◆ addHeapAllocSiteMetadata()

void CGDebugInfo::addHeapAllocSiteMetadata	(	llvm::CallBase *	CallSite,
		QualType	AllocatedTy,
		SourceLocation	Loc
	)

Add heapallocsite metadata for MSAllocator calls.

◆ AddStringLiteralDebugInfo()

void CGDebugInfo::AddStringLiteralDebugInfo	(	llvm::GlobalVariable *	GV,

DebugInfo isn't attached to string literals by default.

While certain aspects of debuginfo aren't useful for string literals (like a name), it's nice to be able to symbolize the line and column information. This is especially useful for sanitizers, as it allows symbolization of heap-buffer-overflows on constant strings.
