Subject: [Bug c++/56493] Performance regression in google dense hashmap
Date: Sun, 16 Jun 2013 10:25:00 -0000	[thread overview]

gcc49-pr56493.patch

Untested patch that in the FE restores the performance on the simplified
testcase.  Haven't tried the original.  Of course, having this optimization be
performed in GIMPLE will be much more worthwhile, but likely not backportable.
