* 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

* 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

* Do not use MachineOperand::isVirtualRegister either!Chris Lattner2004-02-101-1/+1
| | | | llvm-svn: 11283
* 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

| | | | | | | | | | | | | | | | | | | | | and TargetInstrDescriptor::ImplicitUses to always point to a null terminated array and never be null. So there is no need to check for pointer validity when iterating over those sets. Code that looked like: if (const unsigned* AS = TID.ImplicitDefs) { for (int i = 0; AS[i]; ++i) { // use AS[i] } } was changed to: for (const unsigned* AS = TID.ImplicitDefs; *AS; ++AS) { // use *AS } llvm-svn: 8960
