2016-02-26powerpc: Handle DImode rotatert implemented with rlwinm (PR69946)Segher Boessenkool4-2/+54
Some DImode rotate-right-and-mask can be implemented best with a rlwinm instruction: those that could be a lshiftrt instead of a rotatert, while the mask is not right-aligned. Why the rotate in the testcase is not optimised to a plain shift is another question, but we need to handle it here anyway. We compute the shift amount for a 64-bit rotate. This is 32 too high in this case; if we print using %h that is masked out (and this doesn't silently let through invalid instructions, everything is checked by rs6000_is_valid_shift_mask which is much more thorough).

This fixes a wrong code generation problem with the splitters introduced with that patch: https://gcc.gnu.org/ml/gcc-patches/2015-07/msg01840.html The target operand is used as temporary. This fails if it matches the source of the left shift which is read after writing the temporary. Thanks to Dominik for debugging it and thanks to Richard for the fix!
