The following series of patches improves usage of the risbg and
risbgn instructions on s390/s390x. The patches have been
regression tested on s390 and s390x and pass the Spec2006
testsuite without any negative effects.
Patch 1 introduces a new mode attribute to simplify some
instruction patterns.
Patch 2 enables wraparound of bit ranges and rewrites portion of
the bitrange calculation code to do so.
Patch 3 adds new patterns and tests based on the first two patches
to make better use of the risbg and risbgn instructions.
Please check the individual Changelogs for details.
Ciao
Dominik ^_^ ^_^
