* Adjust to new TargetMachine interfaceChris Lattner2004-06-021-4/+4
| | | | llvm-svn: 13956
* Make dense maps keyed on physical registers smallerusingAlkis Evlogimenos2004-02-151-1/+1
| | | | | | | | | | MRegisterInfo::getNumRegs() instead of MRegisterInfo::FirstVirtualRegister. Also use MRegisterInfo::is{Physical,Virtual}Register where appropriate. llvm-svn: 11477
* Allow for fixed objects to reside in the local area, and if they don't to notChris Lattner2004-02-151-6/+13

* Change MachineBasicBlock's vector of MachineInstr pointers into anAlkis Evlogimenos2004-02-121-12/+13
| | | | | | | | | 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 Lattner2004-02-101-5/+5

* Eliminate users of MachineOperand::isPhysicalRegisterChris Lattner2004-02-101-1/+2
| | | | llvm-svn: 11278
* Change interface of MachineOperand as follows:Alkis Evlogimenos2003-12-141-2/+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
* Change MRegisterDesc::AliasSet, TargetInstrDescriptor::ImplicitDefsAlkis Evlogimenos2003-10-081-3/+6
| | | | | | | | | | | | | | | | | | | | | 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
* Factory methods for FunctionPasses now return type FunctionPass *.Brian Gaeke2003-08-131-1/+1

* (1) Added special register class containing (for now) %fsr.Vikram S. Adve2003-05-271-1/+2
| | | | | | | | | | | | | 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
