--- Comment #7 from Martin Reinecke <mar...@mpa-garching.mpg.de> 2011-01-19 14:16:18 UTC --- OK, I located the problematic commit, at least on the 4.5 branch: it's revision number 167492 (fix for PR tree-optimization/46806). Between revisions 167491 and 167492 the CPU time for the testcase2.c jumps from 4.7s to 5.4s. Do you think that anything can be done about this regression?
