Since only the GNU_PROPERTY_X86_UINT32_VALID bit may be set in data-only relocatable objects which don't contain any instructions, linker shouldn't mask out the GNU_PROPERTY_X86_UINT32_VALID bit when merging GNU_PROPERTY_X86_XXX bits. Otherwise, linker output doesn't contain GNU_PROPERTY_X86_XXX property with any data-only relocatable inputs. This patch keeps the GNU_PROPERTY_X86_UINT32_VALID bit and updates readelf to print "<None>" if GNU_PROPERTY_X86_XXX property only has the GNU_PROPERTY_X86_UINT32_VALID bit. bfd/ * elfxx-x86.c (_bfd_x86_elf_parse_gnu_properties): Don't mask out the GNU_PROPERTY_X86_UINT32_VALID bit. binutils/ * readelf.c (decode_x86_isa): Print <None> if bitmask only contains the GNU_PROPERTY_X86_UINT32_VALID bit. (decode_x86_feature_1): Likewise. (decode_x86_feature_2): Likewise.
