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.

If no object files have .eh_frame, but some shared library does, then ld creates a .eh_frame_hdr section using the shared library bfd. This is silly since shared library .eh_frame sections don't contribute to the output .eh_frame and thus no .eh_frame_hdr is needed. Also, the bfd section list and count is cleared for shared libraries, and a zero section count used as a flag in lang_check to omit a call to bfd_merge_private_bfd_data for shared libraries. If we create a section on a shared lib bfd then ld will wrongly attempt to merge the shared library private bfd data. PR 17742 * ld/emultempl/elf32.em (gld${EMULATION_NAME}_after_open): Exclude shared libraries in loop looking for .eh_frame sections. Similarly for build-id loop. -

The AVR target has an elf header flag to indicate if an object was assembler ready for linker relaxation. If a partial link is performed then it is important that the link-relax flag in the output object is set correctly, otherwise, during the final link, we might try to perform linker relaxation on code that was not assembled suitably. As the link-relax elf header covers the entire object file we must be conservative when setting the flag in the output object, so, for a partial link, any input object that does not have the link-relax flag set will cause the output object to also not have the link-relax flag set. This conservative approach could be softened in future, we only need to disable the link relax flag if an input file is not marked link-relax ready, and the input file contains a relaxable section. However, I've left this optimisation for a later day. For the final link I've overloaded the use of the link-relax elf header flag, in a final executable, the flag now indicates if the executable was built with linker relaxation on or not. ld/ChangeLog: * emultempl/avrelf.em: Add include of elf/avr.h.

The AVR target uses a bit in the elf header flags to indicate if the object was assembled ready for linker relaxation. Previously this flag was always set, even when the object was not assembled ready for linker relaxation. This patch moves setting of the flag into the assembler, and sets it only when the assembler is preparing the file for linker relaxation. bfd/ChangeLog: * elf32-avr.c (bfd_elf_avr_final_write_processing): Don't set EF_AVR_LINKRELAX_PREPARED unconditionally. gas/ChangeLog: * config/tc-avr.c: Add include for elf/avr.h.

The old code missed testing bfd_link_hash_undefweak, and wrongly excluded bfd_link_hash_common symbols. It is also clearer to invert the set of enum bfd_link_hash_type values tested. bfd_link_hash_indirect and bfd_link_hash_warning will never appear here. * ldexp.c (update_definedness): Correct logic setting by_object.
