re PR fortran/29389 (Statement functions are not recognized as pure when they are)
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.
