It makes sense. I will update the patch.
Thanks

Hi,
By checking the object files of SPECint, I found that two kinds of
compare/move can't be combined to "mr." pattern as there is no register
link between them. The patch adds two peephole2 patterns for them.
Bootstrapped and tested on powerpc64-linux BE and LE with no regressions.
Thanks
Gu
