to do ugly hackery to avoid emitting code like this: call foo mov vreg, EAX adjcallstackup ... If foo is a fastcc call and if vreg gets spilled, we might end up with this: call foo mov [ESP+offset], EAX ;; Offset doesn't consider the 12! sub ESP, 12 Which is bad. The previous hacky code to deal with this was A) gross B) not good enough. In particular, it could miss cases and emit the bad code above. Now we always emit this: call foo adjcallstackup ... mov vreg, EAX directly. This makes fastcc with callees poping the stack work much better. Next stop (finally!) really is tail calls. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22021 91177308-0d34-0410-b5e6-96231b3b80d8 |
