[llvm-commits] CVS: llvm/include/llvm/CodeGen/SelectionDAG.h

[Evan Cheng]

Changes in directory llvm/include/llvm/CodeGen:

SelectionDAG.h updated: 1.96 -> 1.97
---
Log message:

Added SelectionDAG::InsertISelMapEntry(). This is used to workaround the gcc
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).
