From 4e2044d68d06c85761edf7510e23ea06c9279fdb Mon Sep 17 00:00:00 2001 From: Jakub Jelinek Date: Wed, 21 Dec 2016 17:16:20 +0100 Subject: re PR fortran/78866 (ICE in gimplify_adjust_omp_clauses_1, at gimplify.c:8721) PR fortran/78866 * openmp.c (resolve_omp_clauses): Diagnose assumed size arrays in OpenMP map, to and from clauses. * trans-openmp.c: Include diagnostic-core.h, temporarily redefining GCC_DIAG_STYLE to __gcc_tdiag__. (gfc_omp_finish_clause): Diagnose implicitly mapped assumed size arrays. * gfortran.dg/gomp/map-1.f90: Add expected error. * gfortran.dg/gomp/pr78866-1.f90: New test. * gfortran.dg/gomp/pr78866-2.f90: New test.
