[PATCH] D117356: InstructionCombining: avoid eliding mismatched alloc/free pairs

[Dávid Bolvanský via Phabricator via llvm-commits]

xbolva00 added inline comments.


================
Comment at: llvm/lib/Analysis/MemoryBuiltins.cpp:116
 // know which functions are nounwind, noalias, nocapture parameters, etc.
 static const std::pair<LibFunc, AllocFnsTy> AllocationFnData[] = {
+    {LibFunc_malloc,                            {MallocLike,       1,  0, -1, -1, MallocFamily::Malloc}},
----------------
Anyway I still think Clang should add attributes and metadata as more general solution wrt this hardcoded list.
