Hans-Peter Nilsson - July 16, 2012, 3:50 a.m.
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.

	* config/cris/cris.c (cris_preferred_reload_class):
	Don't return GENERAL_REGS as preferred to MOF_SRP_REGS.

brgds, H-P
