking errors.

Fri Jul 31 14:20:29 PDT 2009  Peter Naulls  <peter@chocky.org>

	* include/errno.h: Add EOVERFLOW.  Not used by UnixLib,
          but sometimes returned by library routines.

Thu Jul 16 17:29:12 2009  Lee Noar  <leenoar@sky.com>

	* Generally:
	Implement very simple profiling. Only function call
	counting is supported, there is no timing. Only really
	effective on statically linked code. Some of this
	code is imported and adapted from glibc.

	* Specifically:
	* include/sys/gmon.h: New file. Standard header for
	profiling support.
	* include/sys/gmon_out.h: Likewise.
	* gmon/gmon.c: New file. Support routines for profiling.
	* gmon/prof-freq.c: New file. Stub implementation of
	__profile_frequency().
	* gmon/mcount.c: New file. Simple mcount implementation
	that counts function calls and records their relationships.
	* gmon/gmon-start.c: New file. Code called at program startup
	to start profiling. Also registers function with atexit to
	write results to file.
	* incl-local/internal/machine-gmon.h: New file. mcount
	machine code stub that saves any registers that real mcount
	code would otherwise corrupt.
	* incl-local/internal/unix.h(ul_global): Add word to record
	flags passed by (g)crt1-riscos.o.
	* incl-local/internal/asm_dec.s: Add constant for above.
	* incl-local/sys/cdefs.h: Define some of the symbol attribute
	macros.
	* sys/_syslib.s(__main): Call __gmon_start__ if profiling is
	enabled.

Fri Jul 03 19:42:48 2009  Lee Noar  <leenoar@sky.com>

	* sys/exec.c(execve): Only deregister the client from the
	Shared Object Manager if we are not the parent of another
	process. If the client is a parent, then it must remain
	registered so that the child can return.
	Also don't bother about accessing global variables after
	deregistering. Examination of the compiled code shows that
	despite attempts to ensure that this doesn't happen, the
	compiler still generates accesses to global variables after
	deregistering without any ill effects. In fact, there should
	be no ill effects as the PIC register and R/W data segment are
	still valid and are not under the control of the Shared
	Object Manager.

Mon Jun 22 19:23:05 2009  Lee Noar  <leenoar@sky.com>

	* gcccompat/_eh_support.s: Add PIC instructions.
	* gcccompat/_b_return.s: Likewise.

Sun Jun 14 14:46:12 2009  Lee Noar  <leenoar@sky.com>

	* gcccompat/_eh_support.s:
	* (__ehs_stack_limit): New function.
	Given a stack pointer (which will not be the current one),
	determine which stack chunk contains it and return the stack
	limit for that chunk. Used by uw_install_context() in
	unwind-dw2.c (call frame exception handling). The stack
	unwinder steps through the call frames looking for either
	cleanup handlers or exception handlers. The context is installed
	once one of these is found, however, the frame that is jumped
	to may be within a different stack chunk so we have to restore
	the stack limit for that chunk.
	* (__ehs_trim_stack): New function.
	Wrapper for __trim_stack to preserve any registers that it may
	use/corrupt. If the stack unwinder unwinds down the call frames
	to a different stack chunk, then there will be one or more
	redundant chunks that need to be freed.

Sun Jun 7 11:10:43 2009  Lee Noar  <leenoar@sky.com>

	* General overview:
	The call frame C++ exception handling code creates a table of
	call frames that relate to the frames on the stack. This table
	allows the stack unwinder to maintain a context that stores
	the locations of all registers stored by the current function
	on entry.
	The return address of a function is used as a key to allow the
	stack unwinder to find its particular entry in the table. If the
	wrong return address is used, then exception handling will fail
	usually with a crash in the personality routine. The personality
	routine (for C++ at least) attempts to write to r0 and r1 in the
	stack frame. These registers aren't usually saved on function
	entry, only a few exception handling functions actually save
	these registers.
	Wesnoth is an example of where these crashes have been observed.

	* Specifically:
	* gcccompat/_b_frame.s(__builtin_frame_address): I have found
	that __builtin_frame_address can return the wrong result under
	certain circumstances, e.g., when the requested fp is not within
	the current stack chunk. This causes __builtin_return_address to
	give the wrong return address and crashes in C++ exception
	handling as detailed above. The problem seems to be that the
	behaviour of the SCL is slightly different to UnixLib when the
	stack is extended. UnixLib creates a new chunk and starts using
	that as the stack, but the comment in the code suggests that SCL
	copies a frame as well. I believe that this makes the chain of
	frames slightly different for UnixLib and SCL. These changes
	simplify the UnixLib code to match the stack extension code, but
	leave the SCL code as is, as I have no reason to believe that it
	is wrong in this case.
	* gcccompat/_b_return.s(__builtin_return_address): UnixLib code
	attempts to load the return address from the stack chunk which is
	addressed by a2. However, at this point, a2 will either contain a
	frame address or have been corrupted by the call to
	__gcc_alloca_return_address() leading to crashes in exception
	handling as detailed above.
	Set a2 to contain the address of the current stack chunk. Note
	that using the chunk that actually contains the requested fp
	doesn't work as far as exception handling is concerned.
	* gcccompat/_eh_support.s(__ehs_return_address): New file, new
	function. The context maintained by the exception handling code,
	as detailed above, is initialised from the call frame table using
	a return address obtained via __builtin_return_address(). This
	correctly handles the case whereby the return address may be
	__free_stack_chunk or __gcc_alloca_free. However, further updates
	to the context by the stack unwinder retrieve the return address
	directly from the stack. If the return address happens to be one
	of these functions, then exception handling will fail.
	__ehs_return_address() does a similar job to
	__builtin_return_address() in that it traps these special functions
	and returns the correct result. It differs in that we already know
	the frame address (which will not be the current one) and are able
	to pass it as an argument.

Wed May 27 20:31:18 PDT 2009  Peter Naulls  <peter@chocky.org>

	* sys/byteorder.h: Fix bogus include.  Seems to have been wrong
	for a long time.

Sat May 23 15:29:42 CET 2009  John Tytgat  <John.Tytgat@aaug.net>

	* unix/getenv.c(__last_environ): Removed, is now
	__ul_global.last_environ.
	* incl-local/internal/unix.h(struct ul_global): Replaced __notused5
	by last_environ field, always have a main function pointer.
	(_main): Removed prototype, no longer exists.
	* unix/setenv.c(unsetenv): Micro optimisation.
	(clearenv): Make use of last_environ from __ul_global.
	* unix/putenv.c(__addenv_to_env): Likewise.
	* unix/unix.c(_main, main prototype): Remove, equivalent code got
	added to __main.
	* incl-local/internal/asm_dec.s(PROC_ARGC,PROC_ARGV): Added.
	(GBL_*): Fixes up some recently allocated entries.
	(GBL_LASTENVIRON): Added.
	* sys/_syslib.s(__main): Instead of calling _main, call user
	supplied main routine directly.
	(main): Have it always defined.
	* vscript(__last_environ): Removed.
	* local/ctypetable.c(__build_ctype_tables): Fix comment.
	* test/env/testenv.c: Dump environ.

Thu May 21 18:58:32 2009  Lee Noar  <leenoar@sky.com>

	* sys/exec.c(execve): Deregister the current client from the
	Shared Object Manager before passing control to the new
	process. Fix for bug 171.

Mon May 11 23:31:29 CET 2009  John Tytgat  <John.Tytgat@aaug.net>

	* include/bits/posix_opt.h(_POSIX_TIMEOUTS): Disabled as we don't
	have pthread_mutex_timedlock.

