5252 was a leftover from an earlier version of the routine. Move
5253 several routines out to avoid deep nesting and indentation.
5254 (Inputs_Match): Add formal parameter Dep_Clause. Rename formal
5255 parameter Do_Checks to Post_Errors. Update the comment on usage.
5256 (Is_Matching_Input): Renamed to Input_Match. Add formal parameters

5339 the logic that generates a runtime check to determine the

5428 * s-taskin.ads: Minor comment fix.
5429 * s-tassta.adb (Abort_Dependents): Don't abort all dependents;
5430 just direct dependents. If this is actually an abort, each task
5431 will take care of aborting its dependents, so all dependents will
5432 get aborted, as before. However, when this is called the second
5433 time from Vulnerable_Complete_Master "for convenience" (i.e. to
5434 kill off tasks waiting at terminate alternatives), aborting
5435 indirect dependents is wrong, because it causes some unrelated
5436 tasks to get aborted.

5938 explicitly whether value is in range of Character, because the
5939 library is typically compiled with range checks disabled, and
5940 we cannot rely on the implicit check on the argument of 'Val.
5942 2014-01-27 Vincent Celier <celier@adacore.com>
5944 * a-ciorma.adb, a-cihama.adb (Assign): Copy the Source to the Target,

8138 * sem_ch10.adb (Expand_With_Clause): Don't
8139 recurse on the prefix if the current with-ed name refers to a

8155 2014-01-20 Yannick Moy <moy@adacore.com>
8157 * adabkend.adb, ali-util.adb, errout.adb, exp_ch7.adb,

8160 * sem_prag.adb, sem_res.adb, sem_util.adb Rename SPARK_Mode into
8162 * sem_ch13.adb: Remove blank.
8163 * exp_spark.adb, exp_spark.ads (Expand_SPARK_Call): Only replace
8164 subprograms by alias for renamings, not for inherited primitive
8166 * exp_util.adb (Expand_Subtype_From_Expr): Apply the expansion
8168 (Remove_Side_Effects): Apply the removal in
8169 GNATprove mode, for the full analysis of expressions.
8170 * expander.adb (Expand): Call the light SPARK expansion in GNATprove
8172 (Expander_Mode_Restore, Expander_Mode_Save_And_Set): Ignore
8173 save/restore actions for Expander_Active flag in GNATprove mode,

8199 * gcc-interface/decl.c (gnat_to_gnu_entity) <object>: Robustify tests
8200 for aliased objects with an unconstrained nominal subtype.
8201 * gcc-interface/trans.c (Call_to_gnu): Likewise.
8202 (gnat_to_gnu) <case N_Op_Not>: Robustify test for private type.
8203 <case N_Op_Minus>: Remove useless code.

8208 * gcc-interface/decl.c (gnat_to_gnu_entity) <case E_Record_Subtype>:
8209 Tidy up. For a subtype with discriminants and variant part, if a
8210 variant is statically selected and the fields all have a constant
8211 position, put them in order of increasing position. Likewise if
8212 no variant part but representation clause is present.
8213 * gcc-interface/utils.c (make_packable_type): Robustify.
8214 (maybe_pad_type): Use local variable and tidy up condition. If no
8215 alignment is specified, use the original one.

8218 <case CONSTRUCTOR>: Deal with padding types around the same type.
8219 Do not punt on missing fields.
8220 (unchecked_convert): Call finish_record_type to lay out the special
8221 record types made for conversions from/to problematic integer types.
8222 Bump the alignment of CONSTRUCTORs before converting them to a more

8229 improve wording of comments.
