* Remove isImm(), isReg(), and friends, in favor of Dan Gohman2008-09-139-29/+30
| | | | | | | | | isImmediate(), isRegister(), and friends, to avoid confusion about having two different names with the same meaning. I'm not attached to the longer names, and would be ok with changing to the shorter names if others prefer it. llvm-svn: 56189
* Define CallSDNode, an SDNode subclass for use with ISD::CALL.Dan Gohman2008-09-135-59/+73
| | | | | | | | | | | | | Currently it just holds the calling convention and flags for isVarArgs and isTailCall. And it has several utility methods, which eliminate magic 5+2*i and similar index computations in several places. CallSDNodes are not CSE'd. Teach UpdateNodeOperands to handle nodes that are not CSE'd gracefully. llvm-svn: 56183
* On some targets, non-move instructions can become move instructions because ↵Evan Cheng2008-09-121-14/+28
| | | | | | | | | | | | of coalescing. e.g. vr2 = OR vr0, vr1 => vr2 = OR vr1, vr1 // after coalescing vr0 with vr1 Update the value# of the destination register with the copy instruction if that happens. llvm-svn: 56165
* Change ConstantSDNode and ConstantFPSDNode to use ConstantInt* andDan Gohman2008-09-125-14/+22
| | | | | | | | | | | | | | | | | | | | | | | | ConstantFP* instead of APInt and APFloat directly. This reduces the amount of time to create ConstantSDNode and ConstantFPSDNode nodes when ConstantInt* and ConstantFP* respectively are already available, as is the case in SelectionDAGBuild.cpp. Also, it reduces the amount of time to legalize constants into constant pools, and the amount of time to add ConstantFP operands to MachineInstrs, due to eliminating ConstantInt::get and ConstantFP::get calls. It increases the amount of work needed to create new constants in cases where the client doesn't already have a ConstantInt* or ConstantFP*, such as legalize expanding 64-bit integer constants to 32-bit constants. And it adds a layer of indirection for the accessor methods. But these appear to be outweight by the benefits in most cases. It will also make it easier to make ConstantSDNode and ConstantFPNode more consistent with ConstantInt and ConstantFP. llvm-svn: 56162

* Rename ConstantSDNode::getValue to getZExtValue, for consistencyDan Gohman2008-09-1211-128/+143
| | | | | | | with ConstantInt. This led to fixing a bug in TargetLowering.cpp using getValue instead of getAPIntValue. llvm-svn: 56159

* Fix PR2748. Avoid coalescing physical register with virtual register which ↵Evan Cheng2008-09-112-0/+70
| | | | | | | | | | | would create illegal extract_subreg. e.g. vr1024 = extract_subreg vr1025, 1 ... vr1024 = mov8rr AH If vr1024 is coalesced with AH, the extract_subreg is now illegal since AH does not have a super-reg whose sub-register 1 is AH. llvm-svn: 56118