Sat Mar 28 14:36:21 CET 2009  John Tytgat  <John.Tytgat@aaug.net>

	* include/kernel.h: Constify _kernel_osfind name parameter;
	'unsigned' -> 'unsigned int'.
	* scl/_kosfind.s: Update comments.
	* sys/mman.c: White space change.

Sat Mar 28 11:30:10 2009  Lee Noar  <leenoar@sky.com>

	* signal/_signal.s(__h_error): Make sure a valid signal number
	is passed to __unixlib_raise_signal() when __SOFTFP__ is defined.
	Previously, for example, instead of seeing a branch through zero
	error, you would get a recursive signal because the signal handler
	itself would cause a memory violation due to a2 containing a
	pointer instead of an array index.

Sun Jan 18 19:45:02 2009  Lee Noar  <leenoar@sky.com>

	* incl-local/internal/unix.h(__funcall): In the shared library,
	function addresses can and will exist outside application space,
	so don't test against appspace_himem.
	* unixlib/buildoptions.h: Remove comment.

Sun Jan 18 16:57:12 2009  Lee Noar  <leenoar@sky.com>

	* Generally:
	Implement lstat so that symlinks can be probed. Fix for
	bug(feature request) #162 item 1.

	stat() - Always follow symlinks and return info on target object.
	lstat() - Do not follow symlinks, and return info on given
	object even if symlink. As per Linux, if a symlink is lstat()ed,
	S_IFLNK = TRUE, S_IFREG = FALSE.

	* Specifically:
	* unix/custom.c: Add __customlstat().
	* unix/lstat.c(lstat,lstat64): Call new implementation instead
	of stat().
	* unix/dev.c: Add __fslstat() and ensure all devices have a
	suitable lstat entry.
	* common/objattr.c(__object_get_lattrs): New function similar
	to __object_get_attrs() except symlinks are not followed. Allows
	the file info of the symlink itself to be found.
	* common/symlinks.c: Move macro definitions of constants...
	* incl-local/internal/symlinks.h: ...to here.
	* incl-local/internal/local.h: Add declaration of
	__object_get_lattrs().
	* incl-local/internal/dev.h: Add lstat entry to struct dev.
	Add declarations for __fslstat() and __customlstat().
	* incl-local/internal/unix.h: Instead of declaring
	__resolve_symlinks() directly, include symlinks.h.

Sat Jan 17 20:10:49 2009  Lee Noar  <leenoar@sky.com>

	* common/objattr.c(__object_set_attrs): Fix typo that would lead
	to a memory leak.

Sat Jan 17 18:22:26 CET 2009  John Tytgat  <John.Tytgat@aaug.net>

	* unix/unix.c(convert_command_line): Reverting r1904 change
	(Fri Mar 10 21:25:47 2006) and canonicalise using Run$Path; When
	result of canonicalisation is non-existing, use given argv[0] as
	input for unixify; Made	common fatal exit point; void return instead
	of unused int return.

Sat Jan 17 15:53:04 CET 2009  John Tytgat  <John.Tytgat@aaug.net>

	* include/kernel.h: Add 'int' to 'unsigned'.
	* README(Building): Updated.

Fri Jan 16 02:53:30 CET 2009  John Tytgat  <John.Tytgat@aaug.net>

	*  unix/features.c(__get_program_name): A colum character can mark the
	start of a leafname as well.  Solves Bugzilla #169 (reported by John
	Kortink).

Sat Jan  3 21:03:34 CET 2009  John Tytgat  <John.Tytgat@aaug.net>

	* ChangeLog: Updated John-Mark Bell's e-mail address.

Fri Jan  2 03:23:07 CET 2009  John Tytgat  <John.Tytgat@aaug.net>

	* module/sul.s: Update module title with "(debug)" string when
	DEBUG_PROC_MATCHING has been defined.

-----------------------------------------------------------------------
[ UnixLib v5.0 ]

Fri Jan  2 03:09:47 CET 2009  John Tytgat  <John.Tytgat@aaug.net>

	* stdlib/msort.c: Fixed wrong __mempcpy emulation (when result gets
	written back to first __mempcpy argument).

Tue Dec 23 02:25:46 CET 2008  John Tytgat  <John.Tytgat@aaug.net>

	* test/env/testenv.c: Added test for inheritance of environment
	variables from parent to child process and when changes from
	Unix environment variables need to result in updated RISC OS
	system variables.  Based on a test program written and posted
	in ML by Peter Naulls.

Sat Dec 20 14:34:20 CET 2008  Theo Markettos <theo@markettos.org.uk>

	* grp/getgrouplist.c(getgrouplist): Added.
	* test/grp/getgrouplist.c,test/grp/test.group: Added test application
	for getgrouplist code.
	* include/grp.h(getgrouplist): Added prototype.

Thu Dec 18 22:57:28 CET 2008  John Tytgat  <John.Tytgat@aaug.net>

	* unix/syslog.c(vsyslog): More sensible mapping between Unix and
	RISC OS syslog priorities.

Thu Dec 18 22:23:52 CET 2008  John Tytgat  <John.Tytgat@aaug.net>

	* stdlib/msort.c: Copy from glibc 2.9 which has a much better qsort
	implementation.  Number of compares done in testsort2.c dropped from
	1849086/1534480/834012928/627343953 to 1536347/815024/853904/1209216.
	* stdlib/memcopy.h: Added, also from glibc 2.9.
	* stdlib/qsort.c: Removed.
	* test/stdlib/testsort2.c: Added.

Mon Dec 15 05:08:52 CET 2008  John Tytgat  <John.Tytgat@aaug.net>

	* unix/features.c(features): Implement coredump feature.
	* signal/post.c(__write_backtrace): Mark as pthread unsafe.
	(post_signal): Move FPE reg dump code to __write_backtrace; call
	__unixlib_write_coredump when action is 'core'.
	* include/unixlib/local.h(__unixlib_write_coredump,__write_backtrack):
	Make public.
	* vscript(__backtrace_getfp): Remove, this routine no longer exists.
	* README: Document 'coredump' feature.
	* incl-local/internal/sigstate.h(__init_coredump): Add prototype.
	* incl-local/internal/swiparams.h(OSFILE_SAVEBLOCK_LOADNEXEC,
	OSFILE_SAVEBLOCK_FILETYPE): Define.
	* sys/_os.s(__os_file): Don't change a3 when it was 0 on entry.
	* sys/mman.c(__init_coredump): Define coredump directory.
	(__unixlib_write_coredump): Write coredump files (application space
	and all DAs).

Tue Dec  2 02:36:59 CET 2008  John Tytgat  <John.Tytgat@aaug.net>

	* test/pthread/fork.c(__UNIXLIB_INTERNALS): Remove usage as it is no
	longer needed.
	* include/complex.h: Likewise.
	* include/features.h: Likewise.
	* include/math.h: Likewise.
	* include/sys/cdefs.h: Likewise.
	* incl-local/internal/fd.h: Likewise.
	* incl-local/internal/os.h: Likewise.
	* incl-local/internal/unix.h: Likewise.
	* incl-local/internal/swiparams.h: Likewise.
	* gen-auto.pl(AM_CFLAGS): Remove __UNIXLIB_INTERNALS definition and
	add __GNU_LIBRARY__ and __NO_LONG_DOUBLE_MATH definitions.

Fri Oct 24 02:07:18 CEST 2008  John Tytgat  <John.Tytgat@aaug.net>

	* string/strdup.c(strdup): renamed strdup to __strdup and
	provided weak alias strdup instead.

Mon Oct 13 02:34:22 CEST 2008  John Tytgat  <John.Tytgat@aaug.net>

	* pthread/_exit.s(__pthread_exit): Simplify code.

Mon Oct 13 02:19:00 CEST 2008  John Tytgat  <John.Tytgat@aaug.net>

	* gen-auto.pl: Fix typo.

