--- Comment #5 from Matt Hargett <matt at use dot net> 2012-06-11 20:02:41 UTC --- Got rid of graphite options, it made no difference. I reduced the original test from the suite and attached it's source, preprocessor output from 4.6 and 4.7 (no major difference), and callgrind output. To keep things simple, I'm just using -O3 and -fwhole-program. According to callgrind, 4.7's instruction references went up by 60% and D1 misses went up by 15% at -O3 versus 4.6 at -O3. Let me know if you need any more information to continue triaging. Thanks!
