* Remove getAllocatedRegNum(). Use getReg() instead.Alkis Evlogimenos2004-02-131-1/+1

* Change MachineBasicBlock's vector of MachineInstr pointers into anAlkis Evlogimenos2004-02-121-16/+19
| | | | | | | | | ilist of MachineInstr objects. This allows constant time removal and insertion of MachineInstr instances from anywhere in each MachineBasicBlock. It also allows for constant time splicing of MachineInstrs into or out of MachineBasicBlocks. llvm-svn: 11340
* Do not use MachineOperand::isVirtualRegister either!Chris Lattner2004-02-101-3/+3

* Change interface of MachineOperand as follows:Alkis Evlogimenos2003-12-141-1/+1
| | | | | | | | | | | | | | | a) remove opIsUse(), opIsDefOnly(), opIsDefAndUse() b) add isUse(), isDef() c) rename opHiBits32() to isHiBits32(), opLoBits32() to isLoBits32(), opHiBits64() to isHiBits64(), opLoBits64() to isLoBits64(). This results to much more readable code, for example compare "op.opIsDef() || op.opIsDefAndUse()" to "op.isDef()" a pattern used very often in the code. llvm-svn: 10461
* Put all LLVM code into the llvm namespace, as per bug 109.Brian Gaeke2003-11-111-0/+5
| | | | llvm-svn: 9903
* Added LLVM project notice to the top of every C++ source file.John Criswell2003-10-201-0/+7
| | | | | | Header files will be on the way. llvm-svn: 9298
* Const correctness fixesChris Lattner2003-07-261-2/+2

* Fix bug: Jello/2003-06-04-bzip2-bug.llChris Lattner2003-06-051-23/+21

* (1) Added special register class containing (for now) %fsr.Vikram S. Adve2003-05-271-1/+1
| | | | | | | | | | | | | Fixed spilling of %fcc[0-3] which are part of %fsr. (2) Moved some machine-independent reg-class code to class TargetRegInfo from SparcReg{Class,}Info. (3) Renamed MachienOperand::opIsDef to MachineOperand::opIsDefOnly() and related functions and flags. Fixed several bugs where only "isDef" was being checked, not "isDefAndUse". llvm-svn: 6341
* Use a kill, not a dead definition, update commentChris Lattner2003-05-121-5/+4
| | | | llvm-svn: 6131
* * Keep LiveVariable information more up-to-date and consistentChris Lattner2003-05-121-7/+87
| | | | | | | | | * *** Finally mark values that are inputs to PHIs as killed when appropriate. This should make the generated code quite a bit better. For example, the local-ra will not have to spill PHI inputs at the end of predecessor BB's anymore. llvm-svn: 6117
* Fix bug where we could iterate off the end of a basic blockChris Lattner2003-05-121-2/+3
| | | | llvm-svn: 6116
* Fix N^2 algorithmChris Lattner2003-05-121-25/+34
| | | | llvm-svn: 6112
* * Fix several commentsChris Lattner2003-05-121-6/+37
| | | | | | * Update LiveVar info better, fixing bug: Jello/2003-05-11-PHIRegAllocBug.ll llvm-svn: 6110
* Fix problems with empty basic blocksChris Lattner2003-01-161-10/+14

* Rename MachineInstrInfo -> TargetInstrInfoChris Lattner2003-01-141-1/+1