Tue Sep  9 19:29:39 PDT 2008  Peter Naulls  <peter@chocky.org>

	* pthread/cond.c(pthread_cond_timedwait): Fix divisor.
	Timeout is in centiseconds, not milliseconds.

Tue Sep  9 20:49:05 2008  Lee Noar  <leenoar@sky.com>

	* signal/post.c(sigsetup): Don't use the address range of the
	application to validate the location of the signal handler when
	compiling for the shared library.

Thu Aug 28 20:27:45 2008  Lee Noar  <leenoar@sky.com>

	* pthread/_yields.s(pthread_yield): The current implementation
	uses a single STMDB instruction to store all relevant registers
	to __cbreg including two banked registers. Under certain
	circumstances, this can trigger a bug in revision K StrongARM
	CPUs whereby the banked register r14 is not saved. To overcome
	the bug, split the instruction into two STMs so that the banked
	registers are saved independently of the others.

Mon Aug 11 20:38:14 2008  Lee Noar  <leenoar@sky.com>

	* signal/_signal.s(__h_cback): Make sure __pthread_callback
	is called with r7 containing the UnixLib GOT pointer as it
	expects.

Wed Aug  6 20:34:09 2008  Lee Noar  <leenoar@sky.com>

	* pthread/cancel.c: Add dummy function that is never called or
	referenced. Its only purpose is to ensure that several pthread
	functions that are made weak in libstdc++ are pulled in by the
	static linker which otherwise would resolve to NULL. This only
	effects statically linked C++ binaries.

Sun Jul  6 17:12:39 PDT 2008  Peter Naulls  <peter@chocky.org>

	* common/riscosify.c: Add defines for a cut-down version of
	__riscosify for the benefit libdl, which only needs to handle a single 
	case.  This doesn't change the behaviour of the code for UnixLib or
	SCL.

Fri Jun 13 01:33:48 CEST 2008  John Tytgat  <John.Tytgat@aaug.net>

	* include/bits/netdb.h(_sclose,_sread,_swrite,_sioctl): Move internal

	* string/stricmp.c(strcasecmp): Make strcasecmp strong alias of
	stricmp.

	strnicmp.
	* string/memcmp.c(bcmp): Make bcmp strong alias of memcmp.
	* string/memrchr.c: Go for original glibc 2.7 version.
	* string/strchrnul.c: Likewise.

Fri May 16 01:43:59 CEST 2008  John Tytgat  <John.Tytgat@aaug.net>

	* common/symlinks.c(__resolve_symlinks): avoid writing to NULL.

Tue May 13 21:07:51 CEST 2008  John Tytgat  <John.Tytgat@aaug.net>

	* unix/dev.c(__fsopen): Call __riscosify only once as the result of
	__resolve_symlinks is guaranteed to be already a RISC OS filename.
	* common/symlinks.c(__resolve_symlinks): avoid malloc/free sequence
	unless it is really necessary and reuse previously claimed buffer when
	possible; Made code a little bit more compact; Added comments.

Thu May  1 20:08:23 PDT 2008  Peter Naulls  <peter@chocky.org>

	* pthread/lock.c: Fix logic from earlier tidy.

Wed Apr 23 22:23:03 PDT 2008  Peter Naulls  <peter@chocky.org>

	* unix/custom.c, include/unixlib/local.h: New function to 
	  allow opaque setting of custom select() function.

Sun Apr  6 01:47:47 CEST 2008  John Tytgat  <John.Tytgat@aaug.net>

	* include/pthread.h(struct __pthread_thread,
	__pthread_running_thread): Move to...

	* debug/debug.c(__debug): Added a bit more debug info.

Sun Mar 30 15:33:22 CEST 2008  John Tytgat  <John.Tytgat@aaug.net>

	* test/process-redirect/{child.c,Makefile,parent.c,RunTestQueue,feb}:
	Added test suite used to test the recent redirection/pipe/dup fixes.

Sat Mar 29 18:48:49 CET 2008  John Tytgat  <John.Tytgat@aaug.net>

	* unix/fcntl.c(fcntl): Case F_DUPFD needs file descriptors to be
	copied too otherwise we would be closing OS_ChangeRedirection acquired
	RISC OS handles (FILE_HANDLE_FROM_OS).  And FILE_ISDIR bit also needs
	to be copied.
	* include/unixlib/unix.h(struct ul_global): Renamed __unused1,
	__unused4 and __unused2 to rewindpipeoffset, changeredir0 and
	changeredir1.
	* sys/_syslib.s: Likewise.

	based on file descriptors 0 and 1 when those are real files or a pipe.
	Also record the read pipe offset for file descriptor 1 as
	rewindpipeoffset and move file offset to the end. Any non-UL process
	(e.g. libscl, OS command) can now read/write data using file handles
	managed by parent.

Thu Mar 27 02:24:59 CET 2008  John Tytgat  <John.Tytgat@aaug.net>

	* vscript(_Exit,__exit,__exit_no_code,__exit_with_error_block):

	* time/gettod.c(gettimeofday): Simplified code for tz != NULL.
	* time/mktime.c(mktime): calculated tm_wday and tm_yday fields were
	one off.
	* time/clk_gettime.c(clock_gettime): case CLOCK_REALTIME: use uint64_t
	based calculation which now gives correct result; case
	CLOCK_MONOTONIC: calculated tv_nsec field was 100 times too big.

Fri Mar 21 13:26:13 CET 2008  John Tytgat  <John.Tytgat@aaug.net>

	* serial/common.c(__get_file_ino): combining directory and filename
	should be done with a Unix directory separator, not RISC OS one;
	some variable shuffling resulting in dropping a nasty cast.

	* README: Added comment on Wimp_StartTask usage in threaded programs.
	Updated description on build options.

Sat Feb 16 07:05:37 PST 2008  Peter Naulls  <peter@chocky.org>

	* include/stdio.h, stdio/putc.c: Change putc_unlocked to a
	declaration. This works better with some code that gets confused when
	it's a #define.
	* unix/setenv.c, unix/putenv.c: Make putenv works as advertised for
	setenv when handling RISC OS native variables as documented in the
	README.

Tue Jan 29 22:46:43 PST 2008  Peter Naulls  <peter@chocky.org>

	a bss section whose size is not a multiple of 4 is merged before this one,
	then it will be misaligned.
	* sys/_vfork.s: Likewise.

Thu Dec 27 04:47:04 CET 2007  John Tytgat  <John.Tytgat@aaug.net>

	* sys/_jmp.s (setjmp): Previous change introduced wrong GOT handling
	for shared library support.

	sys/execvp.c: Make use of debug_printf.

Sat Nov 10 18:06:26 CET 2007  John Tytgat  <John.Tytgat@aaug.net>

	* common/riscosify.c: Use GNU code style
	(__sfixfind): Changed while() into for()
	(riscosify): Do the test on non-__RISCOSIFY_MASK bits only when
	configured for __UNIXLIB_PARANOID and use assert() for this.

	_dl_call_ctors() to call all shared library _init functions.

Tue Oct 16 01:55:08 CET 2007  John Tytgat  <John.Tytgat@aaug.net>

	* module/sul.s(sul_exec): finetune previous change by canonicalising
	given exec parameter using Run$Path and verifying if result is an
	existing file.  If not, fall back on original given parameter.

Sat Oct  6 22:24:36 CET 2007  John Tytgat  <John.Tytgat@aaug.net>

	Due to the large number of files where following changes were made, we

	(sul_fork): FP register f4-f7 were not restored.
	(sul_exec): canonicalise exec filename so that we can inherit process
	structures more reliably at swi_initialise; FP registers f4-f7 were

	* common/_taskhandle.s(__get_task_handle): used to request taskhandle
	from OS and result is stored as __ul_global.taskhandle.
	* sys/_syslib.s:
	Removed X bit from SWI calls made before setting up our UnixLib OS

	(__unixlib_get_fpstatus): prefix with function name.
	(__unixlib_set_fpstatus): likewise.

