Hal Finkel 47ab8c106f [RegisterCoalescer] Remove copies to reserved registers ... This allows the RegisterCoalescer to join "non-flipped" range pairs with a physical destination register -- which allows the RegisterCoalescer to remove copies like this: <vreg> = something (maybe a load, for example) ... (things that don't use PHYSREG) PHYSREG = COPY <vreg> (with all of the restrictions normally applied by the RegisterCoalescer: having compatible register classes, etc. ) Previously, the RegisterCoalescer handled only the opposite case (copying *from* a physical register). I don't handle the problem fully here, but try to get the common case where there is only one use of <vreg> (the COPY). An upcoming commit to the PowerPC backend will make this pattern much more common on PPC64/ELF systems. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@226071 91177308-0d34-0410-b5e6-96231b3b80d8		2015-01-15 01:25:28 +00:00
