c: support attribs starting with '_'
Commit Message
Support attributes starting with dash (like _noreturn, or __Noreturn).
Note the only consumer of lookup_attribute_by_prefix comes from IPA ICF.
Patch can bootstrap on x86_64-linux-gnu and survives regression tests.
Ready to be installed?
Thanks,
Martin
