[PATCH] D157252: [clang][ExprConst] Handle 0 type size in builtin_memcpy etc.

[Shafik Yaghmour via Phabricator via cfe-commits]

shafik added inline comments.


================
Comment at: clang/lib/AST/ExprConstant.cpp:9512
     uint64_t TSize = Info.Ctx.getTypeSizeInChars(T).getQuantity();
+    if (TSize == 0)
+      return false;
----------------
I think we should issue a diagnostic, we don't have any indication that this is failing, let alone because the destination object size is zero.
