* sem_ch8.adb (Analyze_Use_Type): Code cleanup.
(Applicable_Use): Emit a warning when a package tries to use itself.
(Use_One_Type): Add variable Is_Known_Used. Emit a warning when a type
is already in use or the package where it is declared is in use or is
declared in the current package.
(Spec_Reloaded_For_Body): New subsidiary routine for Use_One_Type.
* a-tasatt.adb, s-osprim-vxworks.adb, g-socthi-mingw.adb,
s-intman-vms.adb, g-socket.adb, g-thread.adb, s-tarest.adb,
s-tassta.adb, s-tporft.adb: Remove redundant 'use type' clause.
2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
* a-calend-vms.adb, a-calend.adb:
Add a section on leap seconds control along with two entities used to
enable and disable leap seconds support. The array Leap_Second_Times is
now constant and contains hard time values pre-generated. Remove
all elaboration code used to populate the table of leap seconds.
* bindgen.adb:
Add entity Leap_Seconds_Support to the list of global run-time variables
along with a comment on its usage and values.
(Gen_Adainit_Ada): Add code to generate the declaration and import of
Integer variable Leap_Seconds_Support. Set its value to zero (disabled)
or one (enabled) depending on the presence of binder switch "-y".
(Gen_Adainit_C): Add code to generate the declaration of external int
__gl_leap_seconds_support. Set is value to zero (disabled) or one
(enabled) depending on the presence of binder switch "-y".
* init.c: Add __gl_leap_seconds_support to the list of global values
computed by the binder.

s-taprop-hpux-dce.adb, s-taprop-linux.adb, s-taprop-dummy.adb,
s-taprop-solaris.adb, s-taprop-vms.adb, s-taprop-mingw.adb,
s-taprop-posix.adb (Stop_Task): New function, dummy implementation.
* s-taprop.ads, s-taprop-vxworks.adb (Stop_Task): New function.
* s-tasdeb.adb (Stop_All_Tasks): New function, implementing a run-time
function which can be called by the debugger to interrupt the tasks of
an Ada application asynchronously, as needed on VxWorks.
(Stop_All_Tasks_Handler): Renamed from Stop_All_Tasks.
* s-tasdeb.ads (Stop_All_Tasks_Handler): New function declaration,
renamed from Stop_All_Tasks. Update comments.
(Stop_All_tasks): New function declaration.
2007-09-26 Olivier Hainque <hainque@adacore.com>
* adaint.c (if defined (__Lynx__)): Wrap #def/#undef VMOS_DEV around
#include <utime.h> and #define GCC_RESOURCE_H before
#include <sys/wait.h>.
Add more protections in __gnat_translate_vms.
* expect.c (if defined (__Lynx__)): #define GCC_RESOURCE_H before
#include <sys/wait.h>.

* gnatvsn.ads (PCS_Version_Number, ASIS_Version_Number): Removed.
* exp_dist.ads (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
where it belongs.
* opt.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
* rtsfind.adb (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
where it belongs.

* a-tags.adb:
(Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
indirection added to the HT_Link component of the TSD. This is required
to statically allocate the TSD.
* a-tags.ads:
Minor reordering of the declarations in the private part. Required to
add a level of indirection to the contents of the TSD component HT_Link.
This is required to statically allocate the TSD.
* decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
Is_Statically_Allocated set from constant objects.
Do not make exported constants created by the compiler volatile.
(gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
as read-only.
* trans.c (Identifier_to_gnu): For constants, unshare initializers
before returning them.
* exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
public part of the package.
(Make_DT): Move HT_Link component out of the TSD record. For this
purpose Make_DT now declares a separate object that stores the
HT_Link value, and initializes the TSD component with the address
of this new object. The addition of this level of indirection is
required to statically allocate the TSD because the TSD cannot
have variable components.
(Expand_Interface_Conversion): Improve the expanded code.
(Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
* sem_disp.adb (Check_Dispatching_Operation): In case of a body
declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
if we are building static dispatch tables then we must not generate
extra code to register the primitive because the dispatch table will
be built at the end of the library package; otherwise we notify that
we cannot build the static dispatch table.
2007-09-26 Robert Dewar <dewar@adacore.com>
* checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address
overlays.
* sem_ch13.ads, sem_ch13.adb: Improve warnings for address overlays
(Analyze_Record_Representation_Clause): Suppress junk warning for
missing component clause.
(Analyze_Attribute_Definition_Clause, case Address): Apply the special
tests for controlled type overlay to composites with controlled
components.
(Analyze_Record_Representation_Clause): Add reference for component name

