Bug ID: 77344
Summary: Internal Compiler Error with arch knl
Product: gcc
Version: 6.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org

Tarball with offending code and GNUmakefile
I have a code that when it is compiled with -march=knl -mtune=knl, causes an
ICE (see output below). It doesn't ICE out with, say -march=haswell
-mtune=intel.
This is with GCC 6.1.0, I haven't tried 6.2.0 yet, but I'll try and get that
built today.
I have to attach a tarball because the offending code depends on other codes to
compile. To test the fault, just run "make". This code does *not* make an
executable as I included just the files necessary to throw the ICE.
(444) $ gfortran -O3 -march=knl -mtune=knl -funroll-loops
-ffixed-line-length-132 -fno-range-check -fPIC -ffpe-trap=zero,overflow
-fbacktrace -falign-commons -save-temps -v -c sorad.F90
Using built-in specs.
