[PATCH] D136285: Bad optimization with alloca and intrinsic function stackrestore

[Jamie Schmeiser via Phabricator via llvm-commits]

I found the following in clang/lib/CodeGen/CGCall.cpp:

  // Insert a stack save if we're going to need any inalloca args.                                                                                                                                                                                            
  if (hasInAllocaArgs(CGM, ExplicitCC, ArgTypes)) {
    assert(getTarget().getTriple().getArch() == llvm::Triple::x86 &&
           "inalloca only supported on x86");
    Args.allocateArgumentMemory(*this);
  }

How universal is inalloca?  Or is this something different?
