3799 * simplify.c (gfc_simplify_char): Use UCHAR_MAX instead of literal
3801 (gfc_simplify_ichar): Get the result from unsinged char and in the
3802 range 0 to UCHAR_MAX instead of CHAR_MIN to CHAR_MAX.
3804 2006-01-08 Erik Edelmann <eedelman@gcc.gnu.org>
3807 * resolve.c (resolve_fntype): Check that PUBLIC functions
3808 aren't of PRIVATE type.
3810 2006-01-07 Tobias Schl"uter <tobias.schlueter@physik.uni-muenchen.de>
3812 * decl.c (gfc_match_function_decl): Correctly error out in case of
3813 omitted function argument list.
3815 2006-01-07 Paul Thomas <pault@gcc.gnu.org>
3818 * trans-array.c (gfc_reverse_ss): Remove static attribute.
3819 (gfc_walk_elemental_function_args): Replace gfc_expr * argument for
3820 the function call with the corresponding gfc_actual_arglist*. Change
3822 (gfc_walk_function_expr): Call to gfc_walk_elemental_function_args
3823 now requires the actual argument list instead of the expression for
3825 * trans-array.h: Modify the prototype for gfc_walk_elemental_function_args
3826 and provide a prototype for gfc_reverse_ss.
3827 * trans-stmt.h (gfc_trans_call): Add the scalarization code for the case
3828 where an elemental subroutine has array valued actual arguments.
3834 * resolve.c (check_assumed_size_reference): New function to check for upper
3835 bound in assumed size array references.
3836 (resolve_assumed_size_actual): New function to do a very restricted scan
3837 of actual argument expressions of those procedures for which incomplete
3838 assumed size array references are not allowed.
3839 (resolve_function, resolve_call): Switch off assumed size checking of
3840 actual arguments, except for elemental procedures and intrinsic
3841 inquiry functions, in some circumstances.
3842 (resolve_variable): Call check_assumed_size_reference.
3844 2006-01-05 Jerry DeLisle <jvdelisle@gcc.gnu.org>
3847 * io.c (next_char_not_space): New function that returns the next
3848 character that is not white space.
3849 (format_lex): Use the new function to skip whitespace within
3852 2006-01-05 Erik Edelmann <eedelman@gcc.gnu.org>
3855 * expr.c (gfc_expr_set_symbols_referenced): New function.
3856 * gfortran.h: Add a function prototype for it.
3857 * resolve.c (resolve_function): Use it for
3858 use associated character functions lengths.
3859 * expr.c, gfortran.h, resolve.c: Updated copyright years.
3861 2006-01-03 Steven G. Kargl <kargls@comcast.net>
3864 * resolve.c (resolve_forall_iterators): Check for scalar variables;
3865 Check stride is nonzero.
3867 2006-01-02 Steven G. Kargl <kargls@comcast.net>
3870 * parse.c (next_free): Check for whitespace after the label.
3871 * match.c (gfc_match_small_literal_int): Initialize cnt variable.
