hans added a comment.
I don't really know about the functionality here, just adding a few comments on
the code itself.
================
Comment at: clang/lib/CodeGen/CGDebugInfo.cpp:1966
+ QualType PointeeTy = D.getTypePtr()->getPointeeType();
+ llvm::DIType *DI = getOrCreateType(PointeeTy, getOrCreateFile(Loc));
+ CI->setMetadata("heapallocsite", DI);
----------------
I don't really know this code, but does this also work for void pointers, i.e.
the if statement in the old code was unnecessary?
================
Comment at: clang/test/CodeGen/debug-info-codeview-heapallocsite.c:19
+// FIXME: Currently not testing that call_alloc_void has metadata because the
+// metadata is not set when the type is void.
+
----------------
Is it not set with your new code though?
================
Comment at: llvm/lib/CodeGen/AsmPrinter/CodeViewDebug.cpp:1078
+ MCSymbol *EndLabel = std::get<1>(HeapAllocSite);
+ DIType *DITy = cast<DIType>(std::get<2>(HeapAllocSite));
+
----------------
Is the cast necessary? Couldn't the tuple member be made a DIType* in the first
place?
================
Comment at: llvm/test/CodeGen/X86/label-heapallocsite.ll:1
+; RUN: llc -O0 < %s | FileCheck %s
+; FIXME: Add test for llc with optimizations once it is implemented.
----------------
Does llc have a "-fast-isel" flag or similar that could be used instead, to
make it more clear that it's fast-isel that's significant for the test?
================
Comment at: llvm/test/CodeGen/X86/label-heapallocsite.ll:16
+; ModuleID = 'heapallocsite.c'
+source_filename = "heapallocsite.c"
+target datalayout = "e-m:w-i64:64-f80:128-n8:16:32:64-S128"
----------------
I guess the ModuleID and source_filename are unnecessary, so I'd dro pthem.
================
Comment at: llvm/test/CodeGen/X86/label-heapallocsite.ll:51

"target-features"="+cx8,+mmx,+sse,+sse2,+x87" "unsafe-fp-math"="false"
"use-soft-float"="false" }
+
----------------
Both sets of attributes seem unnecessary so could probably be removed.