	* gcccompat/galloca.c: Likewise.
	(__gcc_alloca_return_address): strip off the PC flags of return value

	* gcccompat/_b_frame.s: Likewise.

Thu Aug 30 01:36:41 CET 2007  John Tytgat  <John.Tytgat@aaug.net>

	* gen-auto.pl(sul): Reverted previous (unwanted and undocumented)
	change as it required libscl to be present; use STRIP iso OBJCOPY
	to extract binary blob out of ELF file which has the advantage that
	this is already defined in GCC build system.

Fri Aug 24 01:38:30 CET 2007  John Tytgat  <John.Tytgat@aaug.net>

	* stdlib/system.c(system): whitespace changes; use EXIT_FAILURE for

	Likewise.
	* unix/getenv.c(__getenv_from_os): Updated comment on its API.
	* scl/_kcurskch.s(_kernel_current_stack_chunk): _kernel_chunk_stack
	was wrongly located and always returned NULL.
	* test/scl/test-kernel_current_stack_chunk.c: Added.

	build (or out-of-tree) of UnixLib works.

Wed Aug 8 19:03:03 2007  Lee Noar  <leenoar@sky.com>

	* common/symlinks.c: Don't use C based file access functions,
	because we may be called from one. Instead use low level OS
	functions.

Sat Aug 4 18:53:54 2007  Lee Noar  <leenoar@sky.com>

	* unix/dev.c: Add support for symlink files.
	* include/unixlib/buildoptions.h: Likewise.
	* include/unixlib/unix.h: Likewise.
	* common/objattr.c: Likewise.
	* common/exist.c: Likewise.
	* common/symlinks.c: New file. Implement symlink file processing.
	Primarily for use by GCC so that, eg, -lstdc++ will find symlink
	libstdc++.so which in turn points to libstdc++.6.0.8.so.

Sat Aug 4 17:39:01 2007  Lee Noar  <leenoar@sky.com>

	* vscript: Remove __pthread_cleanup_pop & __pthread_cleanup_push to
	make them visible from outside the DSO, as they could be called from
	a user program.

Sat Aug 4 14:40:20 2007  Lee Noar  <leenoar@sky.com>

	* vscript: Remove __pthread_start_ticker & __pthread_stop_ticker to
	make them visible from outside the DSO. Add __gcc_alloca_free_1 as
	it's only called by __gcc_alloca_free. Hiding it means a direct call
	instead of via the PLT and __gcc_alloca_free doesn't need to load
	the PIC register.

Tue Jul 10 00:53:25 CET 2007  John Tytgat  <John.Tytgat@aaug.net>

	* include/sys/cdefs.h(__REDIRECT, __REDIRECT_NTH): Define.

	already existing struct stat64 and avoid the #define stat stat64 hack.
	Update function declaration of fstat64 and lstat64.
	* unix/lstat.c(lstat64): Use struct stat64 iso struct stat.
	* unix/fstat.c(fstat64): Likewise.
	* unix/stat.c(stat64): Likewise.
	* common/riscosify.c(translate_or_null): Avoid cast.

Fri Jul 6 14:16:12 2007  Lee Noar  <leenoar@sky.com>

	* pthread/_context.s: Change PIC code to load PIC register from
	16 byte array instead of 4 byte array.
	* pthread/_yield.s: Likewise.
	* pthread/_ints.s: Likewise.
	* signal/_demangle.s: Likewise.
	* signal/_signal.s: Likewise.
	* common/_exist.s: Likewise.
	* common/_riscosify.s: Likewise.
	* gcccompat/_b_return.s: Likewise.
	* sys/_jmp.s: Likewise.
	* sys/_vfork.s: Likewise.
	* sys/_syslib.s: Likewise.

Sat Jun 30 11:55:12 2007  Lee Noar  <leenoar@sky.com>

	* sys/_syslib.s(__main): Using registers to receive data from
	crt1-riscos is not very elegant and we can't use the stack as it
	may not exist, so use a block of memory defined in crt1-riscos
	instead.

Tue Jun 19 20:00:43 2007  Lee Noar  <leenoar@sky.com>

	* sys/_syslib.s(__main): Change below (r2667) did not solve
	anything as it still uses the stack. Abandon using the stack
	altogether and use only registers to receive data from crt1-riscos.

Tue Jun 19 19:18:29 2007  Lee Noar  <leenoar@sky.com>

	* sys/_syslib.s(__main): Receive the _init/_fini function ptrs
	via registers as statically linked binaries may not have a
	valid stack pointer.

Sun Jun 17 16:23:01 2007  Lee Noar  <leenoar@sky.com>

	* include/unixlib/asm_dec.s: Remove XSOM_GOTFromAddr from the
	list of SWIs. The new PIC scheme makes it redundant.
	* include/swis.h: Change SWI number for SOM_DeregisterClient
	to account for the removal of SOM_Prologue and SOM_Resolver.

Sun Jun 17 14:30:21 2007  Lee Noar  <leenoar@sky.com>

	* gen-auto.pl: Remove -lpic from linker flags as it is no
	longer required.

Fri Jun 15 17:41:54 2007  Lee Noar  <leenoar@sky.com>

	* pthread/_context.s: Use new PIC register loading scheme.
	* pthread/_yields.s: Likewise.
	* pthread/_ints.s: Likewise.
	* common/_exist.s: Likewise.
	* common/_riscosify.s: Likewise.
	* gcccompat/_b_return.s: Likewise.
	* sys/_jmp.s: Likewise.
	* sys/_vfork.s: Likewise.
	* signal/_demangle.s: Likewise.
	* signal/_signal.s: Use new PIC register loading scheme.
	(__h_cback_common): Fix bug in DSO; when copying registers, start
	from the correct position in __cbreg.
	* sys/_syslib.s: Use new PIC register loading scheme.
	(__main): Retrieve values passed by crt1-riscos.o from the stack
	rather than from registers and store them as required. Register
	the program's _fini function with atexit() and call its _init
	function after library initialisation, but before main() is
	called. This replaces the call to __gccmain(). This is necessary
	as eventually, we'll also want to call the _init functions of all
	the shared libraries here too. Where the PIC register (v4) is used
	for non-PIC code, replace with v6.

Wed May 16 21:34:47 2007  Lee Noar  <leenoar@sky.com>

	* signal/_signal.s(__h_sigint): Fixed bug in DSO where r12 was assumed
	to be GOT pointer, but was actually reused for something else.

Wed Apr 11 03:21:40 CET 2007  John Tytgat  <John.Tytgat@aaug.net>

	* string/{_ffs.s,_ffsll.s}: the armv5 implemenation didn't work at
	all; replaced the non-armv5 implementation by a faster algorithm from
	David Seal.
	* pthread/_ints.s: DCB -> .asciz
	* gen-auto: moved from GCCSDK recipe/files/scripts/reconf-libunixlib-01
	to here; updated it so that the configure.ac is generated from
	configure.template filling in the AC_OUTPUT parameters; updated it
	to create TESTS for each test subdirectories.
	* test: reorganised the test files.
	* gcccompat/galloca.c: fixed wrong test on __UNIXLIB_PARANOID to
	determine if asserts need to be enabled or not.

Tue Apr 10 19:10:01 2007  Lee Noar  <leenoar@ntlworld.com>

	* libtool.m4: Remove occurrences of -fcall-used-v5 as it's now implied
	by -fPIC.

