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). Untailored_Exception_Information always uses hexadecimal addresses in the traceback, has a stable and portable output, and is now used for streaming. 2014-07-30 Eric Botcazou * exp_aggr.adb (Expand_Array_Aggregate): Add missing test on the target of the assignment to find out whether it can be directly done by the back-end. * exp_util.adb (Is_Possibly_Unaligned_Slice): Remove obscure test. 2014-07-30 Robert Dewar * inline.adb, a-coorse.adb, a-coorse.ads, a-cohase.adb, a-cohase.ads, a-tasatt.adb: Minor reformatting. 2014-07-30 Robert Dewar * exp_ch4.adb: Minor reformatting. 2014-07-30 Ed Schonberg * a-coorse.adb, a-coorse.ads (Generic_Keys): Add a Reference_Control_Type to generic package, to keep additional information for Reference_Types that manipulate keys. Add Adjust and Finalize procedures for this type.

(Insert): Detect tampering. (Reference_Preserving_Key): Build proper Reference_Control_Type, and update Busy and Lock bits to detect tampering. * a-cohase.ads: Keep with-clause private. 2014-07-30 Hristian Kirtchev * exp_ch4.adb (Expand_N_Op_Eq): Emit a warning when the operands of an equality are of an Unchecked_Union type and lack inferable discriminants. 2014-07-30 Bob Duff * g-exctra.adb, g-exctra.ads, s-exctra.adb, s-exctra.ads, Makefile.rtl, g-trasym.adb, g-trasym.ads, s-trasym.adb, s-trasym.ads: Move GNAT.Traceback.Symbolic and GNAT.Exception_Traces into the System hierarchy (System.Traceback.Symbolic and System.Exception_Traces), so we can call them from the runtimes. Leave renamings in place under GNAT. 2014-07-30 Yannick Moy * inline.adb (Check_And_Build_Body_To_Inline): Include code for inlining in GNATprove mode. 2014-07-30 Ed Schonberg * a-cohase.adb, a-cohase.ads (Generic_Keys): Add a Reference_Control_Type to generic package, to keep additional information for Reference_Types that manipulate keys.

Use an array for the Traceback parameter instead of an Address. This will enable reduction in code duplication. 2014-07-30 Pat Rogers * gnat_ugn.texi: Corrected minor textual error in description of switch -gnatwl. 2014-07-30 Bob Duff * Makefile.rtl: Sort file names. 2014-07-30 Arnaud Charlet * a-tasatt.adb: Complete previous change: kill spurious warning on e.g. sparc, and make sure we only use the fast path when the alignment is compatible. 2014-07-30 Yannick Moy * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Mark new Spec_Id as coming from source. 2014-07-30 Yannick Moy * inline.adb (Build_Body_To_Inline): Issue more precise messages for declarations that prevent inlining. (Cannot_Inline): Change usual start of message to refer to contextual analysis in GNATprove mode. * sem_res.adb (Resolve_Call): Change usual start of message to refer to contextual analysis in GNATprove mode, when inlining not possible. 2014-07-30 Robert Dewar * sem_res.adb, sem_ch6.adb: Minor code reorganization. * inline.adb: Minor reformatting. 2014-07-30 Javier Miranda * a-tags.ads: Add comments. 2014-07-30 Pat Rogers * gnat_rm.texi: Minor word error. 2014-07-30 Ed Schonberg * exp_prag.adb (Expand_Old): Insert declarationss of temporaries created to capture the value of the prefix of 'Old at the beginning of the current declarative part, to prevent data flow anomalies in the postcondition procedure that will follow. 2014-07-30 Yannick Moy * debug.adb: Retire debug flag -gnatdQ. * inline.adb (Can_Be_Inlined_In_GNATprove_Mode): Check SPARK_Mode on decl, not on body. Ignore predicate functions. * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Remove use of debug flag -gnatdQ. Correctly analyze SPARK_Mode on decl and body when generating a decl for a body on which SPARK_Mode aspect is given. * sem_prag.adb (Analyze_Pragma|SPARK_Mode): Reorder tests for attaching pragma to entity, to account for declaration not coming from source. * sem_res.adb (Resolve_Call): Issue warning and flag subprogram as not always inlined in GNATprove mode, when called in an assertion context. 2014-07-30 Vincent Celier * debug.adb: Minor comment update. 2014-07-30 Robert Dewar * s-tasuti.adb, s-tassta.adb: Minor reformatting. * sprint.adb (Sprint_Node): Handle N_Contract case. * exp_prag.adb: Minor reformatting. * freeze.adb (Freeze_Entity): Check useless postcondition for No_Return subprogram. * sem_prag.adb: Minor reformatting. 2014-07-30 Javier Miranda * a-tags.ads: Complete comments about performance. 2014-07-30 Fedor Rybin * gnat_ugn.texi: Adding description for --exit-status option to gnattest section.