Gary Dismukes <dismukes@adacore.com>
* einfo.adb (Is_Thunk): New attribute applicable to subprograms. True
for thunks associated with interface types.
* einfo.ads: Improve documentatation of Is_Internal
(Is_Thunk): New attribute applicable to subprograms. True for thunks
associated with interface types.
Extensive comment fixes regarding flags that appear in all entities. The
documentation is now consistent for all such flags (there were a number
of errors in the documentation in this regard).
* exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
* exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
of these procedures are passed a function call that already has
build-in-place actuals (testing new flag
Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
the case where processing continues.
(Expand_Call): If the call is generated from a thunk body then we
propagate the extra actuals associated with the accessibility
level of the access type actuals.
* sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
of each extra formal of a protected operation to reference the
corresponding extra formal of the subprogram denoted by the
operation's Protected_Body_Subprogram.
* sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
N_Function_Call nodes.
2007-09-26 Robert Dewar <dewar@adacore.com>
* exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
* debug.adb: Add d.s flag.
2007-09-26 Gary Dismukes <dismukes@adacore.com>
* exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
debug variable so that it won't be initialized when pragma
Initialize_Scalars is in effect.
2007-09-26 Gary Dismukes <dismukes@adacore.com>
* freeze.adb (Freeze_Entity): Remove check for preelaborable
initialization of a full view. This is moved to
Analyze_Package_Specification.
* sem_ch7.adb (Analyze_Package_Specification): Add check for
preelaborable initialization of a full view in entity loop.
(Uninstall_Declarations): If entity is a use-visible compilation unit,
its child units are use-visible only if they are visible child units.
* sem_util.adb (Is_Preelaborable_Expression): New function to determine
whether an expression can be used within a type declaration that
requires preelaborable init.
(Check_Components): Replace inline code that does partial checking for
preelaborable default expressions with call to
Is_Preelaborable_Expression.
(Has_Preelaborable_Initialization): In the case of a generic actual
subtype, (that is, Is_Generic_Actual is True), return the result of
applying Has_Preelaborable_Initialization to the generic actual's base
type.
2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
* g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
call to Jan_1_Day _Of_Week to optimize its performance.
(Is_Leap): Move the routine to the scope of Week_In_Year.
(Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
weekday on which January 1 falls of Year - 1 and Year + 1. This function
avoids calling Time_Of and Split, thus making it more efficent.
(Week_In_Year): Reimplemented in oder to follow ISO 8601.
* g-calend.ads (Week_In_Year): Change comment to reflect new
implementation.
2007-09-26 Emmanuel Briot <briot@adacore.com>
* g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
Command_Line): New types
(Define_Alias, Define_Prefix, Free): New subprograms. These provide
support for defining how switches can be grouped on a command line (as
is the case for -gnatw... for GNAT), and how simple switches can be
used as aliases for more complex switches (-gnatwa is same as
-gnatwbcef...)
(Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
(Start, Current_*): New subprograms
Added support for parsing an array of strings in addition to the real
command line.
(Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
be moved from the body to the private part of the spec.
(*): All subprograms now have an extra parameter with default value to
specify which parser should be used. For backward compatibility, it
defaults to parsing the command line of the application. They were also
modified to properly handle cases where each of the argument does not
start at index 1 (which is always true for Ada.Command_Line, but not
when processing any Argument_List).
(Free): New subprogram
(Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
Argument): New subprograms
(Switch_Parameter_Type): New enum, which clarifies the code. The extra
special characters like ':', '=',... are now handled in a single place,
which makes the code more extensible eventually.
(Getopt, Full_Switch): When the switch was returned as part of the
special character '*', make sure it is prepended by the switch character
('-' in general), so that the application knows whether "foo" or "-foo"
was specified on the command line.
2007-09-26 Florian Villoing <villoing@adacore.com>
* g-dirope.adb (Remove_Dir): In case we are removing directories
recursively, make sure that if an exception is raised during the
processing, the current working directory is reset to its initial
value before propagating the exception.
2007-09-26 Vincent Celier <celier@adacore.com>
* gnatbind.adb: If there are several ALI files specified and there is
a main program to bind, the first ALI is expected to contain the main
subprogram and the names of the binder generated files will be derived
from the first ALI file name.
(Gnatbind): Fix insertion character in invocation of Error_Msg
2007-09-26 Vincent Celier <celier@adacore.com>
* gnatcmd.adb (Check_Files): Do not include sources that have been
removed by attributes Exclude_Source_Files or Locally_Removed_Files.

packages Compiler and Binder.
* prj-nmsc.adb: Major rewrite of the processing of configuration
attributes for gprbuild. No impact on GNAT tools.
* prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer
process configuration attributes: this is done in Prj.Nmsc.Check.
(Recursive_Process): Make a full copy of packages inherited from project
being extended, instead of a shallow copy.
(Process_Project_Tree_Phase_1): New procedure
(Process_Project_Tree_Phase_1): New procedure
(Process): Implementation now uses the two new procedures
* prj-util.adb (Executable_Of): Get the suffix and the default suffix
from the project config, not the tree config that no longer exists.

ancestor of the derived type, the operations are inherited from the
primary dispatch table of the parent.
(OK_For_Limited_Init_In_05): Remove old comment. Reject in-place calls
when the context is an explicit type conversion.
2007-09-26 Ed Schonberg <schonberg@adacore.com>
* sem_ch4.adb (Analyze_Qualified_Expression): Apply name resolution
