Author: burnus Date: Mon Oct 29 14:13:44 2007 New Revision: 129720 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=129720 Log: 2007-10-29 Paul Thomas <[EMAIL PROTECTED]> 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 <[EMAIL PROTECTED]> PR fortran/31217 PR fortran/33811 * gfortran.dg/forall_12.f90: New test.
