Bug ID: 77379 Summary: incorrect mangling for non-virtual adjustor thunk (missing abi tag) Product: gcc Version: 6.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: richard-gccbugzilla at metafoo dot co.uk Target Milestone: --- GCC does not emit ABI tags from a function return type when mangling an adjustor thunk (see example in https://llvm.org/bugs/show_bug.cgi?id=28997). If this is intentional, and there's some good reason to omit the abi_tag mangling here, let us know and we'll suppress them from Clang too.
