Kyle Butt 77f7a2b7a8 Codegen: [PPC] Fix PPCVSXFMAMutate to handle duplicates. ... The purpose of PPCVSXFMAMutate is to elide copies by changing FMA forms on PPC. %vreg6<def> = COPY %vreg96 %vreg6<def,tied1> = XSMADDASP %vreg6<tied0>, %vreg5<kill>, %vreg7 ;v6 = v6 + v5 * v7 is replaced by %vreg5<def,tied1> = XSMADDMSP %vreg5<tied0>, %vreg7, %vreg96 ;v5 = v5 * v7 + v96 This was broken in the case where the target register was also used as a multiplicand. Fix this case by checking for it and replacing both uses with the copied register. %vreg6<def> = COPY %vreg96 %vreg6<def,tied1> = XSMADDASP %vreg6<tied0>, %vreg5<kill>, %vreg6 ;v6 = v6 + v5 * v6 is replaced by %vreg5<def,tied1> = XSMADDMSP %vreg5<tied0>, %vreg96, %vreg96 ;v5 = v5 * v96 + v96 llvm-svn: 259617		2016-02-03 01:41:09 +00:00
