Reid Kleckner	3cbfa1617f	Add an inalloca flag to allocas ... Summary: The only current use of this flag is to mark the alloca as dynamic, even if its in the entry block. The stack adjustment for the alloca can never be folded into the prologue because the call may clear it and it has to be allocated at the top of the stack.

Reid Kleckner	ad60d3c304	Change inalloca rules to make it only apply to the last parameter ... This makes things a lot easier, because we can now talk about the "argument allocation", which allocates all the memory for the call in one shot. The only functional change is to the verifier for a feature that hasn't shipped yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199434 91177308-0d34-0410-b5e6-96231b3b80d8	2014-01-16 22:59:24 +00:00
