PowerPC .gnu.attributes
This patch extends Tag_GNU_Power_ABI_FP to cover long double ABIs, makes the assembler warn about undefined tag values, and removes similar warnings from the linker. I think it is better to not warn in the linker about undefined tag values as future extensions to the tags then won't result in likely bogus warnings. This is consistent with the fact that an older linker won't warn on an entirely new tag. include/ * elf/ppc.h (Tag_GNU_Power_ABI_FP): Comment. bfd/ * elf-bfd.h (_bfd_elf_ppc_merge_fp_attributes): Declare. * elf32-ppc.c (_bfd_elf_ppc_merge_fp_attributes): New function.
