2007-11-27 Paul Thomas <pault@gcc.gnu.org> PR fortran/29389 *resolve.c (resolve_ordinary_assign): Use find_sym_in_expr to test if a temporary should be written for a vector subscript on the lhs. PR fortran/33850 * restore.c (pure_stmt_function): Add prototype and new function. Calls impure_stmt_fcn. (pure_function): Call it. (impure_stmt_fcn): New function. * expr.c (gfc_traverse_expr): Call *func for all expression types, not just variables. Add traversal of character lengths, iterators and component character lengths and arrayspecs. (expr_set_symbols_referenced): Return false if not a variable. * trans-stmt.c (forall_replace, forall_restore): Ditto. * resolve.c (forall_index): Ditto. (sym_in_expr): New function. (find_sym_in_expr): Rewrite to traverse expression calling sym_in_expr. *trans-decl.c (expr_decls): New function. (generate_expr_decls): Rewrite to traverse expression calling expr_decls. *match.c (check_stmt_fcn): New function. (recursive_stmt_fcn): Rewrite to traverse expression calling check_stmt_fcn. 2007-11-27 Paul Thomas <pault@gcc.gnu.org> PR fortran/29389 * gfortran.dg/stfunc_6.f90: New test.
