restrict bitfield creation to !ADDRESSABLE any more, as some BLKmode
fields claimed addressable still have to be bitfields. Use
value_factor_p instead of a raw binop construction to check for the
position's alignment.

* exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
with an implicit dereference as its prefix, use
Insert_Explicit_Dereference instead of merely rewriting the prefix into
an explicit dereference. This ensures that a reference to the original
prefix is generated, if appropriate.
* sem_util.adb (Insert_Explicit_Dereference): When an implicit
dereference is rewritten to an explicit one, generate a reference to
the entity denoted by its prefix using the original prefix node, so
the dereference can be properly recorded as a read of the denoted
access value, if appropriate.
* sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
emitting 'assigned but never read' warning on a variable on the basis
that it has an access type.
(Check_References): Emit unreferenced warning when the scope is a
subprogram body.

an external name, to be handled by the back end.
* sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
subprogram which is Imported with convention Intrinsic if an
External_Name argument is specified.
(Process_Import_Or_Interface): Properly diagnose link name argument.

with Sem_Ch6.Cannot_Inline.
(Process_Inline): Provide separate warning for inapplicable inline
pragma.

E.4(19) check.
* rtsfind.ads: New entity System.PolyORB_Interface.Make_Ref
(RE_Same_Partition): New entity, from s-parint.
* s-parint.ads, s-parint.adb (Same_Partition): New subprogram.

* nlists.adb (Prepend_Debug): Remove parameters and nest within
Prepend.
(Remove_Next_Debug): Same fix
* nlists.ads: Correct bad comments for Prev and Prev_Non_Pragma (we do
maintain back pointers now, though we did not used to, and comments
were out of date).
(Prepend): Remove pragma Inline.
(Remove_Next): Same cleanup
2004-12-07 Thomas Quinot <quinot@adacore.com>
* sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
used to record an implicit dereference as a read operation on its
prefix when operating under -gnatc. Necessary to avoid spurious
'variable assigned but never read' warnings in that mode.
(Process_Indexed_Component, Analyze_Selected_Component): When the prefix
is a non-overloaded implicit dereference, call the above subprogram to
ensure proper recording of references.
2004-12-07 Gary Dismukes <dismukes@adacore.com>

2004-12-07 Vincent Celier <celier@adacore.com>
* vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
-gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
and -eit to -ept. Added qualifier
/ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
2004-11-27 Andreas Schwab <schwab@suse.de>
* Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
2004-11-25 Arnaud Charlet <charlet@adacore.com>
* g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
internal implementation unit GNAT.Sockets.Thin,
as their usage for sockets is non-portable (using the read and write
functions from the system runtime library is fine on UNIX but won't
work under Windows).
* mingw32.h: Update copyright notice.
2004-11-25 Arnaud Charlet <charlet@adacore.com>
* ada-tree.h: Minor reformatting of previous change to avoid lines
longer than 79 characters.

* a-exexpr.adb (Others_Value, All_Others_Value): New variables, the
address of which may be used to represent "others" and "all others"
choices in exception tables, instead of the current harcoded
(void *)0 and (void *)1.
(Setup_Exception): Do nothing in the GNAT SJLJ case.
* gigi.h (others_decl, all_others_decl): New decls representing the
new Others_Value and All_Others_Value objects.

corresponding objects exported by a-exexpr, instead of hardcoded dummy
addresses.
* trans.c (Exception_Handler_to_gnu_zcx): Use the address of

to represent "others" and "all others" choices, which is cleaner and
more flexible with respect to the possible eh pointer encoding policies.

