Chris Lattner 2926869b4a Fix a long-standing wart in the code generator: two-address instruction lowering ... actually *removes* one of the operands, instead of just assigning both operands the same register. This make reasoning about instructions unnecessarily complex, because you need to know if you are before or after register allocation to match up operand #'s with the target description file. Changing this also gets rid of a bunch of hacky code in various places. This patch also includes changes to fold loads into cmp/test instructions in the X86 backend, along with a significant simplification to the X86 spill folding code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@30108 91177308-0d34-0410-b5e6-96231b3b80d8		2006-09-05 02:12:02 +00:00
