[PATCH 3/3] Fix integer overflow in stats of GIMPLE statements.

[marxin]

gcc/ChangeLog:

2018-01-12  Martin Liska  <mli...@suse.cz>

        * gimple.c (gimple_alloc_counts): Use uint64_t instead of int.
        (gimple_alloc_sizes): Likewise.
        (dump_gimple_statistics): Use PRIu64 in printf format.
        * gimple.h: Change uint64_t to int.
