Subject: [Bug tree-optimization/41305]  New: ICE with -O3 -floop-interchange
Date: Tue, 08 Sep 2009 09:16:00 -0000	[thread overview]
Message-ID: <bug-41305-87@http.gcc.gnu.org/bugzilla/> (raw)

[-- Warning: decoded text below may be mangled, UTF-8 assumed --]
[-- Attachment #1: Type: text/plain, Size: 1079 bytes --]

The following testcase ICEs on x86_64-linux on branches/gcc-4_4-branch with -O3
-floop-interchange:
Unable to coalesce ssa_names 99 and 106 which are marked as MUST COALESCE.
xi$data_$size__99(ab) and  xi$data_$size__106(ab)
/tmp/rh520785.ii: In function ‘void foo(int)’:
/tmp/rh520785.ii:321: internal compiler error: SSA corruption
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
Couldn't reproduce this on the trunk, but that doesn't mean the bug isn't
latent there.  Doesn't reproduce without -floop-interchange, so I assume it is
graphite which is at fault here.
