2024-12-03 Paul Thomas <pault@gcc.gnu.org> gcc/fortran PR fortran/102689 * trans-array.cc (get_array_ref_dim_for_loop_dim): Use the arg1 class container carried in ss->info as the seed for a lhs in class valued transformational intrinsic calls that are not the rhs of an assignment. Otherwise, the lhs variable expression is taken from the loop chain. For this latter case, the _vptr and _len fields are set. (gfc_trans_create_temp_array): Use either the lhs expression seeds to build a class variable that will take the returned descriptor as its _data field. In the case that the arg1 expr. is used, 'atmp' must be marked as unused, a typespec built with the correct rank and the _vptr and _len fields set. The element size is provided for the temporary allocation and to set the descriptor span. (gfc_array_init_size): When an intrinsic type scalar expr3 is used in allocation of a class array, use its element size in the descriptor dtype. * trans-expr.cc (gfc_conv_class_to_class): Class valued transformational intrinsics return the pointer to the array descriptor as the _data field of a class temporary. Extract directly and return the address of the class temporary. (gfc_conv_procedure_call): store the expression for the first argument of a class valued transformational intrinsic function in the ss info class_container field. Later, use its type as the element type in the call to gfc_trans_create_temp_array. (fcncall_realloc_result): Add a dtype argument and use it in the descriptor, when available. (gfc_trans_arrayfunc_assign): For class lhs, build a dtype with the lhs rank and the rhs element size and use it in the call to fcncall_realloc_result. gcc/testsuite/ PR fortran/102689 * gfortran.dg/class_transformational_1.f90: New test for class- valued reshape. * gfortran.dg/class_transformational_2.f90: New test for other class_valued transformational intrinsics. |

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.