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. (Make_Passive): Remove the workaround for the race condition in Make_Independent. * frontend.adb (Frontend): Revert to previous method of detecting temporary configuration pragma files, recognizing such files by ".tmp" in the name. This is more general than detecting pragmas Source_File_Name_Project, because it allows any tool to use this naming convention, no matter the content of the file. * gnat_ugn.texi: Document this naming convention. 2014-07-30 Robert Dewar * exp_ch7.adb, s-tataat.adb, s-tataat.ads, s-parame-vms-alpha.ads, inline.adb, s-parame-hpux.ads, exp_smem.adb, s-tasini.adb, s-tasini.ads, s-parame-vms-ia64.ads, s-parame.ads, s-taskin.ads, s-parame-vxworks.ads, a-tasatt.adb, a-tasatt.ads: Minor reformatting. * a-suenco.adb (Convert): Handle overlong encodings in UTF8-UTF8 conversion. 2014-07-30 Ed Schonberg * sem_ch5.adb: Improve error recovery. * inline.adb (Build_Body_To_Inline): Set Full_Analysis to false before analyzing the body, so that in GNATprove mode there is no light expansion. Whatever expansion is required by SPARK will be performed when analysing the inlined code. 2014-07-30 Bob Duff * s-tataat.adb, s-tataat.ads, a-tasatt.adb: Minor comment fixes. 2014-07-30 Ed Schonberg * sem_ch5.adb (Analyze_Loop_Statement): If loop has a label, verify that it is not hidden by an inner implicit declaration. 2014-07-30 Thomas Quinot * sem.ads (Scope_Table_Entry): New component Locked_Shared_Objects. * sem_ch8.adb (Push_Scope): Initialize Locked_Shared_Objects. * exp_smem.adb (Add_Shared_Var_Lock_Procs): Handle the case where the call returns an unconstrained type: in this case there is already a transient scope, and we should not establish a new one. * exp_ch7.adb (Insert_Actions_In_Scope_Around): New formal Clean. If True, also insert cleanup actions in the tree. (Wrap_Transient_Declaration): Call Insert_Actions_In_Scope_Around with Clean set True. 2014-07-30 Arnaud Charlet * s-taskin.ads (Direct_Index, Direct_Index_Range, Direct_Attribute_Element, Direct_Attribute_Array, Direct_Index_Vector, Direct_Attributes, Is_Defined, Indirect_Attributes): Removed.

This is in contrast to conversions in other contexts, where the operand cannot be a literal and must be resolvable independent of the context. 2014-07-30 Pierre-Marie Derodat * gcc-interface/decl.c (gnat_to_gnu_entity) : Create a mere scalar constant instead of a reference for a renaming of scalar literal. * gcc-interface/utils.c (renaming_from_generic_instantiation_p): New. * gcc-interface/gigi.h (renaming_from_generic_instantiation_p): New. 2014-07-30 Robert Dewar * s-tasuti.adb, s-tasuti.ads, einfo.ads, sem_prag.adb, s-taasde.adb, g-socthi-vms.adb, s-taprop-mingw.adb, s-interr.adb, s-interr-hwint.adb, g-decstr.adb, s-tasdeb-vms.adb, g-expect-vms.adb, makeutl.adb, s-interr-vms.adb, g-socthi.adb, exp_aggr.adb, s-tasdeb.adb, g-awk.adb, gnatls.adb, s-taspri-posix.ads, g-catiio.adb, s-interr-sigaction.adb, s-os_lib.adb, s-fileio.adb: Minor reformatting & code reorganization. 2014-07-30 Bob Duff * s-tassta.adb, sem_util.ads: Minor reformatting. 2014-07-30 Yannick Moy * inline.adb (Build_Body_To_Inline): Detect when subprogram has multiple returns, or not a single last return statement, in GNATprove mode.

This causes the activating task to wait until after Make_Independent is complete before proceeding. In addition, we initialize data structures used by independent tasks before activating those tasks, to avoid possible use of uninitialized data. * s-interr.ads, s-intman.ads, s-taspri-posix.ads, s-tasdeb.ads: Minor comment fixes. 2014-07-30 Bob Duff * a-exctra.ads, s-traent-vms.ads, s-traent.ads (Tracebacks_Array): Move the declaration of Tracebacks_Array from Ada.Exceptions.Traceback to System.Traceback_Entries (s-traent.ads and s-traent-vms.ads). Add subtypes renaming Tracebacks_Array in Ada.Exceptions.Traceback. * g-debpoo.adb: Refer to Tracebacks_Array in its new home. 2014-07-30 Arnaud Charlet * a-tasatt.adb: Remove old comments. 2014-07-30 Yannick Moy * einfo.ads (Is_Inlined): Document new use in GNATprove mode. * inline.adb (Can_Be_Inlined_In_GNATprove_Mode): Add comments to explain rationale for inlining or not in GNATprove mode.

This avoids the "not No_xxx" situation which is always ugly. 2014-07-30 Ed Schonberg * inline.adb (Expand_Inlined_Call): When generating code for an internal subprogram the expansion uses the location of the call, so that gdb can skip over it. In GNATprove mode we want to preserve slocs of original subprogram when expanding an inlined call, to obtain better warnings, even though subprogram appears not to come from source if it is the inlining of a subprogram body without a previous spec. 2014-07-30 Eric Botcazou * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): Reject array types with atomic components. 2014-07-30 Thomas Quinot * Make-generated.in: Remove now unnecessary targets after s-oscons reorg. 2014-07-30 Yannick Moy * sem_res.adb (Resolve_Call): Use ultimate alias of callee when available. 2014-07-30 Ed Schonberg * sem_ch6.adb (Analyze_Expression_Function): To check whether an expression function is a completion, use the specification of the previous declaration, not its entity, which may be internally generated in an inlined context. 2014-07-30 Doug Rupp * adaint.c (__gnat_tmp_name) [__ANDROID__]: Default to putting temp files in /cache directory unless overridden by TMPDIR. 2014-07-30 Jose Ruiz * s-tassta.adb, s-tarest.adb (Initialize, Create_Task, Create_Restricted_Task): Remove redundant check.

(Analyze_Attribute): Major cleanup of attribute 'Update. The logic is now split into two distinct routines depending on the type of the prefix. The use of <> is now illegal in attribute 'Update.

For one thing, this is anomalous (in particular, the base type might not itself be frozen yet); furthermore, proper freezing of the subtype must happen in any case. So, we just mark the subtype as requiring delayed freezing (and we'll actually freeze it when generating the init_proc of the enclosing record).
