X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c10e3d7f2aaf10e3ef6c3ce8ba7cbb3123f62df3;p=gcc.git

aarch64.opt (mverbose-cost-dump): New option.

2016-11-16  Andrew PInski  <apinski@cavium.com>

        * config/aarch64/aarch64.opt (mverbose-cost-dump): New option.
        * config/aarch64/aarch64.c (aarch64_rtx_costs): Use
        flag_aarch64_verbose_cost instead of checking for details dump.
        (aarch64_rtx_costs_wrapper): Likewise.
