* Change MRegisterDesc::AliasSet, TargetInstrDescriptor::ImplicitDefsAlkis Evlogimenos2003-10-081-15/+19
| | | | | | | | | | | | | | | | | | | | | 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
* (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
* * Keep the BBMap around as long as the pass is liveChris Lattner2003-05-121-8/+23
| | | | | | | * Change getVarInfo to take real virtual register numbers and offset them itself. This has caused me so much grief, it's not even funny. llvm-svn: 6115
* Add a vector to keep track of which registers are allocatable. Remove FIXMEsChris Lattner2003-05-071-14/+38
