------- Comment #4 from rguenth at gcc dot gnu dot org 2008-09-18 12:55 -------
Confirmed. For 4.4 the following was done:
2008-08-20 Richard Guenther <rguenther@suse.de>
* passes.c (init_optimization_passes): Move the second
forwprop pass before alias computation. Remove the second
DCE pass. Remove the first dominator and phi copy/const
prop passes.
2008-08-19 Richard Guenther <rguenther@suse.de>
* passes.c (init_optimization_passes): Exchange store-ccp
with a ccp pass.
2008-08-18 Richard Guenther <rguenther@suse.de>
* passes.c (init_optimization_passes): Remove cleanup_cfg1,
sdse1 and addressables2 passes. Replace dce1 with cddce1.
Move call_cdce before build_alias. Move copyrename2,
cunrolli and ccp2 beafore build_alias. Re-add addressable2
right after final inlining.
unassigning for now.
