version.c: Bump for snapshot.
* version.c: Bump for snapshot. * expmed.c (expand_divmod): Make op1_is_pow2 depend on unsignedp for negative constants. Promote EXACT_DIV_EXPR to TRUNC_DIV_EXPR when op1_is_pow2. * final.c (shorten_branches): During first pass, assume worst possible alignment for ADDR_VEC and ADDR_VEC_DIFF insns. * Makefile.in (distclean): Remove various things left around by running the testsuite.
