Bob Wilson 4711d5cda3 Remove the rest of the *_sfp Neon instruction patterns. ... Use the same COPY_TO_REGCLASS approach as for the 2-register *_sfp instructions. This change made a big difference in the code generated for the CodeGen/Thumb2/cross-rc-coalescing-2.ll test: The coalescer is still doing a fine job, but some instructions that were previously moved outside the loop are not moved now. It's using fewer VFP registers now, which is generally a good thing, so I think the estimates for register pressure changed and that affected the LICM behavior. Since that isn't obviously wrong, I've just changed the test file. This completes the work for Radar 8711675. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121730 91177308-0d34-0410-b5e6-96231b3b80d8		2010-12-13 23:02:37 +00:00
