Subject: [Bug middle-end/24049] [4.1 regression] compiler error: Segmentation fault In function 'DESX_CBCUpdate'
Date: Sat, 24 Sep 2005 20:12:00 -0000 [thread overview]
Message-ID: <20050924201222.32622.qmail@sourceware.org> (raw)
In-Reply-To: <20050924140210.24049.harold@alum.mit.edu>
------- Additional Comments From pinskia at gcc dot gnu dot org 2005-09-24 20:12 -------
This is a very recent regression as it worked with 20050908.
I think it was caused by:
2005-09-17 Richard Henderson <rth@redhat.com>
* tree-pass.h, tree-flow.h, tree-ssa-dce.c: Revert last change.
* tree-ssa-loop.c (pass_vect_dce): Remove.
* passes.c (init_optimization_passes): Add pass_dce as a sub-pass
of pass_vectorize.
The issue is that the scev is not very GC friendly.
