Chris Lattner f38df04c3a Fix a problem that Nate noticed, where spill code was not getting coallesced ... with copies, leading to code like this: lwz r4, 380(r1) or r10, r4, r4 ;; Last use of r4 By teaching the PPC backend how to fold spills into copies, we now get this code: lwz r10, 380(r1) wow. :) This reduces a testcase nate sent me from 1505 instructions to 1484. Note that this could handle FP values but doesn't currently, for reasons mentioned in the patch git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23298 91177308-0d34-0410-b5e6-96231b3b80d8		2005-09-09 21:46:49 +00:00
