2143 2011-01-09 Thomas Koenig <tkoenig@gcc.gnu.org>
2146 * resolve.c (is_scalar_expr_ptr): For a substring reference,
2147 use gfc_dep_compare_expr to compare start and end expession.
2148 Add FIXME for using gfc_deb_compare_expr elsewhere.
2150 2011-01-09 Janus Weil <janus@gcc.gnu.org>
2153 * class.c (get_unique_type_string): Make type name start with upper
2156 2011-01-08 Thomas Koenig <tkoenig@gcc.gnu.org>
2159 * invoke.texi: Mention -ffree-line-length-none and
2160 -ffixed-line-length-none for preprocessing.
2162 2011-01-08 Paul Thomas <pault@gcc.gnu.org>
2165 * trans-expr.c (gfc_conv_procedure_call): With a non-copying
2166 procedure argument (eg TRANSPOSE) use a temporary if there is
2167 any chance of aliasing due to host or use association.
2168 (arrayfunc_assign_needs_temporary): Correct logic for function
2169 results and do not use a temporary for implicitly PURE
2170 variables. Use a temporary for Cray pointees.
2171 * symbol.c (gfc_add_save): Explicit SAVE not compatible with
2172 implicit pureness of containing procedure.
2173 * decl.c (match_old_style_init, gfc_match_data): Where decl
2174 would fail in PURE procedure, set implicit_pure to zero.
2175 * gfortran.h : Add implicit_pure to structure symbol_attr and
2176 add prototype for function gfc_implicit_pure.
2177 * expr.c (gfc_check_pointer_assign, gfc_check_vardef_context):
2178 Where decl would fail in PURE procedure, reset implicit_pure.
2179 * io.c (match_vtag, gfc_match_open, gfc_match_close,
2180 gfc_match_print, gfc_match_inquire, gfc_match_wait): The same.
2181 * match.c (gfc_match_critical, gfc_match_stopcode,
2182 sync_statement, gfc_match_allocate, gfc_match_deallocate): The
2184 * parse.c (decode_omp_directive): The same.
2185 (parse_contained): If not PURE, set implicit pure attribute.
2186 * resolve.c (resolve_formal_arglist, resolve_structure_cons,
2187 resolve_function, resolve_ordinary_assign) : The same.
2188 (gfc_implicit_pure): New function.
2189 * module.c (mio_symbol_attribute): Introduce AB_IMPLICIT_PURE
2190 to ab_attribute enum and use it in this function.
2192 2011-01-08 Thomas Koenig <tkoenig@gcc.gnu.org>
2195 * symbol.c (gfc_symbols_could_alias): Strip gfc_ prefix,
2196 make static and move in front of its only caller, to ...
2197 * trans-array.c (symbols_could_alias): ... here.
2198 Pass information about pointer and target status as
2199 arguments. Allocatable arrays don't alias anything
2200 unless they have the POINTER attribute.
2201 (gfc_could_be_alias): Keep track of pointer and target
2202 status when following references. Also check if typespecs
2203 of components match those of other components or symbols.
2205 2011-01-07 Tobias Burnus <burnus@net-b.de>
2208 * class.c (gfc_build_class_symbol): Mark __vtab as attr.vtab.
2209 * intrinsic.c (add_functions): Use simplify functions for
2210 EXTENDS_TYPE_OF and SAME_TYPE_AS.
2211 * intrinsic.h (gfc_simplify_extends_type_of,
2212 gfc_simplify_same_type_as): New prototypes.
2213 * simplify.c (is_last_ref_vtab, gfc_simplify_extends_type_of,
2214 gfc_simplify_same_type_as): New functions.
2216 2011-01-07 Janus Weil <janus@gcc.gnu.org>
2220 * gfortran.h (gfc_lval_expr_from_sym): Moved prototype.
2221 * class.c (gfc_class_null_initializer): Initialize _vptr to declared
2223 * expr.c (gfc_lval_expr_from_sym): Moved here from symbol.c.
2224 * resolve.c (resolve_deallocate_expr): _data component will be added
2225 at translation stage.
2226 * symbol.c (gfc_lval_expr_from_sym): Moved to expr.c.
2227 * trans-stmt.c (gfc_trans_deallocate): Reset _vptr to declared type.

2233 * parse.c (parse_interface): Remove check for procedure types.
2234 * interface.c (check_interface0): Verify that procedures are
2235 either all SUBROUTINEs or all FUNCTIONs.
2237 2011-01-05 Janus Weil <janus@gcc.gnu.org>
2240 * trans-expr.c (gfc_trans_class_assign): Bugfix for r168524 (make sure
2241 'vtab' is initialized).
2243 2011-01-05 Janus Weil <janus@gcc.gnu.org>
2246 * trans-expr.c (gfc_trans_class_assign): For a polymorphic NULL pointer
2247 assignment, set the _vptr component to the declared type.

2252 * resolve.c (resolve_allocate_deallocate): Follow references to
2253 check for duplicate occurence of allocation/deallocation objects.
2255 2011-01-05 Janus Weil <janus@gcc.gnu.org>
2258 * trans-decl.c (gfc_trans_deferred_vars): Initialize the _vpr component
2259 of polymorphic allocatables according to their declared type.
2261 2011-01-04 Janus Weil <janus@gcc.gnu.org>
2264 * class.c (gfc_find_derived_vtab): Set the module field for the copying
2265 routine to make sure it receives module name mangling.
2267 2011-01-03 Jakub Jelinek <jakub@redhat.com>

2272 2011-01-03 Janus Weil <janus@gcc.gnu.org>
