2009-06-24  Emmanuel Briot  <briot@adacore.com>

	prj-nmsc.adb, prj-env.adb (File_Name_Data): removed
	(Spec_Or_Body): now a subtype of Source_Kind, to avoid using two
	different vocabularies for similar concepts (Impl/Body_Part and
	Spec/Specification).
	(Unit_Data): now points directly to a Source_Id, rather than duplicating
	some of the information in File_Name_Data. This also saves a bit of
	memory. However, since we are now using a pointer we need to test
	for null explicitly in several places of the code

2009-06-24  Javier Miranda  <miranda@adacore.com>

	* exp_ch4.adb (Expand_N_Type_Conversion): return immediately

2009-06-23  Hristian Kirtchev  <kirtchev@adacore.com>

	* sem_attr.adb: Add with and use clauses for Sem_Ch10.
	(Check_Not_Incomplete_Type): Minor reformatting. Retrieve the root type

	retrieve its non-limited view.

	* sem_ch10.adb (Has_With_Clause): Move the spec and body of the
	subprogram to top package level from Intall_Limited_Withed_Unit.

2009-06-23  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch10.adb (Remove_Limited_With_Clause): Clean up code that handles
	incomplete type declarations. Previous code was potentially quadratic

	* prj-nmsc.adb (Locate_Directory): Remove unused parameters, and add
	support for returning the directory even if it doesn't exist. This is
	used for the object directory, since we are always setting it to a

	relative name for the sake of external tools that might depend on it.
	(Check_Library_Attributes): When Project.Library_Dir is known, check
	that the directory exists.

2009-05-06  Ed Schonberg  <schonberg@adacore.com>

	* rtsfind.adb, rtsfind.ads, exp_dist.adb, exp_dist.ads
	(Exp_Dist.Build_TC_Call, Build_From_Any_Call, Build_To_Any_Call):

	address of Iovec (it's Msg_Iov, not Msg_Iov'Address).
	(GNAT.Sockets.Thin.C_Sendto, GNAT.Sockets.Thin.C_Recvfrom): Use a
	System.Address for the To parameter instead of a Sockaddr_In_Access, to
	achieve independance from AF_INET family, and also to allow this
	parameter to be retrieved from a Msghdr for the Windows case where
	these routines are used to implement C_Sendmsg and C_Recvmsg.

	* exp_ch9.ads, exp_ch9.adb (Build_Wrapper_Spec): Use source line of
	primitive operation, rather than source line of synchronized type, when
	building the wrapper for a primitive operation that overrides an
	operation inherited from a progenitor, to improve the error message on
	duplicate declarations.

2009-04-29  Gary Dismukes  <dismukes@adacore.com>

	* exp_ch3.adb (Stream_Operation_OK): Return True for limited interfaces

	operation is a body without previous spec, update the list of
	primitive operations to ensure that cross-reference information is
	up-to-date.

	* sem_ch12.adb (Build_Instance_Compilation_Unit_Nodes): When creating a
	new compilation unit node for the instance declaration, keep the
	context items of the original unit on it, so that the context of the
	instance body only holds the context inherited from the generic body.

2009-04-29  Bob Duff  <duff@adacore.com>

	* sem_res.adb: Minor comment fix.

2009-04-29  Thomas Quinot  <quinot@adacore.com>

	* sem_elim.adb: Minor reformatting

2009-04-29  Ed Schonberg  <schonberg@adacore.com>

	* exp_aggr.adb (Convert_To_Positional): if the current unit is a
	predefined unit, allow arbitrary number of components in static
	aggregate, to ensure that the same level of constant folding applies
	for Ada 95 and Ada 05 versions of the file.

2009-04-29  Ed Schonberg  <schonberg@adacore.com>

	* sem_elim.adb (Check_Eliminated): Handle new improved eliminate

2009-04-29  Matteo Bordin  <bordin@adacore.com>

	* s-stausa.ads: Changed visibility of type Task_Result: moved to

	This is for future improvement and to build a public API on top of it.
	Changed record components name of type Task_Result to reflect the new
	way of reporting. 

