##### 9.42.5.7 absolute-literals

The `absolute-literals` and `no-absolute-literals` directives control the absolute vs. PC-relative mode for `L32R` instructions. These are relevant only for Xtensa configurations that include the absolute addressing option for `L32R` instructions.

             .begin [no-]absolute-literals
             .end [no-]absolute-literals

These directives do not change the `L32R` mode—they only cause the assembler to emit the appropriate kind of relocation for `L32R` instructions and to place the literal values in the appropriate section. To change the `L32R` mode, the program must write the `LITBASE` special register. It is the programmer's responsibility to keep track of the mode and indicate to the assembler which mode is used in each region of code.

If the Xtensa configuration includes the absolute `L32R` addressing option, the default is to assume absolute `L32R` addressing unless the ‘`--no-absolute-literals`’ command-line option is specified. Otherwise, the default is to assume PC-relative `L32R` addressing. The `absolute-literals` directive can then be used to override the default determined by the command-line options.
