* Subject: 27% regression of gcc 4.3 performance on cpu2k6/calculix
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-linux.
Regression is caused by mem-ssa

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=default 50> ?
Diego up'd the default from 10 to 50 because one (or more) of the
(Fortran) Polyhedron benchmarks showed a dramatic performance regression.

Regression is caused by mem-ssa merge 12/12/2006 (revision 119760).
