2007-10-29 Paul Thomas <pault@gcc.gnu.org> PR fortran/31217 PR fortran/33811 PR fortran/33686 * trans-array.c (gfc_conv_loop_setup): Send a complete type to gfc_trans_create_temp_array if the temporary is character. * trans-stmt.c (gfc_trans_assign_need_temp): Do likewise for allocate_temp_for_forall_nest. (forall_replace): New function. (forall_replace_symtree): New function. (forall_restore): New function. (forall_restore_symtree): New function. (forall_make_variable_temp): New function. (check_forall_dependencies): New function. (cleanup_forall_symtrees): New function. gfc_trans_forall_1): Add and initialize pre and post blocks. Call check_forall_dependencies to check for all dependencies and either trigger second forall block to copy temporary or copy lval, outside the forall construct and replace all dependent references. After assignment clean-up and coalesce the blocks at the end of the function. * gfortran.h : Add prototypes for gfc_traverse_expr and find_forall_index. expr.c (gfc_traverse_expr): New function to traverse expression and visit all subexpressions, under control of a logical flag, a symbol and an integer pointer. The slave function is caller defined and is only called on EXPR_VARIABLE. (expr_set_symbols_referenced): Called by above to set symbols referenced. (gfc_expr_set_symbols_referenced): Rework of this function to use two new functions above. * resolve.c (find_forall_index): Rework with gfc_traverse_expr, using forall_index. (forall_index): New function used by previous. * dependency.c (gfc_check_dependency): Use gfc_dep_resolver for all references, not just REF_ARRAY. (gfc_dep_resolver): Correct the logic for substrings so that overlapping arrays are handled correctly. 2007-10-29 Paul Thomas <pault@gcc.gnu.org> PR fortran/31217 PR fortran/33811 * gfortran.dg/forall_12.f90: New test.

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*. See http://gcc.gnu.org/bugs.html for how to report bugs usefully.
