The list is guaranteed to have at most one entry per feature.

Returns
False on error.

Determine whether the _BitInt type is supported on this target.

This limitation is put into place for ABI reasons.

◆ hasProtectedVisibility()

virtual bool clang::TargetInfo::hasProtectedVisibility ( ) const

Does this target support "protected" visibility?

Any target which dynamic libraries will naturally support something like "default" (meaning that the symbol is visible outside this shared object) and "hidden" (meaning that it isn't) visibilities, but "protected" is really an ELF-specific concept with weird semantics designed around the convenience of dynamic linker implementations. Which is not to suggest that there's consistent target-independent semantics for "default" visibility either; the entire thing is pretty badly mangled.
