This patch updates how the OpenACC tile clause is handled in the Fortran
FE to match it's behavior in C/C++. Specifically, the tile clause now
errors on negative integer arguments, instead of emitting a warning.
Is this OK for trunk?
Thanks,
Cesar

Subject: [PATCH] [OpenACC] update gfortran's tile clause error handling
2018-XX-YY Cesar Philippidis
gcc/fortran/
* openmp.c (resolve_positive_int_expr): Promote the warning to an
error.
gcc/testsuite/
* gfortran.dg/goacc/loop-2.f95: Change expected tile clause
warnings to errors.
* gfortran.dg/goacc/loop-5.f95: Likewise.
* gfortran.dg/goacc/sie.f95: Likewise.
* gfortran.dg/goacc/tile-1.f90: New test.
* gfortran.dg/goacc/tile-2.f90: New test.