(process_attributes): Account for the naming change of the "args"
attribute list entry component.
* decl.c (build_attr_list): Rename into prepend_attributes to allow
cumulating attributes for different entities into a single list.
(gnat_to_gnu_entity): Use prepend_attributes to build the list of
attributes for the current entity and propagate first subtype
attributes to other subtypes.
<E_Procedure>: Attribute arguments are attr->args and not
attr->arg any more.
(build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
argument provided, as this is what GCC expects. Use NULL_TREE instead
of 0 for trees.
2004-11-18 Robert Dewar <dewar@adacore.com>
* a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:

string distribution identifiers assigned to a given subprogram.
(Get_Subprogram_Id): Reimplement in terms of Get_Subprogram_Ids.
(Add_RAS_Dereference_TSS): Add comments.

(First_RCI_Subprogram_Id): Document this constant.
(Add_RAS_Access_TSS): Correct the setting of the Etype of the
RAS_Access TSS.
(Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
replaced with calls to Get_Library_Unit_Name_String. Previously there
were several instances of the same code in different locations in the
compiler; this checkin completes the replacement of all of these
instances with calls to a common subprogram.
Minor reformatting.

* exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
(Expand_Pragma_Psect_Object): New procedure
These procedures contain the revised and cleaned up processing for
these two pragmas. This processing was formerly in Sem_Prag, but
is more appropriately moved here. The cleanup involves making sure
that the pragmas are properly attached to the tree, and that no
nodes are improperly shared.
* sem_prag.adb: Move expansion of Common_Object and Psect_Object
pragmas to Exp_Prag, which is more appropriate.
Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
check for duplicates Remove use of Is_Psected flag, no longer needed.
Use new Make_String_Literal function with string.

check (-gnatyx) instead of being included as a redundant construct
warning.
* sem_ch6.adb: Change name Style_Check_Subprogram_Order to
Style_Check_Order_Subprograms.
* style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,

Robert Dewar <dewar@adacore.com>
* exp_ch4.adb (Expand_N_Selected_Component): If the component is the
discriminant of a constrained subtype, analyze the copy of the
corresponding constraint, because in some cases it may be only
partially analyzed.
Removes long-lived ??? comments.
* exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
handled controlled or secondary-stack expressions within the
iteration_scheme of a loop.
* sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
bounds that may contain functions calls, to prevent memory leaks when
the bound contains a call to a function that uses the secondary stack.
(Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
generate temporaries for loop bounds that might contain function calls
that require secondary stack and/or finalization actions.
* sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
selected component and the selector is overloadable (not just a
function) treat as function call, Analyze_Call will disambiguate if
necessary.
(Analyze_Selected_Component): Do not generate an actual subtype for the
selected component if expansion is disabled. The actual subtype is only
needed for constraint checks.
(Analyze_Allocator): If restriction No_Streams is set, then do
not permit objects to be declared of a stream type, or of a
composite type containing a stream.
* restrict.ads: Remove the a-stream entry from Unit_Array, since
No_Streams no longer prohibits with'ing this package.
* sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
discriminants, but the parent base has unknown discriminants, there is
no discriminant constraint to inherit. Such a discrepancy can arise
when the actual for a formal type with unknown discriminants is a

* g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
(Check_Selector): Use C_Recv instead of C_Read.
Selectors are the GNAT.Sockets abstraction to perform a select()
call on a set of descriptors. To allow abortion of an ongoing
select operation, some data is written to a dedicated socket that
is always monitored.
Under Windows, the write and read library functions cannot operate
on sockets, so we need to use send and recv instead, which is portable
across all supported platforms.

inherited components of derived types, to provide complete information.
* exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that

It is necessary to mark this entity as a variable, in addition to
flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
modified to avoid checking the Aliased flag on entities that are not
objects. (Checking that flag for non-objects is erroneous and could
lead to a compiler crash).

It is therefore necessary to take a copy of the expression when building
the corresponding assignment statement in the init proc.
As a side effect, in the case of a derived record type, we now see the
original expression, without any rewriting that could have occurred

explain that when a time of day corresponding to the non existing hour
on the day switching to DST is specified, Split may return a different
value for Seconds.

