Sorry, can't reproduce any performance degradation between 4.1 and 4.6
on the http://gcc.gnu.org/bugzilla/attachment.cgi?id=26814 testcase (-O3 -m64,
default -mtune=generic):
on i7-2600 4.1 user time is 0m3.833s, 4.6 0m3.411s and 4.7 0m5.102s,
on AMD Barcelona 4.1 user time is 0m8.798s, 4.6 0m5.875s and 4.7 0m5.855s.
