* Reserve ECX and EDI instead of EBX and EDI. Since EBX is a calleeAlkis Evlogimenos2003-12-281-8/+8
| | | | | | | | | saved register it has a longer free range than ECX (which is defined every time there is a fnuction call) which makes ECX a better register to reserve. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10635 91177308-0d34-0410-b5e6-96231b3b80d8
* Add coalescing to register allocator. A hint is added to each intervalAlkis Evlogimenos2003-12-283-2/+30
| | | | | | | | | | | | 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