	* s-stausa.adb: Actual_Size_Str changed to reflect the new way of

2009-04-29  Thomas Quinot  <quinot@adacore.com>

	* sem_res.adb (Static_Concatenation): An N_Op_Concat with static

	* sem_util.adb: Minor reformatting

	* sem_ch12.adb (Save_References): When propagating semantic information
	from generic copy back to generic template, for the case of an
	identifier that has been rewritten to an explicit dereference whose
	prefix is either an object name or a parameterless funcion call
	denoting a global object or function, properly capture the denoted
	global entity: perform the corresponding rewriting in the template,
	and point the rewritten identifier to the correct global entity (not
	to the associated identifier in the generic copy).

2009-04-29  Robert Dewar  <dewar@adacore.com>

	* rtsfind.adb, prj-env.adb: Minor reformatting
	Minor code reorganization

2009-04-29  Emmanuel Briot  <briot@adacore.com>

	is given as argument, as might happen in gnatmake.

2009-04-29  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch3.adb (Check_Abstract_Overriding): Improve error message when
	an abstract operation of a progenitor is not properly overridden by an
	operation of a derived synchronized type.

2009-04-29  Robert Dewar  <dewar@adacore.com>

	* mlib-prj.adb, mlib-tgt.adb, mlib-tgt.ads, prj-nmsc.adb,
	prj-proc.adb: Minor reformatting
	Minor code reorganization

2009-04-29  Bob Duff  <duff@adacore.com>

	* exp_ch7.adb (Build_Final_List): For an access type that designates a
	Taft Amendment type, if the access type needs finalization, make sure
	the implicit with clause for List_Controller occurs on the package spec.

	* rtsfind.adb (Text_IO_Kludge): Fine tune the creation of implicit
	with's created for the pseudo-children of Text_IO and friends. In
	particular, avoid cycles, such as Ada.Wide_Text_IO.Integer_IO and
	Ada.Text_IO.Integer_IO both with-ing each other.

	* sem.adb (Walk_Library_Items): Suppress assertion failure in certain
	oddball cases when pragma Extend_System is used.

	* sem_ch12.adb (Get_Associated_Node): Prevent direct 'with' cycles in
	the case where a package spec instantiates a generic whose body with's
	this package, so Walk_Library_Items won't complain about cyclic with's.

2009-04-29  Emmanuel Briot  <briot@adacore.com>

	* gnatcmd.adb, prj-proc.adb, make.adb, mlib-prj.adb, prj.adb, prj.ads,
	prj-pp.adb, prj-pp.ads, makeutl.adb, clean.adb, prj-nmsc.adb,
	mlib-tgt.adb, mlib-tgt.ads, prj-util.adb, prj-env.adb, prj-env.ads
	(Project_Id): now a real pointer to Project_Data, instead of an index
	into the Projects_Table. This simplifies the API significantly, avoiding
	extra lookups in this table and the need to pass the Project_Tree_Ref
	parameter in several cases

2009-04-29  Nicolas Setton  <setton@adacore.com>

	* gcc-interface/Makefile.in: Produce .dSYM files for shared libs on
	darwin.

2009-04-25  Eric Botcazou  <ebotcazou@adacore.com>

	* gcc-interface/decl.c (gnat_to_gnu_entity) <E_Array_Subtype>: Put
	back kludge.

2009-04-24  Robert Dewar  <dewar@adacore.com>

	* mlib-prj.adb, prj-env.adb, prj-nmsc.adb, prj-proc.adb, make.adb,
	clean.adb: Minor reformatting.
	Minor code reorganization and message improvement.

2009-04-24  Emmanuel Briot  <briot@adacore.com>

	* prj-proc.adb, prj.adb, prj.ads, prj-nmsc.adb, prj-nmsc.ads
	(Alternate_Languages): now implemented as a malloc-ed list rather
	than through a table.

