3144 * resolve.c (resolve_actual_arglist): Remove unneeded and buggy piece
3147 2011-01-09 Thomas Koenig <tkoenig@gcc.gnu.org>
3150 * resolve.c (is_scalar_expr_ptr): For a substring reference,

3169 * trans-expr.c (gfc_conv_procedure_call): With a non-copying

3171 any chance of aliasing due to host or use association.
3172 (arrayfunc_assign_needs_temporary): Correct logic for function
3173 results and do not use a temporary for implicitly PURE
3174 variables. Use a temporary for Cray pointees.

3180 add prototype for function gfc_implicit_pure.
3181 * expr.c (gfc_check_pointer_assign, gfc_check_vardef_context):
3182 Where decl would fail in PURE procedure, reset implicit_pure.
3183 * io.c (match_vtag, gfc_match_open, gfc_match_close,
3184 gfc_match_print, gfc_match_inquire, gfc_match_wait): The same.

3191 resolve_function, resolve_ordinary_assign) : The same.
3192 (gfc_implicit_pure): New function.
3193 * module.c (mio_symbol_attribute): Introduce AB_IMPLICIT_PURE
3194 to ab_attribute enum and use it in this function.

3199 * symbol.c (gfc_symbols_could_alias): Strip gfc_ prefix,
3200 make static and move in front of its only caller, to ...
3201 * trans-array.c (symbols_could_alias): ... here.
3202 Pass information about pointer and target status as
3203 arguments. Allocatable arrays don't alias anything
3204 unless they have the POINTER attribute.
3205 (gfc_could_be_alias): Keep track of pointer and target
3206 status when following references. Also check if typespecs
3207 of components match those of other components or symbols.

3220 2011-01-07 Janus Weil <janus@gcc.gnu.org>
3224 * gfortran.h (gfc_lval_expr_from_sym): Moved prototype.

3244 * trans-expr.c (gfc_trans_class_assign): Bugfix for r168524 (make sure
3245 'vtab' is initialized).

3263 of polymorphic allocatables according to their declared type.
3265 2011-01-04 Janus Weil <janus@gcc.gnu.org>
3268 * class.c (gfc_find_derived_vtab): Set the module field for the copying
3269 routine to make sure it receives module name mangling.
