PR ld/10956
* ld.h (struct args_type): Rename 'relax' field to 'disable_target_specific_optimizations' and turn it into a tri-state variable. (RELAXATION_DISABLED_BY_DEFAULT): New macro. (RELAXATION_DISABLED_BY_USER): New macro. (RELAXATION_ENABLED): New macro. (DISABLE_RELAXATION): New macro. (ENABLE_RELAXATION): New macro. * lexsup (enum option_values): Add OPTION_NO_RELAX. (struct ld_options): Add --no-relax. (parse_args): Handle OPTION_NO_RELAX. Use DISABLE_RELAXATION and ENABLE_RELAXATION macros. * ldlang.c (lang_relax_sections): Use RELAXATION_ENABLED macro. (lang_process): Likewise. * ldmain.c (main): Initialise disable_target_specific_optimizations field. (multiple_definition): Use RELAXATION_ENABLED macro. * ld.texinfo: Document new command line option. * emultempl/alphaelf.em: Remove --no-relax option. (before_allocation): Test RELAXATION_DISABLED_BY_USER macro. Use ENABLE_RELAXATION macro. * emultempl/avrelf.em: (after_allocation): Test RELAXATION_ENABLED macro. * emultempl/cr16elf.em: Remove --no-relax option. (before_allocation): Test RELAXATION_DISABLED_BY_USER macro. Use ENABLE_RELAXATION macro. * emultempl/crxelf.em: Remove --no-relax option. (before_allocation): Test RELAXATION_DISABLED_BY_USER macro. Use ENABLE_RELAXATION macro. * emultempl/mmix-elfnmmo.em: (before_allocation): Use ENABLE_RELAXATION macro. * emultempl/needrelax.em: (before_allocation): Use ENABLE_RELAXATION macro. * emultempl/ppc32elf.em: (before_allocation): Test RELAXATION_DISABLED_BY_DEFAULT macro. Use ENABLE_RELAXATION macro. * emultempl/sh64elf.em: (before_allocation): Test RELAXATION_ENABLED macro. Use DISABLE_RELAXATION macro. * emultempl/xtensaelf.em: Remove --no-relax option. (before_allocation): Test RELAXATION_ENABLED macro. Use ENABLE_RELAXATION macro.
