(write_roots): Call gt_clear_cache on global variables with the cache
gty attribute.

* sem_prag.adb (Analyze_Pragma, case Elaborate): Forbid pragma
Elaborate in SPARK mode.
2014-11-20 Bob Duff <duff@adacore.com>
* s-taskin.adb, s-tassta.adb (Initialize_ATCB): If Domain
is null, then initialize T.Common.Domain to that of the
activating task (not the parent task!), as required by RM-D.16.1.
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.
From-SVN: r217863
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.
From-SVN: r217861
* a-strunb-shared.adb, a-stwiun-shared.adb, a-stzunb-shared.adb
("&") Use already computed value of data length to call allocation
subprogram.
From-SVN: r217860
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. Add
CPU_Set, another Create, and Get_CPU_Set.
* s-mudido.adb: Corresponding changes to the spec. New
operations just raise an exception. 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. The new Create (which takes a set) now does all the
work; the old Create (which takes a range) now just calls the
new one. Change error messages to reflect the fact that it's an
arbitrary set, not just a range.
From-SVN: r217859
2014-11-20 Robert Dewar <dewar@adacore.com>

* s-taskin.ads: Minor comment improvements.
2014-11-20 Bob Duff <duff@adacore.com>
* exp_ch9.adb: Minor comment fixes.
* s-taskin.adb (Initialize): Small simplification: pass System_Domain
to Initialize_ATCB instead of passing null and then setting the Domain
to System_Domain. This requires moving the creation of System_Domain
earlier.
* s-taprop-linux.adb (Set_Task_Affinity): Only call CPU_SET for
processors that have a True in the Domain. This is necessary if the
Domain is not all-True values.
2014-11-20 Ed Schonberg <schonberg@adacore.com>
* sem_ch13.adb (Has_Good_Profile): a) An stream attribute
for the class-wide type of an interface type is not a primitive
operation and is not subject to the restrictions of 13.13. (38/3).
b) A stream operation for an interface type must be a null
procedure, and it cannot be a function.
From-SVN: r217857
2014-11-20 Bob Duff <duff@adacore.com>
* exp_attr.adb (Attribute_Max_Size_In_Storage_Elements):
Eliminate 'Class references from the tree, because gigi crashes on
'Class. Also, don't check Nkind (Attr) -- it is known to be
N_Attribute_Reference. Assert that instead.
From-SVN: r217856

extension aggregate can itself be an extension aggregate, as
well as a call that is rewritten as a reference.
2014-11-20 Eric Botcazou <ebotcazou@adacore.com>
* inline.adb (Add_Inlined_Subprogram): Insert all programs
generated as a body or whose declaration was provided along with
the body.
2014-11-20 Javier Miranda <miranda@adacore.com>
* sem.adb (Semantics): Disable expansion if we are compiling a
separate unit under configurable runtime. By default separate
units are compiled with expansion disabled but under configurable
runtime we enable the expansion to get error messages about
missing entities.
From-SVN: r217855
2014-11-20 Ed Schonberg <schonberg@adacore.com>
* sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not apply
inlining expansion if function build in place, i.e. has a limited

(Collect_Dependency_Clause): New routine.

performs normalization of outputs.
(Normalize_Clauses): Normalize both inputs and outputs.
(Normalize_Output): Relocated to Normalize_Clauses.
* sem_prag.ads (Collect_Subprogram_Inputs_Outputs): Add new
formal parameters Synthesize and Depends_Seen and update the
comment on usage.
2014-11-20 Ed Schonberg <schonberg@adacore.com>

in Build_Predicate_Functions, to handle properly quantified
expressions in dynamic predicates.

have Right.
From-SVN: r217838
2014-11-20 Pascal Obry <obry@adacore.com>
* initialize.c (ProcListCS): New extern variable (critical section).
(ProcListEvt): New extern variable (handle).
(__gnat_initialize)[Win32]: Initialize the ProcListCS critical
section object and the ProcListEvt event.
* final.c (__gnat_finalize)[Win32]: Properly finalize the
ProcListCS critical section and the ProcListEvt event.
* adaint.c (ProcListEvt): New Win32 event handle.
(EnterCS): New routine to enter the critical section when dealing with
child processes chain list.
(LeaveCS): As above to exit from the critical section.
(SignalListChanged): Routine to signal that the chain process list has
been updated.
(add_handle): Use EnterCS/LeaveCS, also call SignalListChanged when the
handle has been added.
(__gnat_win32_remove_handle): Use EnterCS/LeaveCS,
also call SignalListChanged if the handle has been found and removed.
(remove_handle): Routine removed, implementation merged with the above.
(win32_wait): Use EnterCS/LeaveCS for the critical section. Properly
copy the PID list locally to ensure that even if the list is updated
the local copy remains valid. Add into the hl (handle list) the
ProcListEvt handle. This handle is used to signal that a change has
been made into the process chain list. This is to ensure that a waiting
call can be resumed to take into account new processes. We also make
sure that if the handle was not found into the list we start over
the wait call. Indeed another concurrent call to win32_wait()
could already have handled this process.

reference the secondary dispatch table.
(Check_Anonymous_Return): Skip internally built functions which handle
the case of null access when locating the master of a task.
* sem_res.adb (Valid_Conversion): Return true for internally
generated conversions of access to interface types added to force
the displacement of the pointer to reference the corresponding
dispatch table.

the ghostness of the matching spec, the same way convention
is inherited.

2014-11-20 Eric Botcazou <ebotcazou@adacore.com>
* sem_ch3.adb (Analyze_Object_Declaration): Swap a couple of
tests in a condition so Following_Address_Clause is invoked
only if need be.
