3254 (gfc_simplify_ichar): Get the result from unsinged char and in the

3257 2006-01-08 Erik Edelmann <eedelman@gcc.gnu.org>
3260 * resolve.c (resolve_fntype): Check that PUBLIC functions

3266 omitted function argument list.
3268 2006-01-07 Paul Thomas <pault@gcc.gnu.org>
3271 * trans-array.c (gfc_reverse_ss): Remove static attribute.
3272 (gfc_walk_elemental_function_args): Replace gfc_expr * argument for
3273 the function call with the corresponding gfc_actual_arglist*. Change
3275 (gfc_walk_function_expr): Call to gfc_walk_elemental_function_args
3276 now requires the actual argument list instead of the expression for
3278 * trans-array.h: Modify the prototype for gfc_walk_elemental_function_args
3279 and provide a prototype for gfc_reverse_ss.
3280 * trans-stmt.h (gfc_trans_call): Add the scalarization code for the case
3281 where an elemental subroutine has array valued actual arguments.
3287 * resolve.c (check_assumed_size_reference): New function to check for upper
3288 bound in assumed size array references.
3289 (resolve_assumed_size_actual): New function to do a very restricted scan
3290 of actual argument expressions of those procedures for which incomplete
3291 assumed size array references are not allowed.
3292 (resolve_function, resolve_call): Switch off assumed size checking of
3293 actual arguments, except for elemental procedures and intrinsic
3294 inquiry functions, in some circumstances.
3295 (resolve_variable): Call check_assumed_size_reference.
3297 2006-01-05 Jerry DeLisle <jvdelisle@gcc.gnu.org>
3300 * io.c (next_char_not_space): New function that returns the next
3301 character that is not white space.
3302 (format_lex): Use the new function to skip whitespace within
3305 2006-01-05 Erik Edelmann <eedelman@gcc.gnu.org>
3308 * expr.c (gfc_expr_set_symbols_referenced): New function.
3309 * gfortran.h: Add a function prototype for it.
3310 * resolve.c (resolve_function): Use it for
3311 use associated character functions lengths.
3312 * expr.c, gfortran.h, resolve.c: Updated copyright years.
3314 2006-01-03 Steven G. Kargl <kargls@comcast.net>
3317 * resolve.c (resolve_forall_iterators): Check for scalar variables;
3318 Check stride is nonzero.
3320 2006-01-02 Steven G. Kargl <kargls@comcast.net>
3323 * parse.c (next_free): Check for whitespace after the label.
3324 * match.c (gfc_match_small_literal_int): Initialize cnt variable.