Mon Apr  9 21:16:29 CET 2007  John Tytgat  <John.Tytgat@aaug.net>

	Removed the last pre-UnixLib 5 only alloca implementation remains:
	* include/pthread.h(struct __pthread_thread): reduced alloca entry
	array of 3 pointers to just one pointer. The other array entries
	were not used.
	* pthread/newnode.c: following above change in struct
	__pthread_thread.
	* include/unixlib/asm_dec.s: likewise.
	* gcccompat/galloca.c: likewise.
	Enabled asserts for __UNIXLIB_PARANOID enabled builds.  Listen to
	__UNIXLIB_ALLOCA_FATAL to determine what to do if alloca() fails due
	to memory failure.
	(__gcc_alloca_longjmp_free): added, restores the alloca chunk list
	at longjmp() time.
	* sys/_jmp.s(setjmp,longjmp): alloca_list no longer exists so no
	longer (re)storing this weak value. longjmp() calls
	__gcc_alloca_longjmp_free() when the alloca chunk list is different
	than that setjmp() time. Soft-float builds are no longer storing
	the floating point registers.
	* include/setjmp.h(jmp_buf): following above change in struct
	jmp_buf.
	* gcccompat/_b_frame.s: fixed comments which got incorrectly changed
	by the aof2elf assembler conversion.
	* pthread/_ints.s(__pthread_protect_unsafe): don't resore pc flags in
	__pthread_unprotect_unsafe value when running on 26 bit systems (not
	needed for APCS-32).
	* sys/_syslib.s(use_existing_chunk): don't restore pc flags in
	__free_stack_chunk value when running on 26 bit systems (not needed
	for APCS-32).

Mon Apr  9 01:57:11 CET 2007  John Tytgat  <John.Tytgat@aaug.net>

	* signal/_signal.s(unrecoverable_error): don't test for FPU exception
	in soft-float build.
	* module/sul.s: explicit fpu specification as "fpa" as we're using
	FP instructions even in a soft-float build.
	* string/_memcpy.s: explicit arch specification as "armv6" to allow
	PLD instructions even if we're building with another -march compiler
	option.
	* README(<program name>$HeapMax): clarified it a little bit more.

Sat Apr  7 16:06:43 CET 2007  John Tytgat  <John.Tytgat@aaug.net>

	* stdlib/alloc.c(calloc): Detect size_t overflow for total size
	calculation as this might result in a non-NULL return value letting
	the caller believe it has a memory block that big.

Fri Apr  6 18:37:14 CET 2007  John Tytgat  <John.Tytgat@aaug.net>

	* include/stdio.h(__STDIOLIB__): Removed static __stdiolib function
	pointer to __stdioinit (). It wasn't needed anymore for quite some
	time.
	* stdio/{freopen.c,fputs.c,fgets.c,perror.c,putc.c,flsbuf.c,getc.c
	stdio.c,ungetc.c,setbuf.c,puts.c,putw.c,fwrite.c,tmpfile.c,gets.c
	getw.c,filbuf.c,fopen.c,fpos.c,fclose.c,popen.c,fread.c,fflush.c}:
	Removed __STDIOLIB__.

Fri Mar 30 19:16:19 2007  Lee Noar  <leenoar@ntlworld.com>

	* vscript: New file. A linker file containing a list of symbols that
	are global within the DSO, but should not be visible outside the library
	as they are not part of its API. This has the same effect as declaring
	each symbol as hidden. The file is actually a version script, hence the
	name, but version information is not used in this case.

	There are a number of advantages to hiding such symbols:
	a) The API/public interface of the library is cleaner and hides the
	   internal workings.
	b) Library initialisation is quicker as there are fewer relocations at
	   runtime (the static linker is able to resolve more symbols at build
	   time).
	c) Functions that are only ever called from within the library and are
	   hidden are called directly and not via the PLT making the library
	   more efficient.

	More symbols may be added to the list in the future as it becomes clearer
	which qualify for inclusion.

Tue Mar 27 02:11:36 CET 2007  John Tytgat  <John.Tytgat@aaug.net>

	* include/unixlib/asm_dec.s: include internal/defines.h; removed define
	TRUE/FALSE as it was not used.
	* include/unixlib/buildoptions.h(__UNIXLIB_CLZ_SUPPORTED): Removed,
	using __ARM_ARCH__ #define value instead.
	* string/_ffsll.s: Likewise.
	* string/_ffs.s: Likewise.
	* incl-local/internal/defines.h(__ARM_ARCH__,__ARM_ARCH_STR__): New
	file.
	* sys/_syslib.s: Reenabled runtime minimal ARM architecture check, was
	previously on XSCALE only, now based on __ARM_ARCH__ build and
	__get_cpu_arch runtime result.
	* README: updated with GCCSDK 4 build info.

Sat Mar 24 16:51:41 CET 2007  John Tytgat  <John.Tytgat@aaug.net>

	* incl-local/internal/elf-macros.s (NetSWI0): Fixed odd typo.

Tue Mar 20 20:03:46 2007  Lee Noar  <leenoar@ntlworld.com>

	* sys/_syslib.s: Change visibility of main function pointer to hidden.
	This prevents the dynamic linker from linking against main() in the
	executable.

Sun Mar 11 18:34:50 CET 2007  John Tytgat  <John.Tytgat@aaug.net>

	* incl-local/internal/elf-macros.s(UL_MEMORY_LAYOUT): Moving back to...
	* sys/_syslib.s: ...here.  Restored our stack ASCII art.
	* include/unixlib/asm_dec.s: Updated comments.

	* incl-local/internal/aof-macros.s: Removed, no longer used.
	* incl-local/internal/elf-macros.s(__UNIXLIB_ERRNO_THREADED): changed
	from assembler test to preprocessor test; (__SOFTFP__) no longer
	defined as 0 when it is not defined.
	* include/unixlib/buildoptions.h(__UNIXLIB_ELF): Removed, no longer
	used.
	* unix/features.c : Removed tests on __ELF__, this is always 'true'
	from now on.
	* unix/unix.c: Likewise.
	* pthread/_exit.s: Likewise.
	* signal/_signal.s: Likewise.
	* include/features.h: Likewise.
	* include/unixlib/unix.h: Likewise.
	* include/sys/cdefs.h: Likewise.

	* sys/_syslib.s: Likewise.
	* sys/mman.c: Likewise.
	* include: Removed svn:ignore property.  No longer relevant.
	* include/unixlib: Updated svn:ignore property, buildoptions.s is no
	longer used nor exists.
	* include/endian.h: Typo fix.
	* pthread/_context.s (__SOFTFP__): Test on existance and not on its
	value.
	* sys/_jmp.s: Likewise.
	* sys/_syslib.s: Likewise.
	* README: Documented __program_name.
	* sys/_alloca.s: Removed, no longer needed.

Sat Mar 10 21:21:23 CET 2007  John Tytgat  <John.Tytgat@aaug.net>

	* Used convert-unixlib.pl for the last time and stored its ELF
	result in SVN as trunk/gcc4/recipe/files/libunixlib.

Tue Mar 06 21:03:02 2007  Lee Noar  <leenoar@ntlworld.com>

	* source/clib/unixlib/unix.h: When not compiling for the
	shared library, use padding in place of the main function
	pointer to maintain structure offsets.
	* source/sys/_syslib.s: Always define the word that stores
	the main function pointer to maintain structure offsets,
	but only name it in the shared library.

