* gcov-io.c (gcov_read_words): Don't call memmove if excess is 0.
* data-streamer-in.c (streamer_read_hwi): Shift UHWI 1 instead of
HWI 1 and negate the unsigned value.
* expmed.c (expand_sdiv_pow2): For modes wider than word always
use AND instead of shift.
* wide-int-print.cc (print_decs): Negate UHWI instead of HWI.
c-family/
* c-ada-spec.c (dump_ada_nodes): Don't call qsort if
comments->count <= 1, as comments->entries might be NULL.
