Fix issue with the Fortran front-end when mapping arrays: when creating the data MEM_REF for the map clause, there was a convention of casting the referencing pointer to 'c_char *' by fold_convert (build_pointer_type (char_type_node), ptr). This causes the alignment passed to the libgomp runtime for array data hardwared to '1', and causes alignment errors on the offload target. This patch fixes this by removing the char_type_node pointer converts, and adding gcc_asserts to ensure POINTER_TYPE_P (TREE_TYPE (ptr)). PR fortran/90030 gcc/fortran/ChangeLog: * trans-openmp.c (gfc_omp_finish_clause): Remove fold_convert to pointer to char_type_node, add gcc_assert of POINTER_TYPE_P. (gfc_trans_omp_array_section): Likewise. (gfc_trans_omp_clauses): Likewise. gcc/testsuite/ChangeLog: * gfortran.dg/goacc/finalize-1.f: Adjust scan test. * gfortran.dg/gomp/affinity-clause-1.f90: Likewise. * gfortran.dg/gomp/affinity-clause-5.f90: Likewise. * gfortran.dg/gomp/defaultmap-4.f90: Likewise. * gfortran.dg/gomp/defaultmap-5.f90: Likewise. * gfortran.dg/gomp/defaultmap-6.f90: Likewise. * gfortran.dg/gomp/map-3.f90: Likewise. * gfortran.dg/gomp/pr78260-2.f90: Likewise. * gfortran.dg/gomp/pr78260-3.f90: Likewise. libgomp/ChangeLog: * testsuite/libgomp.oacc-fortran/pr90030.f90: New test. * testsuite/libgomp.fortran/pr90030.f90: New test. |

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