Sun Mar 04 14:55:23 2007  Lee Noar  <leenoar@ntlworld.com>

	* source/unix/unix.c: Remove the dependency on the main symbol
	from the shared library by declaring and accessing it as a
	function pointer.
	* source/clib/unixlib/unix.h: Add main function pointer to
	__ul_global structure (shared library only).
	* source/clib/unixlib/asm_dec.s: Add main function pointer to
	GBL_* structure (shared library only).
	* source/sys/_syslib.s: In the shared library, initialise the
	main function pointer from the arguments passed to it in
	crti-riscos.asm and add main function pointer to the
	__ul_global structure.

Sun Jan 21 15:21:56 2007  Alex Waugh  <alex@alexwaugh.com>

	* source/clib/features.h, source/common/_exist.s: Change default
	value of __feature_imagefs_is_file to 1.

Fri Jan 19 15:56:39 2007  Lee Noar  <leenoar@ntlworld.com>

	* source/sys/_syslib.s: Undo changes made Thu Jan 18.
	* source/unix/unix.c: Change comment about _main.

Thu Jan 18 19:39:06 2007  Lee Noar  <leenoar@ntlworld.com>

	* source/sys/_syslib.s: For the ELF build, convert __main into
	an initialisation function called __unixlib_main that returns
	to its caller. This allows the call to _main (and ultimately
	main()) to be moved to the executable.
	* source/unix/unix.c: Don't compile _main() for the ELF build.
	It is moved to crti-riscos.asm so that it can call main() in the
	executable.

Sat Jan 13 19:06:23 2007  Lee Noar  <leenoar@ntlworld.com>

	* elf/libtool.m4: Change names of shared library and symlinks to
	something that is recognised by GCC (effects libunixlib and libm
	only). In the dlopen test, look for riscos at the end of the
	string rather than the beginning.

Fri Jan 12 21:29:54 2007  Lee Noar  <leenoar@ntlworld.com>

	* elf/convert-unixlib.pl: Link libunixlib.so with shared libgcc.

Sat Jan 06 01:25:35 2007  John-Mark Bell  <jmb@netsurf-browser.org>

	* source/pthread/_exit.s: Use v1 for function table pointer;
	a2 need not be preserved by callees under APCS

Fri Jan 05 17:13:54 2007  Lee Noar  <leenoar@ntlworld.com>

	* source/sys/_syslib.s (__main):
	Use correct PIC register which is v6 in this case, not v4.
	Make sure v6 (PIC register) is not used for anything else so that
	it is valid throughout the routine (anticipating future changes).

Thu Jan 04 18:17:23 2007  Lee Noar  <leenoar@ntlworld.com>

	* source/string/rawmemchr.c: Declare rawmemchr as alias for __rawmemchr
	otherwise rawmemchr is undefined.

Wed Dec 27 12:22:23 2006  Lee Noar  <leenoar@ntlworld.com>

	* source/clib/sys/elf.h: Correct spelling of R_ARM_JUMP_SLOT.

Wed Dec 27 03:08:02 CET 2006  John Tytgat  <John.Tytgat@aaug.net>

	* source/clib/{stdarg.h,stddef.h,varargs.h}: Restored as clean build
	of GCC 3.4.6 did not work anymore (got obfuscated by a copy in
	$GCCSDK_INSTALL_ENV/include/unixlib).
	* source/gcccompat/_b_frame.s: Previous change broke the ELF shared
	build.

Tue Dec 26 21:12:06 CET 2006  John Tytgat  <John.Tytgat@aaug.net>

	* source/gcccompat/{_b_return.s,_b_frame.s,_galloca.s,galloca.c}:
	finished and reworked the alloca, __builtin_return_address and
	__builtin_frame_address implementations for GCC 4
	This improves the gcc/g++ testsuite results.

Tue Dec 26 16:26:23 2006  Lee Noar  <leenoar@ntlworld.com>

	* source/pthread/_exit.s: Fix FIXMEs, ie, don't use
	__alloca_thread_free_all or ___arm_alloca_thread_free_all in
	ELF build.

Tue Dec 26 14:59:48 2006  Lee Noar  <leenoar@ntlworld.com>

	* source/sys/_syslib.s: Move DECLARE_FUNCTION of __trim_stack to the
	end of __free_stack_chain as technically they are part of the same
	function and also there's a possibility that the compiler may
	separate them in the resulting object file.

Mon Dec 25 17:03:19 2006  Lee Noar  <leenoar@ntlworld.com>

	* elf/convert-unixlib.pl: Link libpic.a into libunixlib.so and add
	version info to libunixlib.so and libm.so.

Wed Dec 20 20:47:17 CET 2006  John Tytgat  <John.Tytgat@aaug.net>

	* source/unix/unix.c: Uppercase start char of __unixlib_fatal() calls.
	* source/pthread/_exit.s(___arm_alloca_thread_free_all,
	__alloca_thread_free_all): disabled for ELF builds.  These should go
	for good when UnixLib build is ELF only.
	* source/signal/post.c: No longer make use of __backtrace_getfp() by
	using inline assembler.
	* source/clib/unixlib/sigstate.h(__backtrace_getfp): Removed
	declaration.
	* source/signal/_coredump.s(__backtrace_getfp()): Removed file.

	* source/scl/_kfpavailable.s(_kernel_fpavailable): Code moved from
	_syslib.s.
	* source/gcccompat/{_moddi3.s,_divdi3.s,_umoddi3.s,_udivdi3.s}
	(__moddi3.s,__divdi3.s,__umoddi3.s,__udivdi3.s): Removed (we've enabled
	those routines in gcc/libgcc/Makefile).
	* source/sys/_alloca.s(alloca,__alloca,__alloca_thread_free_all):
	Disabled code for ELF builds as it is not used.  This file should go
	for good when UnixLib build is ELF only.
	* source/sys/_syslib.s: Moved CHUNK_ definitions to asm_dec.s; Don't
	check for FPEmulator in soft-float builds; Don't export
	__stackchunk_magic_number; Changed termination CR/NL + NUL to NUL for
	fatal error messages; Renamed free_stack_chunk to __free_stack_chunk
	and exported it; Moved __builtin_return_address implementation to
	gcccompat/_b_return.s.; Moved _kernel_fpavailable implementation to
	scl/_kfpavailable.s.; Added important FIXME for __trim_stack; Added
	suggestion for __unixlib_fatal_got_msg improvement.
	* source/gcccompat/_b_return.s(__builtin_return_address): Code moved
	from _syslib.s and added some comments on necessary improvements.
	* source/gcccompat/_galloca.s: Added a couple of FIXMEs.
	* source/gcccompat/galloca.c: Removed __backtrace_getfp() call; Added
	FIXMEs and a couple of small changes (like do not access data from a
	free'd memory block).

Mon Dec 18 03:28:56 CET 2006  John Tytgat  <John.Tytgat@aaug.net>

	* source/stdlib/alloc(malloc,free,realloc,memalign,valloc,pvalloc,
	calloc,cfree,malloc_trim): prefixed routine names with '__' and made
	weak aliases for the original routine names to those implementations.
	* source/clib/limits.h(SHRT_MIN,INT_MIN,LONG_MIN,LONG_LONG_MIN): don't
	use C casting as these values should be evaluatable by the preprocessor
	too.
	This improves the g++ testsuite results.

Sun Dec 17 15:31:56 CET 2006  John Tytgat  <John.Tytgat@aaug.net>

	* source/{libm-dbl64/s_finite.c,libm-flt32/s_finitef.c}: enable
	call to (currently empty) hidden_def(). This will be needed when we're
	going to hide symbols from shared UnixLib version.
	* source/clib/{complex.h,math.h}: don't declare 'long double' math
	variants here when building UnixLib as they are	declared in the source
	code as aliases to the 'double' variants.
	* source/clib/mathdef.h(__NO_LONG_DOUBLE_MATH): no longer define it so
	this means we're supporting 'long double' math calls but they are in
	reality the same as 'double' ones.
	* source/clib/varargs.h: Removed (falling back on the gcc version).
	* source/clib/bits/mathcalls.h: Using an up-to-date version.
	* source/libm-complex/{creall.c,conjl.c,cabsl.c,cargl.c,cimagl.c}:
	Removed as they are elsewhere declared as aliases to their 'double'
	equivalents.
	* elf/convert-unixlib.pl(NO_LONG_DOUBLE): Defined, meaning we're going
	to alias the 'long double' math routines to the 'double' versions.
	This improves the gcc testsuite results.

