554 a subunit.
555 * sem_ch10.adb Remove with and use clause for Sem_Ch13.
556 (Analyze_Proper_Body): Add local variable Comp_Unit. Unum
557 is now a local variable. Code cleanup. Analysis related to
558 the aspects of a subprogram body stub is now carried out by
559 Analyze_Subprogram_Body_Helper. Do not propagate the aspects
560 and/or pragmas of a subprogram body stub to the proper body
561 as this is no longer needed. Do not analyze the aspects of a

592 variables Block_Id, Block_Nod and Iter_Loop. Mark the generated

690 used to perform pre-analysis of the expression for SPARK
691 aspects that have a non-standard syntax, such as GLobal and

693 in an aspect specification, prior to the analysis of the
694 corresponding pragma, in order to provide semantic information
695 for ASIS navigation purposes.

2412 2014-02-06 Hristian Kirtchev <kirtchev@adacore.com>
2414 * sem_util.adb (Has_Enabled_Property): Rename
2415 formal parameter Prop_Nam to Property. Update the comment on usage
2416 and all occurrences in the body. Add local variable Prop_Nam. When

2431 * exp_ch5.adb (Expand_Iterator_Loop): For a container element
2432 iterator, indicate that the element is a constant if the container
2433 type does not have a variable indexing aspect.
2434 * sem_ch8.adb (Analyze_Object_Renaming): If the entity is already
2435 marked as constant, do not reset its Ekind, to ensure that
2436 container elements in an element loop are not modified if the
2437 container (e.g. a hashed set) only has a constant indexing aspect.

2466 * sinfo.ads: Further comments on N_Expression_With_Actions node.

2470 * sem_prag.adb (Analyze_Refined_Depends_In_Decl_Part): Remove global
2471 variables Out_Items and Ref_Global. Remove local constant
2472 Body_Id along with dummy variables D1, D2, D3, D4, D5, D6, D7
2473 and D8. Remove the useless collection of global items as this
2474 was a leftover from an earlier version of the routine. Move
2475 several routines out to avoid deep nesting and indentation.
2476 (Inputs_Match): Add formal parameter Dep_Clause. Rename formal
2477 parameter Do_Checks to Post_Errors. Update the comment on usage.
2478 (Is_Matching_Input): Renamed to Input_Match. Add formal parameters
2479 Ref_Inputs and Do_Checks. Rename formal parameter Do_Checks
2480 to Post_Errors. Update the comment on usage. Account for the
2481 case where a self referential state may have a null input_list.
2482 (Is_Self_Referential): New routine.

2491 'Alignment): If the entity renames an expression, introduce

2493 use temporary.
2495 2014-02-04 Gary Dismukes <dismukes@adacore.com>
2497 * g-comlin.adb: Minor typo fix.
2499 2014-02-04 Ed Schonberg <schonberg@adacore.com>
2501 * freeze.adb (Freeze_All): Types derived from a formal

2510 * exp_ch4.adb (Expand_N_Expression_With_Actions): Eliminate
2511 cases where Actions is a null list.
2512 * sinfo.ads (N_Expression_With_Actions): Actions can be
2513 temporarily empty during semantic analysis, but must be non-empty
2514 in the final expanded tree.
2516 2014-01-31 Robert Dewar <dewar@adacore.com>
2518 * exp_ch9.adb: Minor reformatting.

2522 * g-comlin.adb (Set_Command_Line): Take the switches
2523 configuration from the Command_Line_Config.

2561 the logic that generates a runtime check to determine the
2562 controlled status of the object about to be allocated or

2565 (Find_Object): Detect

2567 the object appears as a complex expression.

2620 * sem_prag.adb (Analyze_Pragma/Pragma_SPARK_Mode):
2621 Issue an error when the pragma is applied to a generic unit,
2622 a generic declaration, or inside a generic.
2624 2014-01-31 Yannick Moy <moy@adacore.com>
2626 * sem_ch8.adb (Analyze_Subprogram_Renaming): Set SPARK_Mode on renaming
2627 entity.

2650 * s-taskin.ads: Minor comment fix.
2651 * s-tassta.adb (Abort_Dependents): Don't abort all dependents;
2652 just direct dependents. If this is actually an abort, each task
2653 will take care of aborting its dependents, so all dependents will
2654 get aborted, as before. However, when this is called the second
2655 time from Vulnerable_Complete_Master "for convenience" (i.e. to
2656 kill off tasks waiting at terminate alternatives), aborting
2657 indirect dependents is wrong, because it causes some unrelated
2658 tasks to get aborted.

