Summary: ICE in vect_enhance_data_refs_alignment when building
fma3d
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: pthaugen@gcc.gnu.org
CC: rguenth@gcc.gnu.org

testcase
Looks like the fix for PR45720 (rev165832) causes an ICE when trying to build
CPU2000 benchmark fma3d. Benchmark file is fma1.f90, reduced testcase is
attatched.
> gfortran -c -O2 -ftree-vectorize -mcpu=power7 err.f90
err.f90: In function `spot_weld_initialization':
err.f90:1:0: internal compiler error: in vect_enhance_data_refs_alignment, at
tree-vect-data-refs.c:1550
