Sometimes combine wants to do a move in CCFPmode, but we don't currently handle moves in any CC mode other than CCmode. Fix that oversight.
Tested on powerpc64-linux {-m32,-m64}. Committing to trunk. Segher 2019-11-10 Segher Boessenkool <seg...@kernel.crashing.org> * config/rs6000/rs6000.md (CC_any): New mode iterator. (*movcc_internal1): Rename to... (*movcc_<mode> for CC_any): ... this. Support moves of all CC modes. --- gcc/config/rs6000/rs6000.md | 16 +++++++++------- 1 file changed, 9 insertions(+), 7 deletions(-) diff --git a/gcc/config/rs6000/rs6000.md b/gcc/config/rs6000/rs6000.md index 1944abf..0cdfdef 100644 --- a/gcc/config/rs6000/rs6000.md +++ b/gcc/config/rs6000/rs6000.md @@ -7220,13 +7220,15 @@ (define_expand "movcc" "" "") -(define_insn "*movcc_internal1" - [(set (match_operand:CC 0 "nonimmediate_operand" - "=y,x,?y,y,r,r,r,r, r,*c*l,r,m") - (match_operand:CC 1 "general_operand" - " y,r, r,O,x,y,r,I,*h, r,m,r"))] - "register_operand (operands[0], CCmode) - || register_operand (operands[1], CCmode)" +(define_mode_iterator CC_any [CC CCUNS CCEQ CCFP]) + +(define_insn "*movcc_<mode>" + [(set (match_operand:CC_any 0 "nonimmediate_operand" + "=y,x,?y,y,r,r,r,r, r,*c*l,r,m") + (match_operand:CC_any 1 "general_operand" + " y,r, r,O,x,y,r,I,*h, r,m,r"))] + "register_operand (operands[0], <MODE>mode) + || register_operand (operands[1], <MODE>mode)" "@ mcrf %0,%1 mtcrf 128,%1 -- 1.8.3.1
