Buglet in cris_preferred_reload_class, incidental, apparently
without effect at least regarding failing test-cases. A class
disjunct from the input was returned as "preferred". It could
arguably be gcc_asserted as a sanity-check by the caller that
the returned class is a subset of the original class. ...and I
guess I'll add such a gcc_assert *inside*
cris_preferred_reload_class. Later. No regressions, cris-elf
and crisv32-elf. Committed.
gcc:
* config/cris/cris.c (cris_preferred_reload_class):
Don't return GENERAL_REGS as preferred to MOF_SRP_REGS.
