When compiling the aermod.f90 from the Polyhedron 2005 benchmarks with gfortran
using either...

gfortran -ffast-math -floop-block -O2 -fgraphite aermod.f90

or

gfortran -ffast-math -O2 -floop-strip-mine -fgraphite aermod.f90

results in the compiler error...

aermod.f90: In function ‘vrtcbl’:
aermod.f90:14521: internal compiler error: in instantiate_scev_1, at
tree-scalar-evolution.c:2220
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

This error doesn't occur when the -ffast-math flag is not used.

Hi,

For the first part of the bug:

> aermod.f90:14521: internal compiler error: in instantiate_scev_1, at
> tree-scalar-evolution.c:2220

the bug was introduced by an automatic rewrite arount TREE_CODE_LENGTH
http://gcc.gnu.org/viewcvs?view=rev&revision=122018

The fix avoids the gcc_assert by returning "unknown scalar evolution".

The second part of the bug was already fixed:
> aermod.f90:8312: internal compiler error: in expand_scalar_variables_expr, at
> graphite.c:3168

I will apply the patch below once it finishes regstrap.

Sebastian