2009-04-24  Thomas Quinot  <quinot@adacore.com>

	* sem_res.adb (Static_Concatenation): Simplify predicate to make it
	accurately handle cases such as "lit" & "lit" and
	"lit" & static_string_constant

2009-04-24  Emmanuel Briot  <briot@adacore.com>

	* prj-proc.adb, make.adb, mlib-prj.adb, prj.adb, prj.ads, clean.adb,
	prj-nmsc.adb, prj-env.adb (Project_List_Table, Project_Element):
	removed. Lists of projects are now implemented via standard malloc
	rather than through the table.

2009-04-24  Thomas Quinot  <quinot@adacore.com>

	* sem_ch12.adb: Minor reformatting

	* g-trasym.adb: Minor reformatting

	* exp_ch6.adb: Minor reformatting

2009-04-24  Robert Dewar  <dewar@adacore.com>

	* layout.adb (Layout_Type): For packed array type, copy unset
	size/alignment fields from the referenced Packed_Array_Type.

2009-04-24  Bob Duff  <duff@adacore.com>

	* lib-load.adb (Make_Instance_Unit): Revert previous change, no
	longer needed after sem_ch12 changes.

	* sem.adb (Walk_Library_Items): Include with's in some debugging
	printouts.

2009-04-24  Emmanuel Briot  <briot@adacore.com>

	* prj.ads, prj-nmsc.adb (Unit_Project): removed, since in fact we were
	only ever using the Project field.

2009-04-24  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch12.adb (Build_Instance_Compilation_Unit_Nodes): Do not set
	Body_Required on the generated compilation node. The new node is linked
	to its body, but both share the same file, so we do not set this flag
	on the new unit so as not to create a spurious dependency on a
	non-existent body in the ali file for the instance.

2009-04-24  Robert Dewar  <dewar@adacore.com>

	* make.adb: Minor reformatting

2009-04-24  Emmanuel Briot  <briot@adacore.com>

	* prj.adb, prj.ads, prj-nmsc.adb (Check_File, Record_Ada_Source,
	Add_Source): merge some code between those. In particular change where
	file normalization is done to avoid a few extra calls to
	Canonicalize_File_Name. This also removes the need for passing
	Current_Dir in a number of subprograms.

2009-04-24  Bob Duff  <duff@adacore.com>

	* lib-load.adb (Make_Instance_Unit): In the case where In_Main is
	False, assign the correct unit to the Cunit field of the new table
	entry. We want the spec unit, not the body unit.

	* rtsfind.adb (Make_Unit_Name, Maybe_Add_With): Simplify calling
	interface for these.
	(Maybe_Add_With): Check whether we're trying to a with on the current
	unit, and avoid creating such directly self-referential with clauses.
	(Text_IO_Kludge): Add implicit with's for the generic pseudo-children of
	[[Wide_]Wide_]Text_IO. These are needed for Walk_Library_Items,
	and matches existing comments in the spec.

	* sem.adb (Walk_Library_Items): Add various special cases to make the
	assertions pass.

	* sem_ch12.adb (Build_Instance_Compilation_Unit_Nodes): Use Body_Cunit
	instead of Parent (N), for uniformity.

2009-04-24  Robert Dewar  <dewar@adacore.com>

	* errout.ads: Minor reformatting

2009-04-24  Emmanuel Briot  <briot@adacore.com>

	behavior when the project includes sources from multiple languages

2009-04-24  Vincent Celier  <celier@adacore.com>

	* prj.adb (Has_Foreign_Sources): Returns True in Ada_Only mode if there
	is a language other than Ada declared.

	* makeutl.adb (Linker_Options_Switches): Call For_All_Projects with
	Imported_First set to True.

2009-04-24  Ed Schonberg  <schonberg@adacore.com>

	* sem_res.adb: additional optimization to inhibit creation of
	redundant transient scopes.

