◆ areDefaultedSMFStillPOD()

bool TargetInfo::areDefaultedSMFStillPOD ( const LangOptions & LangOpts ) const

virtual

Controls whether explicitly defaulted (= default) special member functions disqualify something from being POD-for-the-purposes-of-layout.

Historically, Clang didn't consider these acceptable for POD, but GCC does. So in newer Clang ABIs they are acceptable for POD to be compatible with GCC/Itanium ABI, and remains disqualifying for targets that need Clang backwards compatibility rather than GCC/Itanium ABI compatibility.

Controls whether global operator delete is called by the deleting destructor or at the point where ::delete was called.

Historically Clang called global operator delete outside of the deleting destructor for both Microsoft and Itanium ABI. In Clang 21 support for ::delete was aligned with Microsoft ABI, so it will call global operator delete in the deleting destructor body.

◆ hasProtectedVisibility()

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

inlinevirtual

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.
