Subject: [PATCH] c: support attribs starting with '_'
Date: Wed, 5 Oct 2022 13:42:37 +0200 [thread overview]
Message-ID: <6876baac-15f9-0450-72ec-1f0b85348392@suse.cz> (raw)
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
