adjustment. If so, we merge the adjustment into the existing one.

a call. This fixes Prolangs-C++/deriv2, kimwitu++, and Misc-C++/bigfib on X86 with -enable-x86-fastcc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22023 91177308-0d34-0410-b5e6-96231b3b80d8
2005-05-14Pass i64 values correctly split in reg/mem to fastcc calls.Chris Lattner
This fixes fourinarow with -enable-x86-fastcc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22022 91177308-0d34-0410-b5e6-96231b3b80d8
2005-05-14Use target-specific nodes for calls. This allows the fastcc code to not haveChris Lattner
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
