[llvm-commits] Issue with Win64 local area stack offset

I might be wrong, but it doesn't seem so. Call lowering code only puts
the arguments assuming
that there is a shadow space already allocated, but nothing inside
prologue allocates it
(this was what "StackSize +=32" used for).

Please verify your observations on:
1. Function in case of eliminated FP
2. Function with just 2 arguments

Thanks!