Sat Dec 16 14:41:51 CET 2006  John Tytgat  <John.Tytgat@aaug.net>

	* source/clib/stddef.h: Removed (falling back on the gcc version).
	* source/clib/bits/mathdef.h(INFINITY): Removed duplicate definition,
	was also defined in source/clib/bits/inf.h.
	This improves the gcc/g++ testsuite results.

Sun Dec 10 21:03:51 CET 2006  John Tytgat  <John.Tytgat@aaug.net>

	* source/clib/stdarg.h: Removed (falling back on the gcc version).
	* source/string/_memcpy.s: Previous change got a build breaking typo.
	* source/string/_memset.s(memset,bzero): Made exported routines
	weakly defined.
	This improves the gcc/g++ testsuite results.

Sun Dec 10 15:29:31 CET 2006  John Tytgat  <John.Tytgat@aaug.net>

	* source/stdio/_printf.s(_printf,_fprintf,_sprintf,_vfprintf,_vprintf,
	_snprintf,_vsprintf,_vsnprintf): Removed.
	* source/stdio/printf.c(vsnprintf,vsprintf,snprintf,sprintf,vprintf,
	fprintf,printf): Prefixed the exported routines with '__' and created
	weak symbols to those routines.
	* source/stdio/vasprintf.c(vasprintf): Likewise.
	* source/stdio/asprintf.c(asprintf): Likewise.
	* source/crypt/crypt_util.c(encrypt_r,setkey_r): Likewise.
	* source/crypt/crypt-entry.c(crypt_r,fcrypt): Likewise.
	* source/string/strndup.c(strndup): Cleanup, weak_alias is always
	defined (even for AOF case).
	* source/string/strnlen.c(strnlen): Likewise.
	* source/resolv/inet_addr.c(inet_aton): Likewise.
	* source/string/_memcpy.s(memcpy,memmove,bcopy): Made exported routines

	* source/sys/_alloca.s: Likewise.
	* source/sys/_vfork.s: Add PIC instructions and declare functions
	and objects for ELF DSO.

	handlers where possible.

Thur Dec 07 19:42:15 2006  Lee Noar  <leenoar@ntlworld.com>

	* source/clib/errno.h: Ensure C linkage when used with C++
	compiler, otherwise there's a linkage disagreement with
	sys_errlist and sys_nerr in stdio.h.

	* source/incl-local/internal/elf-macros.s: As above, also add PIC instructions
	to __set_errno and __get_errno macros for ELF DSO.

Sun Dec 03 16:36:08 2006  Lee Noar  <leenoar@ntlworld.com>

	* source/pthread/_context.s: Add PIC instructions and declare

	Acorn's TCPIPLibs headers).

Wed Nov 29 20:36:22 CET 2006  John Tytgat  <John.Tytgat@aaug.net>

	* Removed build support for Norcroft and LCC compilers (preprocessor
	tests on __UNIXLIB_NORCROFT_BUILD, __CC_NORCROFT,
	__CC_NORCROFT_VERSION, __LCC__).

Sun Nov 28 22:01:02 2004  John Tytgat  <John.Tytgat@aaug.net>

	* !Help: mention APCS-32 explicitly.
	* Docs/ReadMe: UnixLib$pcnt is another internally used environment
	  variable.
	* source/psignal.c (psignal): Get rid of 'register'.
	* source/clib/errno.h: Remove __set_errno multiple define protection
	  as this shouldn't be needed.
	* source/clib/stdio.h (getc): Always use the getc() function instead
	  of using the macro equivalent (bug 122).
	* source/clib/unixlib/asm_dec.s (NetSWI*): Let all the macros import
	  __net_error themselves; Updated their comments; Simplified the
	  NetSWIsimple(0) even further.
	* source/clib/unixlib/buildoptions.h (__UNIXLIB_SET_DDEPREFIX): Added.
	* source/clib/unixlib/sigstate.h: __write_unrecoverable, __backtrace,
	  __core: Removed as it was nowhere used; __backtrace_getfp,
	  __ul_callbackfp: Added.
	* source/clib/netlib/{_accept.s, _bind.s, _connect.s, _getpeers.s,
	  _getpeerna.s, _getsockna.s, _getsockop.s, _gettsize.s, _listen.s,

	  working at all.
	* source/signal/_signal.s: Removed needless IMPORT of
	  __write_unrecoverable; Updated a couple comments; Take a snapshot
	  of CPSR during each hardware exception handler; Renamed __ul_errfp
	  to __ul_callbackfp as this should only be the fp and valid during
	  CallBack handler code (shared by the hardware exception handlers too),
	  during error handler this is NULL; Instead of reseting the exception
	  FP flags, we temporary disable FP traps (cfr bug 119); Pull
	  __ul_callbackfp in C$$data area.
	* source/signal/post.c: Removed needless __write_unrecoverable; Updated
	  write_backtrace so it becomes more useful and foolproof.

	* source/sound/dsp.c (__dspopen): Use ModuleTooOld error number instead
	  of 0.
	* source/pthread/{_ints.s, _yield.s}: Talk about APCS-32 instead of
	  APCS.
	* source/signal/sigexec.s: Likewise.
	* source/sys/_syslib.s: Likewise.
	* source/signal/_signal.s: Likewise. Temporary workaround for

	  into 1.
	* source/sys/errlist.c: Removed register usage.
	* source/unix/fnmatch.c: Reverted back to 1.2 version because making
	  1.3 to work involves pulling in too many other GLIBC based code.

Sun Oct 17 18:19:00 2004  John Tytgat  <John.Tytgat@aaug.net>

	* Docs/ReadMe: Added 'Building' section.

	  Uses build option __UNIXLIB_NORCROFT_BUILD to determine which float
	  ABI is used (GCC vs Norcroft).
	* source/unix/fnmatch.c: Disabled calling versioned_symbol(),

	* source/crypt/crypt_util.c: No need to define __GNU_LIBRARY__
	  explicitly because this is now done in features.h.

	  features.h file path.
	* source/module/sul.s: Fix inadvertant change to SWI base.

Sun Oct 10 17:37:38 2004  Alex Waugh  <alex@alexwaugh.com>

	* source/unix/uname.c: Cope with OS_ReadSysInfo returning 0

Fri Oct  8 12:56:32 2004  Peter Naulls  <peter@chocky.org>

	* source/clib/signal.h, source/signal/signal.c: Stub siginterrupt
	* source/clib/time.h, source/time/mktime.c, source/time/dysize.c,
	  source/time/timegm.c: Add support for mktime, timelocal, dysize.
	* source/clib/features.h, source/clib/unixlib/features.h:
	  Move features.h to same location as glibc. Make unixlib/features.h
	  include former for time being.
	* source/clib/sys/mount.h, source/sys/mount.c: Stub mount.h
	  functionality.
	* source/common/riscosify.c: Modify to work with libscl too.
	* source/unix/fnmatch.c: Update functionality.
	* source/locale/iconv.c, source/clib/iconv.h: Work with Norcroft
	  properly.

