[google] Prune -fopt-info output
- From: tejohnson at google dot com (Teresa Johnson)

- Subject: [google] Prune -fopt-info output
This patch reduces the copious -fopt-info output by making the default for
-fopt-info to be -fopt-info=optimized instead of -fopt-info=all. It also
changes most of the vectorizer messages to use MSG_NOTE instead of
MSG_OPTIMIZED_LOCATION.
Reduced the output of -fopt-info for one application by >75%. Testing in
progress.
Ok for google/4_8 if testing passes?
Thanks, Teresa
