Robert Scott 506ec38e7f cc-wrapper, clang: use new mechanism to selectively unsupport zerocallusedregs ... this allows a compiler derivation to provide a hardeningUnsupportedFlagsByTargetPlatform passthru attr that will be called with the targetPlatform to determine the unsupported hardening flags for that platform. we can do this because even though a clang compiler is multi-target by nature, cc-wrapper effectively fixes the target platform at wrapping time. otherwise we'd have to sniff the intended target at runtime, which wouldn't be fun at all. the advantage of using a new attribute instead of allowing hardeningUnsupportedFlags to optionally be a function is that hardeningUnsupportedFlags retains its simple overriding pattern for simple cases (i.e. `(prev.hardeningUnsupportedFlags or []) ++ [ "foo" ]` ) which will continue to work as long as the bottom-most function of hardeningUnsupportedFlagsByTargetPlatform falls back to hardeningUnsupportedFlags.		2024-01-21 11:16:07 +00:00
