adds assertions that check to make sure every operand gets emitted.

9cd4e3429e Completely eliminate def&use operands. Now a register operand is EITHER a 
def operand or a use operand.

 2006-09-05 02:31:13 +00:00
Chris Lattner
59a4d8dfcd 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.
