[PATCH] D115440: [clang][auto-init] Provide __builtin_alloca_uninitialized

[Alexander Potapenko via Phabricator via cfe-commits]

glider added a comment.

I second this proposal.
https://reviews.llvm.org/D60548 suggests to handle this case using a pragma, 
but the required change seems to be more intrusive.



================
Comment at: clang/lib/CodeGen/CGBuiltin.cpp:3436
 
   case Builtin::BI__builtin_alloca_with_align: {
     Value *Size = EmitScalarExpr(E->getArg(0));
----------------
For the sake of completeness, shall we also implement an uninitialized version 
of __builtin_alloca_with_align()?
