Subject: toplev.c (rest_of_compilation): No longer set reload_completed.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=faa6e5c4103e211e52ea5fd0d7f4cf25ae9624b5;p=gcc.git

toplev.c (rest_of_compilation): No longer set reload_completed.

�
        * toplev.c (rest_of_compilation): No longer set reload_completed.
        * reload1.c (reload): Set it here.  Perform instruction splitting
        after reload has completed if we will be running the scheduler
        again.
