powerpc: Handle DImode rotatert implemented with rlwinm (PR69946) · d1f2bea5

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).


	PR target/69946
	* config/rs6000/rs6000.c (rs6000_insn_for_shift_mask): Print rlwinm
	shift amount using %h.  Add comment.

S/390: PR69709 Fix risbg splitter · 1d11f7ce

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!

Bootstrapped and regtested on s390x with-arch=z13.
