For a field that needs strict alignment, issue the error for the position first and, for the size, issue an error if it is too large only for the atomic and aliased cases. Issue a specific error if the size is not a multiple of a byte in the volatile and the strict alignment cases. 2014-12-22 Eric Botcazou <ebotcazou@adacore.com> * gcc-interface/decl.c (check_ok_for_atomic): Rename into...

T.Common.Domain should never be null; so Assert. Remove similar code from Create_Task in s-tassta.adb. * s-mudido-affinity.adb: Remove checks for Domain = null, because it can't be null. * s-taskin.ads, s-taspri-dummy.ads, s-taspri-mingw.ads, s-taspri-posix.ads, s-taspri-posix-noaltstack.ads, s-taspri-solaris.ads, s-taspri-vxworks.ads: Mark limited types as explicitly limited for clarity. 2014-11-20 Ed Schonberg <schonberg@adacore.com> * exp_aggr.adb (Init_Hidden_Discriminants): Code clean up. 2014-11-20 Robert Dewar <dewar@adacore.com> * errout.adb (Error_Msg): Don't suppress continuation msgs for run-time files. * sem_prag.adb (Analyze_Pragma, case Elaborate): Forbid pragma Elaborate in SPARK mode. 2014-11-20 Yannick Moy <moy@adacore.com> * gnat_rm.texi: Update GNAT RM with rule about expressions in Update attribute. 2014-11-20 Thomas Quinot <quinot@adacore.com> * g-socket.adb (To_Host_Entry): Guard against case of a non-AF_INET entry. 2014-11-20 Vadim Godunko <godunko@adacore.com> * a-strunb-shared.adb (To_Unbounded_String): Use shared empty object to construct return value when source string is empty or requested length is zero. * a-stwiun-shared.adb (To_Unbounded_Wide_String): Likewise. * a-stzunb-shared.adb (To_Unbounded_Wide_Wide_String): Likewise. 2014-11-20 Yannick Moy <moy@adacore.com> * a-cfhase.adb, a-cfinve.adb, a-cforma.adb, a-cfhama.adb, a-cforse.adb, a-cofove.adb: Skip CodePeer analysis on body of all formal containers. 2014-11-20 Arnaud Charlet <charlet@adacore.com> * adaint.c: Fix typo. * exp_util.adb (Make_Subtype_From_Expr): Complete previous change, generate constant values. * sem_eval.adb (Decompose_Expr): Fix latent bug leading to a wrong evaluation to '0' of some unknown values. 2014-11-20 Robert Dewar <dewar@adacore.com> * repinfo.adb (List_Record_Info): Do not list discriminant in unchecked union. * sem_ch13.adb (Has_Good_Profile): Minor reformatting (Analyze_Stream_TSS_Definition): Minor reformatting (Analyze_Record_Representation_Clause): Do not issue warning for missing rep clause for discriminant in unchecked union. 2014-11-20 Vadim Godunko <godunko@adacore.com> * a-strunb-shared.adb, a-stwiun-shared.adb, a-stzunb-shared.adb ("&") Use already computed value of data length to call allocation subprogram. 2014-11-20 Ed Schonberg <schonberg@adacore.com> * exp_ch6.adb (Expand_Call, Inlined_Subprogram): Do not suppress debugging information for a call to a predefined unit, if the call comes from source and the unit is in the Ada hierarchy. 2014-11-20 Bob Duff <duff@adacore.com> * s-mudido.ads: Update signature of Create and Get_Last_CPU.

Also minor cleanup: use raise_expressions. * s-mudido-affinity.adb: Implementations of new operations from * s-mudido.ads, for the platforms that actually support processor affinity.

However, it was also used to implement the stream attributes for type Exception_Occurrence. The latter requires a stable and portable interface, which meant that we couldn't include a symbolic traceback. A separate set of routines was used to provide symbolic tracebacks under program control (i.e. not automatically). The goal of this ticket is to provide such automatic tracebacks, so the change here is to split the two functionalities: Exception_Information gives the maximally useful information for debugging (i.e. it now includes a symbolic traceback when a decorator is set, and it can be improved freely in the future without disturbing streaming).

This was not true, for example, in s-interr.adb, when Interrupt_Manager does "new Server_Task"; the Server_Task had Parent = Interrupt_Manager, which is wrong because the master is determined by the access type, which is at library level. * s-tasuti.adb (Make_Independent): Avoid setting Parent; it is now set correctly by Create_Task.

(Remove_Side_Effects): Apply the removal in GNATprove mode, for the full analysis of expressions. * expander.adb (Expand): Call the light SPARK expansion in GNATprove mode. (Expander_Mode_Restore, Expander_Mode_Save_And_Set): Ignore save/restore actions for Expander_Active flag in GNATprove mode, similar to what is done in ASIS mode. * frontend.adb (Frontend): Generic bodies are instantiated in GNATprove mode. * gnat1drv.adb (Adjust_Global_Switches): Set operating mode to Check_Semantics in GNATprove mode, although a light expansion is still performed. (Gnat1drv): Set Back_End_Mode to Declarations_Only in GNATprove mode, and later on special case the GNATprove mode to continue analysis anyway. * lib-writ.adb (Write_ALI): Always generate ALI files in GNATprove mode. * opt.adb, opt.ads (Full_Expander_Active): Make it equivalent to Expander_Active.

(gnat_to_gnu) <case N_Op_Not>: Robustify test for private type. <case N_Op_Minus>: Remove useless code.

For a subtype with discriminants and variant part, if a variant is statically selected and the fields all have a constant position, put them in order of increasing position. Likewise if no variant part but representation clause is present. * gcc-interface/utils.c (make_packable_type): Robustify. (maybe_pad_type): Use local variable and tidy up condition. If no alignment is specified, use the original one. (create_type_stub_decl): Minor tweak. (convert) <case VECTOR_CST>: Fix typo. <case CONSTRUCTOR>: Deal with padding types around the same type. Do not punt on missing fields. (unchecked_convert): Call finish_record_type to lay out the special record types made for conversions from/to problematic integer types. Bump the alignment of CONSTRUCTORs before converting them to a more aligned type. 2014-01-20 Eric Botcazou <ebotcazou@adacore.com> * gcc-interface/decl.c (gnat_to_gnu_entity) <case E_Component>: Remove obsolete code for type_annotate_only mode, simplify code and slightly improve wording of comments. 2014-01-12 Eric Botcazou <ebotcazou@adacore.com> PR ada/59772 * gcc-interface/cuintp.c (build_cst_from_int): Use 32-bit integer type as intermediate type.
