* Added SelectionDAG::InsertISelMapEntry(). This is used to workaround the gccEvan Cheng2006-02-091-2/+8
| | | | | | | | | problem where it inline the map insertion call too aggressively. Before this change it was producing a frame size of 24k for Select_store(), now it's down to 10k (by calling this method rather than calling the map insertion operator). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26094 91177308-0d34-0410-b5e6-96231b3b80d8
* More changes to reduce frame size.Evan Cheng2006-02-091-236/+72
| | | | | | | | | | Move all getTargetNode() out of SelectionDAG.h into SelectionDAG.cpp. This prevents them from being inlined. Change getTargetNode() so they return SDNode * instead of SDOperand to prevent copying. It should also help compilation speed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26083 91177308-0d34-0410-b5e6-96231b3b80d8