(Normalize_Pathname): Only resolve VMS logical names when on VMS.
* mlib-prj.adb (Build_Library): New flag Gtrasymobj_Needed, initialize
to False.
If Gtrasymobj_Needed is True, add the full path of g-trasym.obj to

2004-06-07 Thomas Quinot <quinot@act-europe.fr>
* bindgen.adb (Set_Unit_Number): Units is an instance of Table, and so
the index of the last element is Units.Last, not Units.Table'Last
(which is usually not a valid index within the actually allocated
storage for the table).
* exp_ch4.adb (Insert_Dereference_Action): Change predicate that
determines whether to generate a call to a checked storage pool
Dereference action.
Generate such a call only for a dereference that either comes from
source, or is the result of rewriting a dereference that comes from
source.
2004-06-07 Romain Berrendonner <berrendo@act-europe.fr>

* lib-xref.adb (Generate_Reference): Add nested function Is_On_LHS. It
includes case of a variable referenced on the left hand side of an
assignment, therefore remove redundant code. Variables and prefixes of
indexed or selected components are now marked as referenced on left
hand side. Warnings are now properly emitted when variables or prefixes
are assigned but not read.
* sem_warn.adb (Output_Unreferenced_Messages): Add additional checks to
left hand side referenced variables. Private access types do not
produce the warning "variable ... is assigned but never read".
Add also additional checks to left hand side referenced variables.
Aliased, renamed objects and access types do not produce the warning
"variable ... is assigned but never read" since other entities may read
the memory location.
2004-06-07 Jerome Guitton <guitton@act-europe.fr>
* Makefile.in: In the powerpc/vxworks-specific section, restore
EXTRA_GNATRTL_NONTASKING_OBJS and EXTRA_GNATRTL_TASKING_OBJS (removed

routine to insert conversions when needed, and complete resolution of
node.

interpretations for rewritten right operand.
(Set_Mixed_Mode_Operand): Handle properly a universal real operand when
the other operand is overloaded and the context is a type conversion.

Expand_N_Unchecked_Type_Conversion): Special handling when target type
is Address, to avoid typing anomalies when Address is a visible integer
type.
* exp_ch6.adb (Expand_N_Subprogram_Body): Use Is_Descendent_Of_Address
to determine whether a subprogram should not be marked Pure, even when
declared in a pure package.
2004-05-27 Jose Ruiz <ruiz@act-europe.fr>
* gnat_ugn.texi: Replace pragma Ravenscar by pragma Profile.
* gnat_rm.texi: Replace Max_Entry_Queue_Depth by Max_Entry_Queue_Length
Document No_Dynamic_Attachment, that supersedes No_Dynamic_Interrupts.
Update the documentation about the Ravenscar profile, following the
definition found in AI-249.
* sem_prag.adb: Use FIFO_Within_Priorities and Ceiling_Locking when
setting the Profile (Ravenscar). This must be done in addition to
setting the required restrictions.
* rtsfind.ads: Add the set of operations defined in package
Ada.Interrupts.

if -gnatc or -gnats is passed.
2004-05-27 Hristian Kirtchev <kirtchev@gnat.com>

a significant reference. Warnings are now properly emitted when a
discriminated type is not referenced.

record representation clause or record type discriminant does not
produce a reference to its corresponding entity. Warnings are now
properly emitted when deferred constants and record types are not
referenced.

-rnb - replace the original source without creating its backup copy
-c0 - do not format comments
2004-05-24 Geert Bosch <bosch@gnat.com>
* a-numaux-x86.adb (Reduce): Reimplement using an approximation of Pi
with 192 bits of precision, sufficient to reduce a double-extended
arguments X with a maximum relative error of T'Machine_Epsilon, for X
in -2.0**32 .. 2.0**32.
(Cos, Sin): Always reduce arguments of 1/4 Pi or larger, to prevent
reduction by the processor, which only uses a 68-bit approximation of
Pi.
(Tan): Always reduce arguments and compute function either using
the processor's fptan instruction, or by dividing sin and cos as needed.
2004-05-24 Doug Rupp <rupp@gnat.com>
