Name: narrow_shift Pre: C1 < 8 %zx = zext i8 %x to i32 %l = lshr i32 %zx, C1 => %narrowC = trunc i32 C1 to i8 %ns = lshr i8 %x, %narrowC %l = zext i8 %ns to i32 http://rise4fun.com/Alive/jIV This isn't directly applicable to PR34046 as written, but we need to have more narrowing folds like this to be sure that rotate patterns are recognized. llvm-svn: 310060 |
