IntrusiveRefCntPtr vs std::shared_ptr
why llvm contains IntrusiveRefCntPtr instead of using only std::shared_ptr? IntrusiveRefCntPtr widely used in llvm and clang source code.
Due to better performance?
for example in main func of clang frontend:
int cc1_main(ArrayRef<const char *> Argv, const char *Argv0, void *MainAddr) {
ensureSufficientStack();
std::unique_ptr<CompilerInstance> Clang(new CompilerInstance());
IntrusiveRefCntPtr<DiagnosticIDs> DiagID(new DiagnosticIDs());
IntrusiveRefCntPtr<DiagnosticOptions> DiagOpts = new DiagnosticOptions();
