2004-02-10Remove and simplify some of the bewildering collection of isFOORegisterChris Lattner
methods which have strangely different semantics in different backends, and noone knew what any did. Getting rid of these ALSO allows the dependence of MachineInstr.h on MRegisterInfo.h to be removed, which makes me much happier, and probably alkis too. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11287 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-10Eliminate MachineOperand::isPhysicalRegister. The X86 backend should useChris Lattner
MRegisterInfo::isPhysicalRegister(MO.getReg()) and the Sparc backend should use isMachineRegister() git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11279 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-10Simplify condition, this does not change the predicate at all thoughChris Lattner

2004-02-04Modify the two address instruction pass to remove the duplicateAlkis Evlogimenos
operand of the instruction and thus simplify the register allocation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11124 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-03When an instruction like: A += B had both A and B virtual registersAlkis Evlogimenos
spilled, A was loaded from its stack location twice. This fixes the bug. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11093 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-02Revert changes. Will implement this using a different set of primitivesAlkis Evlogimenos

2004-02-02Add MachineOperand::setDef() and MachineOperand::setUse() so that theAlkis Evlogimenos

2003-12-14I wonder how this didn't cause any tests to fail...Alkis Evlogimenos
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10462 91177308-0d34-0410-b5e6-96231b3b80d8
2003-12-14Change interface of MachineOperand as follows:Alkis Evlogimenos
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10461 91177308-0d34-0410-b5e6-96231b3b80d8

2003-08-05Completely eliminate the per-machine-instruction regsUsed set.Chris Lattner
This substantially shrinks the size of each machine instruction, which should make allocation faster and the cache footprint of the machine code lighter.

2003-08-05All callers of these methods actually wanted them to preserve the flags,Chris Lattner
so get rid of the def/use parameters that were getting passed in. **** This now changes the semantics of these methods to preserve the flags, not clobber them! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7602 91177308-0d34-0410-b5e6-96231b3b80d8
