* Don't include <map> in Pass.h, which doesn't need it. This requiresDan Gohman2008-03-211-0/+1
| | | | | | adding <map> to many files that actually do need it. llvm-svn: 48667
* Rename MRegisterInfo to TargetRegisterInfo.Dan Gohman2008-02-101-4/+4
| | | | llvm-svn: 46930
* rename TargetInstrDescriptor -> TargetInstrDesc.Chris Lattner2008-01-071-2/+2
| | | | | | | Make MachineInstr::getDesc return a reference instead of a pointer, since it can never be null. llvm-svn: 45695
* Rename MachineInstr::getInstrDescriptor -> getDesc(), which reflectsChris Lattner2008-01-071-3/+2
| | | | | | | | | | | | | | | that it is cheap and efficient to get. Move a variety of predicates from TargetInstrInfo into TargetInstrDescriptor, which makes it much easier to query a predicate when you don't have TII around. Now you can use MI->getDesc()->isBranch() instead of going through TII, and this is much more efficient anyway. Not all of the predicates have been moved over yet. Update old code that used MI->getInstrDescriptor()->Flags to use the new predicates in many places. llvm-svn: 45674
* Move some more instruction creation methods from RegisterInfo into InstrInfo.Owen Anderson2008-01-011-2/+5
| | | | llvm-svn: 45484
* Rename SSARegMap -> MachineRegisterInfo in keeping with the idea Chris Lattner2007-12-311-11/+11
| | | | | | | | | | | | | | that "machine" classes are used to represent the current state of the code being compiled. Given this expanded name, we can start moving other stuff into it. For now, move the UsedPhysRegs and LiveIn/LoveOuts vectors from MachineFunction into it. Update all the clients to match. This also reduces some needless #includes, such as MachineModuleInfo from MachineFunction. llvm-svn: 45467
* Remove attribution from file headers, per discussion on llvmdev.Chris Lattner2007-12-291-2/+2

* Use 'static const char' instead of 'static const int'.Devang Patel2007-05-021-2/+2
| | | | | | | Due to darwin gcc bug, one version of darwin linker coalesces static const int, which defauts PassID based pass identification. llvm-svn: 36652

* Fix a long-standing wart in the code generator: two-address instruction loweringChris Lattner2006-09-051-5/+1
| | | | | | | | | | | | | | | actually *removes* one of the operands, instead of just assigning both operands the same register. This make reasoning about instructions unnecessarily complex, because you need to know if you are before or after register allocation to match up operand #'s with the target description file. Changing this also gets rid of a bunch of hacky code in various places. This patch also includes changes to fold loads into cmp/test instructions in the X86 backend, along with a significant simplification to the X86 spill folding code. llvm-svn: 30108

* Change interface of MachineOperand as follows:Alkis Evlogimenos2003-12-141-2/+2
| | | | | | | | | | | | | | | 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
