Richard Henderson 2911e9b95f tcg/optimize: Fix sign_mask for logical right-shift 
The 'sign' computation is attempting to locate the sign bit that has
been repeated, so that we can test if that bit is known zero.  That
computation can be zero if there are no known sign repetitions.

Fixes: 93a967fbb5 ("tcg/optimize: Propagate sign info for shifting")

README 

This directory contains various interesting guest programs for
regression testing. Tests are either multi-arch, meaning they can be
built for all guest architectures that support linux-user executable,
or they are architecture specific.

CRIS
====
The testsuite for CRIS is in tests/tcg/cris.  You can run it
with "make test-cris".
