* Clean up a lot of the code I added yesterday by exposing the IntrinsicLoweringChris Lattner2003-12-284-15/+17
| | | | | | | implementation from the TargetMachine directly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10636 91177308-0d34-0410-b5e6-96231b3b80d8
* Add coalescing to register allocator. A hint is added to each intervalAlkis Evlogimenos2003-12-282-0/+2
| | | | | | | | | | | | which denotes the register we would like to be assigned to (virtual or physical). In register allocation, if this hint exists and we can map it to a physical register (it is either a physical register or it is a virtual register that already got assigned to a physical one) we use that register if it is available instead of a random one in the free pool. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10634 91177308-0d34-0410-b5e6-96231b3b80d8

* Change interface of MachineOperand as follows:Alkis Evlogimenos2003-12-141-20/+16
| | | | | | | | | | | | | | | | 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
