PR fortran/19239 * Makefile.in (fortran/trans-expr.o): Depend on dependency.h. * dependency.h (gfc_ref_needs_temporary_p): Declare. * dependency.c (gfc_ref_needs_temporary_p): New function. (gfc_check_fncall_dependency): Use it instead of inlined check. By so doing, take advantage of the fact that character substrings within an array reference also need a temporary. * trans.h (GFC_SS_VECTOR): Adjust comment. * trans-array.c (gfc_free_ss): Remove GFC_SS_VECTOR case. (gfc_set_vector_loop_bounds): New function. (gfc_add_loop_ss_code): Call it after evaluating the subscripts of a GFC_SS_SECTION. Deal with the GFC_SS_VECTOR case by evaluating the vector expression and caching its descriptor for use within the loop. (gfc_conv_array_index_ref, gfc_conv_vector_array_index): Delete. (gfc_conv_array_index_offset): Handle scalar, vector and range dimensions as separate cases of a switch statement. In the vector case, use the loop variable to calculate a vector index and use the referenced element as the dimension's index. Perform bounds checking on this final index. (gfc_conv_section_upper_bound): Return null for vector indexes. (gfc_conv_section_startstride): Give vector indexes a start value of 0 and a stride of 1. (gfc_conv_ss_startstride): Adjust for new GFC_SS_VECTOR representation. (gfc_conv_expr_descriptor): Expand comments. Generalize the handling of the !want_pointer && !direct_byref case. Use gfc_ref_needs_temporary_p to decide whether the variable case needs a temporary. (gfc_walk_variable_expr): Handle DIMEN_VECTOR by creating a GFC_SS_VECTOR index. * trans-expr.c: Include dependency.h. (gfc_trans_arrayfunc_assign): Fail if the target needs a temporary. 2005-09-09 Richard Sandiford <richard@codesourcery.com> PR fortran/21104 * trans.h (gfc_interface_sym_mapping, gfc_interface_mapping): Moved from trans-expr.c. (gfc_init_interface_mapping, gfc_free_interface_mapping) (gfc_add_interface_mapping, gfc_finish_interface_mapping) (gfc_apply_interface_mapping): Declare. * trans-array.h (gfc_set_loop_bounds_from_array_spec): Declare. (gfc_trans_allocate_temp_array): Add pre and post block arguments. * trans-array.c (gfc_set_loop_bounds_from_array_spec): New function. (gfc_trans_allocate_array_storage): Replace loop argument with separate pre and post blocks. (gfc_trans_allocate_temp_array): Add pre and post block arguments. Update call to gfc_trans_allocate_array_storage. (gfc_trans_array_constructor, gfc_conv_loop_setup): Adjust for new interface to gfc_trans_allocate_temp_array. * trans-expr.c (gfc_interface_sym_mapping, gfc_interface_mapping): Moved to trans.h. (gfc_init_interface_mapping, gfc_free_interface_mapping) (gfc_add_interface_mapping, gfc_finish_interface_mapping) (gfc_apply_interface_mapping): Make extern. (gfc_conv_function_call): Build an interface mapping for array return values too. Call gfc_set_loop_bounds_from_array_spec. Adjust call to gfc_trans_allocate_temp_array so that code is added to SE rather than LOOP. From-SVN: r104077 |

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file 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*.