2662 * sem_ch4.adb: Minor reformatting.

3159 * a-suenst.adb: strings.utf_encoding.strings (Decode): Check
3160 explicitly whether value is in range of Character, because the
3161 library is typically compiled with range checks disabled, and

3288 * exp_ch4.adb (Expand_Concatenate): If the target of the
3289 concatenation is a library-level entity, always use the off-line
3290 version of concatenation, regardless of optimization level. This

3717 2014-01-24 Robert Dewar <dewar@adacore.com>

4237 in Actions list of an N_Expression_With_Actions.
4238 * sem_elab.adb (Insert_Elab_Check): Remove complex
4239 specialized circuitry for the case where the context is already

4399 * exp_ch3.adb (Expand_N_Object_Declaration): When a class-wide
4400 object is declared, it is rewritten as a renaming of an dynamic
4401 expression that wraps the initial value. The renaming declaration

4403 entity already declared, and then the name is modified to reflect
4404 the original one. the modification of the name must preserve
4405 the source location of the original, to prevent spurious errors
4406 when compiling with style checks if the declaration involves
4407 more than one entity.

5383 GNATprove_Mode.
5384 * sem_ch13.adb: Remove blank.
5385 * exp_spark.adb, exp_spark.ads (Expand_SPARK_Call): Only replace
5386 subprograms by alias for renamings, not for inherited primitive
5387 operations.
5388 * exp_util.adb (Expand_Subtype_From_Expr): Apply the expansion
5389 in GNATprove mode.
5390 (Remove_Side_Effects): Apply the removal in
5391 GNATprove mode, for the full analysis of expressions.
5392 * expander.adb (Expand): Call the light SPARK expansion in GNATprove
5393 mode.
5394 (Expander_Mode_Restore, Expander_Mode_Save_And_Set): Ignore
5395 save/restore actions for Expander_Active flag in GNATprove mode,
5396 similar to what is done in ASIS mode.

5398 GNATprove mode.
5399 * gnat1drv.adb (Adjust_Global_Switches): Set operating
5400 mode to Check_Semantics in GNATprove mode, although a light
5401 expansion is still performed.

5417 Make sure side effects are removed in GNATprove mode.
5419 2014-01-20 Eric Botcazou <ebotcazou@adacore.com>
5421 * gcc-interface/decl.c (gnat_to_gnu_entity) <object>: Robustify tests
5422 for aliased objects with an unconstrained nominal subtype.
5423 * gcc-interface/trans.c (Call_to_gnu): Likewise.
5424 (gnat_to_gnu) <case N_Op_Not>: Robustify test for private type.
5425 <case N_Op_Minus>: Remove useless code.
5426 (Exception_Handler_to_gnu_zcx): Minor tweaks.
5428 2014-01-20 Eric Botcazou <ebotcazou@adacore.com>
5430 * gcc-interface/decl.c (gnat_to_gnu_entity) <case E_Record_Subtype>:
5431 Tidy up. For a subtype with discriminants and variant part, if a
5432 variant is statically selected and the fields all have a constant
5433 position, put them in order of increasing position. Likewise if
5434 no variant part but representation clause is present.
5435 * gcc-interface/utils.c (make_packable_type): Robustify.
5436 (maybe_pad_type): Use local variable and tidy up condition. If no
5437 alignment is specified, use the original one.
5438 (create_type_stub_decl): Minor tweak.
5439 (convert) <case VECTOR_CST>: Fix typo.
5440 <case CONSTRUCTOR>: Deal with padding types around the same type.
5441 Do not punt on missing fields.
5442 (unchecked_convert): Call finish_record_type to lay out the special
5443 record types made for conversions from/to problematic integer types.
5444 Bump the alignment of CONSTRUCTORs before converting them to a more
5445 aligned type.
5447 2014-01-20 Eric Botcazou <ebotcazou@adacore.com>
5449 * gcc-interface/decl.c (gnat_to_gnu_entity) <case E_Component>: Remove
5450 obsolete code for type_annotate_only mode, simplify code and slightly
5451 improve wording of comments.

5456 * gcc-interface/cuintp.c (build_cst_from_int): Use 32-bit integer type
5457 as intermediate type.
5458 (UI_To_gnu): Likewise.

5462 * gnatvsn.ads (Current_Year): Bump to 2014.
