AVR: Assembler now prepares for linker relaxation by default.
Have the assembler prepare for linker relaxation by default. This means that users will be able to make use of linker relaxation without having to adjust the assembler flags, this can make life easier when compiling libraries. Having this on by default in the assembler should make no difference to the assembler code produced, however, some of the debug information will be slightly less compressed. A few tests needed to be updated as a result of this change as they relied on linker relaxation support being off by default. I've tightened up the definition of which sections can be relaxed on AVR as part of this commit, the assembler used to think that all non-debugging sections could be relaxed, when in reality only code sections can be relaxed for AVR. The previous definition was not dangerous, just over cautious. The new tighter definition allows an extra test (gas/testsuite/gas/all/forward.d) to continue to pass. gas/ChangeLog: * config/tc-avr.c (struct avr_opt_s): Change link_relax to no_link_relax, extend comment. (enum options): Add new OPTION_NO_LINK_RELAX. (md_longopts): Add entry for -mno-link-relax. (md_parse_option): Handle OPTION_NO_LINK_RELAX, and update OPTION_LINK_RELAX. (md_begin): Initialise linkrelax from no_link_relax. (md_show_usage): Include -mno-link-relax option. (relaxable_section): Only allocatable code sections can be relaxed. * config/tc-avr.h (TC_LINKRELAX_FIXUP): Define. gas/testsuite/ChangeLog: * gas/all/gas.exp: Test will not pass on AVR due to linker relaxation support. * gas/avr/noreloc_withoutrelax.d: Add -mno-link-relax option. * gas/avr/link-relax-elf-flag-clear.d: Likewise. ld/testsuite/ChangeLog: * ld/testsuite/ld-avr/relax-elf-flags-02.d: Add -mno-link-relax option. * ld/testsuite/ld-avr/relax-elf-flags-03.d: Likewise. * ld/testsuite/ld-avr/relax-elf-flags-04.d: Likewise. * ld/testsuite/ld-avr/relax-elf-flags-05.d: Likewise. * ld/testsuite/ld-avr/relax-elf-flags-06.d: Likewise.
