	* a-elchha.adb, a-except-2005.adb, a-except.adb, a-exexda.adb,
	* a-exextr.adb, a-exstat.adb, exp_intr.ads, s-tassta.adb:
	Exception_Information is used to produce useful debugging
	information for the programmer. 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.

	anomalies in the postcondition procedure that will follow.

2014-07-30  Yannick Moy  <moy@adacore.com>

	* 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  <celier@adacore.com>

	* debug.adb: Minor comment update.

2014-07-30  Robert Dewar  <dewar@adacore.com>

	* 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  <miranda@adacore.com>

	* a-tags.ads: Complete comments about performance.

2014-07-30  Fedor Rybin  <frybin@adacore.com>

	* gnat_ugn.texi: Adding description for --exit-status option to

	in gnattest section.

2014-07-30  Javier Miranda  <miranda@adacore.com>

	* Makefile.rtl, gnat_rm.texi, i-cpp.adb, i-cpp.ads, impunit.adb,

	package is no longer needed.

2014-07-30  Bob Duff  <duff@adacore.com>

	* s-taasde.adb (Timer_Queue): Don't use a
	build-in-place function call to initialize the Timer_Queue.
	* s-traent.adb, s-traent.ads, s-traent-vms.adb, s-traent-vms.ads:
	Turn off polling in these units, because otherwise we get
	elaboration circularities with Ada.Exceptions when the -gnatP
	switch is used.
	* s-tassta.adb (Create_Task): Make sure independent tasks
	are created with Parent = Environment_Task. 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.

	* 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

	specified first subtype.

2014-07-30  Ed Schonberg  <schonberg@adacore.com>

	* inline.adb (Expand_Inlined_Call): Use a renaming declaration
	to capture the value of actuals of a limited type rather than
	an object declaration, to prevent spurious errors when analyzing
	the inlined body.

2014-07-30  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch4.adb (Analyze_Type_Conversion): Treat an inlined body
	as an instance, and inhibit semantic checks on already analyzed

	is legal in an inlined body, juts as it is in an instance body.

2014-07-30  Ed Schonberg  <schonberg@adacore.com>

	* sem_res.adb (Resolve_Unchecked_Conversion): Within an inlined
	body the operand of an unchecked conversion may be a literal, in
	which case its type is the target type of the conversion. 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  <derodat@adacore.com>

2014-07-30  Bob Duff  <duff@adacore.com>

	* s-tasuti.ads, s-tasuti.adb (Make_Independent): Change this
	from a procedure to a function, so that it can more easily be
	called before the "begin" of a task.
	* s-taasde.ads (Delay_Block): Make this type immutably limited,
	so we can use a build-in-place function call to initialize

	* s-interr.adb, s-interr-hwint.adb, s-interr-sigaction.adb,
	* s-interr-vms.adb, s-taasde.adb: Each independent task now calls
	Make_Independent before reaching its "begin", to avoid race
	conditions. 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.

	* exp_attr.adb, checks.adb, sem_util.adb, sem_util.ads, sem_attr.adb:
	Change No_Scalar_Parts predicate to Scalar_Part_Present and

	which is always ugly.

2014-07-30  Ed Schonberg  <schonberg@adacore.com>

	* 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

	* sem_ch3.adb (Constrain_Corresponding_Record): For the case
	of the subtype created for a record component, do not mark
	the subtype as frozen. 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).
	Also change the name of the constrained record subtype (append a
	'C' so that it is clearly different from the unconstrained record
	type, "related_idV") to make debugging easier.
	(Process_Full_View): When creating a full subtype for a pending

	so that we get proper visibility on outer discriminants.

	parameter of a null-excluding access type, there is access check
