New Revision: 46125
URL: http://llvm.org/viewvc/llvm-project?rev=46125&view=rev
Log:
* Introduce a new SelectionDAG::getIntPtrConstant method
and switch various codegen pieces and the X86 backend over
to using it.
* Add some comments to SelectionDAGNodes.h
* Introduce a second argument to FP_ROUND, which indicates
whether the FP_ROUND changes the value of its input. If
not it is safe to xform things like fp_extend(fp_round(x)) -> x.
