Reid Kleckner 39ee70ca76 [WinEH] Make llvm.x86.seh.restoreframe work for stack realignment prologues ... The incoming EBP value points to the end of a local stack allocation, so we can use that to restore ESI, the base pointer. Once we do that, we can use local stack allocations. If we know we need stack realignment, spill the original frame pointer in the prologue and reload it after restoring ESI. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@241648 91177308-0d34-0410-b5e6-96231b3b80d8		2015-07-07 23:45:58 +00:00
