Sanjay Patel c3aa82cda9 [InstCombine] try harder to form rotate (funnel shift) (PR20750) ... We have a similar match for patterns ending in a truncate. This should be ok for all targets because the default expansion would still likely be better from replacing 2 'and' ops with 1. Attempt to show the logic equivalence in Alive (which doesn't currently have funnel-shift in its vocabulary AFAICT): %shamt = zext i8 %i to i32 %m = and i32 %shamt, 31 %neg = sub i32 0, %shamt %and4 = and i32 %neg, 31 %shl = shl i32 %v, %m %shr = lshr i32 %v, %and4 %or = or i32 %shr, %shl => %a = and i8 %i, 31 %shamt2 = zext i8 %a to i32 %neg2 = sub i32 0, %shamt2 %and4 = and i32 %neg2, 31 %shl = shl i32 %v, %shamt2 %shr = lshr i32 %v, %and4 %or = or i32 %shr, %shl https://rise4fun.com/Alive/V9r llvm-svn: 360605		2019-05-13 17:28:19 +00:00
