r216433 - in /branches/google/gcc-4_9/gcc: opts...

Author: tejohnson
Date: Sun Oct 19 00:17:05 2014
New Revision: 216433

URL: https://gcc.gnu.org/viewcvs?rev=216433&root=gcc&view=rev
Log:
Disabling devirtualization reduces code size, both for instrumentation (because
many more virtual functions are kept longer and therefore instrumented) and for
normal optimization.
