40% performance regression SPEC2006/leslie3d on gcc-4_2-branch

Hello, Daniel It looks like your changeset listed bellow makes performance regression ~40% on SPEC2006/leslie3d. I will try to create minimal test for this issue this week and update you in any case. Feel free to ask if any question. FYI: Hardware is Core2Duo. Compiler config Target: x86_64-re

Re: 27% regression of gcc 4.3 performance on cpu2k6/calculix

Hi! I create test to reproduce issue with cpu2006/454.calculix See attached. File e_c3d.f contains cutted subroutine from calculix. tr535.f main entry point of the test. you can use go-script as a reference how i get these results. find_stall.pl script which find problem instruction combinations.
