5241 was a leftover from an earlier version of the routine. Move
5242 several routines out to avoid deep nesting and indentation.
5243 (Inputs_Match): Add formal parameter Dep_Clause. Rename formal
5244 parameter Do_Checks to Post_Errors. Update the comment on usage.

5418 * s-tassta.adb (Abort_Dependents): Don't abort all dependents;
5419 just direct dependents. If this is actually an abort, each task
5420 will take care of aborting its dependents, so all dependents will
5421 get aborted, as before. However, when this is called the second
5422 time from Vulnerable_Complete_Master "for convenience" (i.e. to
5423 kill off tasks waiting at terminate alternatives), aborting
5424 indirect dependents is wrong, because it causes some unrelated
5425 tasks to get aborted.

7171 the original one. the modification of the name must preserve
7172 the source location of the original, to prevent spurious errors
7173 when compiling with style checks if the declaration involves
7174 more than one entity.

8127 * sem_ch10.adb (Expand_With_Clause): Don't

8151 * sem_ch13.adb: Remove blank.
8152 * exp_spark.adb, exp_spark.ads (Expand_SPARK_Call): Only replace

8157 (Remove_Side_Effects): Apply the removal in
8158 GNATprove mode, for the full analysis of expressions.

8161 (Expander_Mode_Restore, Expander_Mode_Save_And_Set): Ignore
8162 save/restore actions for Expander_Active flag in GNATprove mode,
8163 similar to what is done in ASIS mode.

8188 * gcc-interface/decl.c (gnat_to_gnu_entity) <object>: Robustify tests
8189 for aliased objects with an unconstrained nominal subtype.
8190 * gcc-interface/trans.c (Call_to_gnu): Likewise.
8191 (gnat_to_gnu) <case N_Op_Not>: Robustify test for private type.
8192 <case N_Op_Minus>: Remove useless code.

8197 * gcc-interface/decl.c (gnat_to_gnu_entity) <case E_Record_Subtype>:
8198 Tidy up. For a subtype with discriminants and variant part, if a
8199 variant is statically selected and the fields all have a constant
8200 position, put them in order of increasing position. Likewise if
8201 no variant part but representation clause is present.
8202 * gcc-interface/utils.c (make_packable_type): Robustify.
8203 (maybe_pad_type): Use local variable and tidy up condition. If no
8204 alignment is specified, use the original one.
8205 (create_type_stub_decl): Minor tweak.

8207 <case CONSTRUCTOR>: Deal with padding types around the same type.
8208 Do not punt on missing fields.
8209 (unchecked_convert): Call finish_record_type to lay out the special
8210 record types made for conversions from/to problematic integer types.
8211 Bump the alignment of CONSTRUCTORs before converting them to a more

8216 * gcc-interface/decl.c (gnat_to_gnu_entity) <case E_Component>: Remove
8217 obsolete code for type_annotate_only mode, simplify code and slightly
8218 improve wording of comments.
