Bug ID: 61768
Summary: Fortran compiler goes into infinite loop while
compiling SPEC2000 applu.f
Product: gcc
Version: 4.10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: kuganv at linaro dot org
arm-linux-gnueabihf-gfortran -c -floop-interchange applu.f goes into infinite
loop.
It goes into infinite loop in
isl_vec_mat_product,
....
while ((off = row_first_non_zero(left->row+first,
left->n_row-first, row)) != -1) {
....
Happens in trunk with cloog-0.18.1.tar.gz, isl-0.12.2.tar.bz2,
gmp-4.3.2.tar.bz2, mpc-0.8.1.tar.gz and mpfr-2.4.2.tar.bz2.
minimal Fortran code to reproduce this should contain subroutine setbv and
exact.
gcc -v output:
arm-none-linux-gnueabi-gfortran -v
Using built-in specs.

Such code, or better, a reduced reproducer, should be provided. From comment 0,
it seems that this PR a graphite problem on arm processor, thus not a gfortran
bug.
