--- Comment #7 from Christophe Lyon <clyon at gcc dot gnu.org> ---
The first time using_thumb_only is called (bfd/elf32-arm.c in binutils
sources), globals->obfd points to a bfd whose filename is:
"pr118715.exe.lto-pr118715.o (symbol from plugin)"
(with "(symbol from plugin)" part of the filename)
and it sees its Tag_CPU_arch_profile as 0.
However, when using readelf to look at the attributes section in
pr118715.exe.lto-pr118715.o, it does have
Tag_CPU_arch_profile: Microcontroller
So why does bfd_elf_get_obj_attr_int return 0?
I'm not sure how the lto-plugin really works? I've noticed that
pr118715.exe.lto.ltrans0.o does not have an attributes section, but when/how is
it used? I don't see it on linker command line
