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

Hi!
There is a huge regression of gcc 4.3 performance detected on
cpu2006/454.calculix benchmark at -O2 optimization level on
x86_64-redhat

Right, calculix is a combined program. Gprof says

Is that possible to extract a smaller testcase?
I'm working on the small reproducer. That would take some time because
of benchmark complexity.

Right, calculix is a combined program. Gprof says the regression is in
e_c3d routine which is 1k lines of Fortran code.
Grigory,
Calculix is a combined C/Fortran program. Did you try to compile the
Fortran parts with --param max-aliased-vops=something higher than the
default 50 ?
Diego up'd the default from 10 to 50 because one (or more) of the
(Fortran) Polyhedron benchmarks showed a dramatic performance