Tue Oct  5 16:24:01 2004  Peter Naulls  <peter@chocky.org>

	* source/clib/swis.h, source/locale/iconv.c: Update to sync with
	  John-Mark Bell's changes.
	* source/clib/netdb.h: Further improve visibility of macros
	  for unsupported functions.
	* source/unix/unix.c: Improve comment.
	* Docs/ReadMe: Update iconv URL.

Fri Sep 24 00:09:00 2004  John Tytgat  <John.Tytgat@aaug.net>

	* objs/Makefile.in: Predefined _GNU_SOURCE as quick fix for Norcroft
	  users after the 12 Sept 2004 change in post.c.  Better fix would
	  probably be to make sure that UnixLib is compilable with and without
	  _GNU_SOURCE defined.
	* source/clib/sys/debug.h (__debug): Added comment what __debug is
	  doing.
	* source/clib/unixlib/sigstate.h (valid_address): constify its
	  parameters
	* source/signal/post.c (valid_address): Likewise.
	* source/clib/unixlib/unix.h: Minor comment updating.
	* source/scl/_koscli.s: Likewise.
	* source/pthread/_ints.s: Reverted the signed/unsigned compare change
	  from 7 Sep 2004 on request from Alex.
	* source/sound/dsp.c: Test result of first __os_cli("RMEnsure...
	  call too.
	* source/locale/iconv.c: Likewise; Added CVS/RCS keyword header.
	* source/signal/_signal.s (return_quickly/__h_cback_common): Removed
	  unnessary teq pc,pc test (partly revert from 7 Sep 2004 change).
	  Feedback from Alex.
	* source/sys/_longlong.s (_ll_ufrom_d, _ll_sfrom_d, _ll_ufrom_f,
	  _ll_sfrom_f): Added, based on a patch from Jeffrey Lee for
	  gccsdk/gcc/libgcc/lib1aof.s.
	* source/sys/debug.c (__debug): Avoid crash when __u is bogus; Print
	  the has_process value too.
	* source/sys/exec.c (execve): execve() after fork() still means that
	  there is a parent so has_parent may not be reset.  Also necessary
	  to correctly identify when dde_prefix needs to be set & used in
	  unix.c (__unixinit, _exit).
	* source/unix/unix.c (__unixinit, _exit): dde_prefix may only be updated
	  and used to reset process' CSD when the process isn't a child; Added
	  assert that has_parent is always set in a process struct found via
	  UnixLib$env; (_exit) Removed test based on has_parent/___vret because
	  we want both parent & child to exit via __exit() and not directly
	  via __vret (resumely legacy code).

Fri Sep 17 19:20:35 2004  Peter Naulls  <peter@chocky.org>

	* Docs/ReadMe: Updated documentation.
	* source/clib/fnmatch.h: Updated fmatch.h from glibc.  Needs matching
	  C support still.
	* source/clib/langinfo.h, source/clib/nl_types.h,
	  source/clib/bits/locale.h, source/clib/locale/nl_langinfo.c:
	  Very basic langinfo support.
	* source/clib/netdb.h: Hide getaddrinfo declaration.
	* source/clib/stat.h, source/unix/stat.c: Make stat/stat64
	  more like glibc to avoid problems with forward declarations.
	* source/signal/signal.c: Remove warning.  

Fri Sep 17 19:20:35 2004  John-Mark Bell  <jmb@netsurf-browser.org>

	* source/clib/semaphore.h, source/pthread/sem.c,
	  source/clib/pthread.h: Semaphore support.
	* source/clib/netdb.h, source/netlib/getnameinfo.c: getnameinfo
	  support.

	* source/signal/post.c: Remove warnings
	* source/sound/dsp.c: Be more careful about opening and closing
	  the DRender: filesystem.
	* source/clib/swis.h, source/clib/iconv.h, source/clib/iconv.c:
	  Interface to John-Mark Bell's iconv support module, instead
	  of requiring the large external iconv library.

	* source/termios/tcsetattr.c: Fix setting of VMIN/VTIME
	* source/unix/ioctl.c: NULL arguments to ioctl are ok.
	* source/unix/tty.c: Implement usage of VTIME, correct setting/usage
	  of VMIN. 

Wed Sep  8 18:04:02 2004  John Tytgat  <John.Tytgat@aaug.net>

	* objs/.cvsignore: Added sound directory.
	* source/sys/_mem.s: Go back to v1.4 (i.e. before the Sep 7 2004 changes)
	  as there were, yet unidentified, problems with it.
	* source/sound/dsp.c (__dspopen): Enforce DigitalRenderer version 0.51.
	* source/sys/vfork.c: Include sys/debug.h instead of stdio.h when DEBUG
	  is defined.

Wed Sep  8 10:13:16 2004  Peter Naulls  <peter@chocky.org>

	  source/clib/unixlib/dev.h, source/sound/dsp.h,
	  source/unix/dev.c: Experimental /dev/dsp support.

Tue Sep  7 16:03:14 2004  John Tytgat  <John.Tytgat@aaug.net>

	* source/sys/exec.c: Likewise.
	* source/clib/unistd.h: Added lseek64() prototype.
	* source/clib/sys/stat.h: Added lstat64(), fstat64() prototype.
	* source/clib/sys/un.h: Added RCS/CVS keywords.
	* source/clib/unixlib/asm_dec.s: Moved chunk and error definitions from
	  source/module/sul.s to here as SharedUnixLibrary_SWIChunk and
	  SharedUnixLibrary_ErrorChunk; Formally defined the
	  SharedUnixLib_Error_* errors; Incorrect SWI error exit code was
	  generated with objasm; TABified.
	* source/clib/unixlib/sigstate.h: Aesthetic change; declared
	  valid_address().
	* source/clib/unixlib/unix.h: Removed __env_read() declaration.
	  Adjusted comment on UnixEnv environment prefix.
	* source/common/unixify.c (__unixify): Suffix swapping could access

	* source/sys/_exec.s: Space injections.
	* source/sys/_syslib.s: Introduced startup errors instead of VDU
	  writing; Ensuring SUL v1.02 instead of v1.00; Rename __cli ->
	  __uixlib_cli, __himem -> __image_rw_himem; a1 (on entry) of OS_Exit
	  must point to a filled in RISC OS error block; Define stack_corrupt_msg
	  and stack_corrupt conditionally; Calling __unixlib_fatal a 2nd time
	  results in panic calling OS_Exit; (stack_overflow_common) executing
	  signalhandler stack check *before* validity stack check otherwise you
	  get the wrong fatal error message.
	* source/sys/_vfork.s: Added comments.
	* source/sys/mman.c (__munmap_all): Updated comments.
	* source/sys/vfork.c: Minor cleanup.
	* source/unix/unix.c: Removed __unixlib_cli declaration; Be more

	  definition.

Sun Aug  8 12:57:59 2004  Graham Shaw  <gdshaw@sagitta.demon.co.uk>

	* unix/getenv.c: Complete rewrite. Use __UNIX_ENV_PREFIX when
	environment names interact with global RISC OS environment. Support
	for new setenv, clearenv and unsetenv functions. Remove need for static
	__envcnt and __envsize variables. __intenv now only checks RISC OS
	environment. Allow for environ to have been allocated in parent process.

	* unix/pipe.c: Change call to __intenv and __permstr.

	* unix/putenv.c: Rewritten to not modify argument and allow NAME to be
	removed from the environment. Use setenv to add and unsetenv to remove.

	* unix/setenv.c: New file to provide setenv, unsetenv and clearenv.

	* unix/unix.c: Add default value for UnixFS$/pipe to use Wimp$ScrapDir,
	needed for cases when programs use pipes but do not set UnixFS$/pipe.
	Remove __permstr and use strdup instead. Make __decstrtoui external
	and check END argument before writing to it. Collect environment from
	parent process if we are a child. Use monotonic clock to generate
	process id (this will change).