2009-04-24  Bob Duff  <duff@adacore.com>

	* rtsfind.ads: Minor comment fix

2009-04-24  Emmanuel Briot  <briot@adacore.com>

	* prj-proc.adb, prj-nmsc.adb (Find_Ada_Sources,
	Get_Path_Name_And_Record_Ada_Sources): merged, since these were
	basically doing the same work (for explicit or implicit sources).
	(Find_Explicit_Sources): renamed to Find_Sources to better reflect its
	role. Rewritten to share some code (testing that all explicit sources
	have been found) between ada_only and multi_language modes.

2009-04-24  Jerome Lambourg  <lambourg@adacore.com>

	* sem_prag.adb (Check_Form_Of_Interface_Name): Allow space in Ext_Name
	for CLI imported types.
	(Analyze_Pragma): Allow CIL or Java imported functions returning
	access-to-subprogram types.

2009-04-24  Emmanuel Briot  <briot@adacore.com>

	* make.adb, prj.adb, prj.ads, makeutl.adb, makeutl.ads:
	(Project_Data.Dir_Path): field removed, since it can be computed
	directly from .Directory, and is needed only once when processing the
	project is buildgpr.adb or make.adb

2009-04-24  Robert Dewar  <dewar@adacore.com>

	* prj-env.adb, prj-proc.adb, prj.adb, prj.ads,
	rtsfind.adb: Minor reformatting.
	Minor code reorganization

2009-04-24  Arnaud Charlet  <charlet@adacore.com>

	* mlib-prj.adb: Use friendlier english identifier.

	* gnatcmd.adb, make.adb: Use better english identifiers.

2009-04-24  Robert Dewar  <dewar@adacore.com>

	* clean.adb: Minor reformatting

2009-04-24  Robert Dewar  <dewar@adacore.com>

	* einfo.adb (OK_To_Rename): New flag

	* einfo.ads (OK_To_Rename): New flag

	* exp_ch3.adb (Expand_N_Object_Declaration): Rewrite as renames if
	OK_To_Rename set.

	* exp_ch4.adb (Expand_Concatenate): Mark temp variable OK_To_Rename

	* sem_ch7.adb (Uninstall_Declarations): Allow for renames from
	OK_To_Rename.

2009-04-24  Emmanuel Briot  <briot@adacore.com>

	* prj-proc.adb, make.adb, mlib-prj.adb, prj.adb, prj.ads, makeutl.adb,
	clean.adb, prj-nmsc.adb, prj-env.adb, prj-env.ads (Project_Data.Seen):
	field removed. This is not a property of the
	project, just a boolean used to traverse the project tree, and storing
	it in the structure prevents doing multiple traversal in parallel.
	(Project_Data.Checked): also removed, since it was playing the same role
	as Seen when we had two nested loops, and this is no longer necessary
	(For_All_Imported_Projects): removed, since in fact there was already
	the equivalent in For_Every_Project_Imported. The latter was rewritten
	to use a local hash table instead of Project_Data.Seen
	Various loops were rewritten to use For_Every_Project_Imported, thus
	removing the need for Project_Data.Seen. This avoids a lot of code
	duplication

2009-04-24  Ed Schonberg  <schonberg@adacore.com>

	* sem_res.adb (Resolve_Actuals): Do not create blocks around code
	statements, even though the actual of the call is a concatenation,
	because the argument is static, and we want to preserve warning
	messages  about sequences of code statements that are not marked
	volatile.

	* sem_warn.adb: remove obsolete comment about warning being obsolete

	* s-tasren.adb (Task_Do_Or_Queue): If a timed entry call is being
	requeued and the delay has expired while within the accept statement
	that executes the requeue, do not perform the requeue and indicate that
	the timed call has been aborted.

2009-04-24  Emmanuel Briot  <briot@adacore.com>

	* mlib-prj.adb, prj.adb, prj.ads, prj-nmsc.adb, prj-env.adb
	(Has_Ada_Sources, Has_Foreign_Sources): new subprograms
	(Project_Data.Ada_Sources_Present, Foreign_Sources_Present): removed,
	since they can be computed from the above.

2009-04-24  Vincent Celier  <celier@adacore.com>

	* gnatcmd.adb: Call Prj.Env.Initialize with the Project_Tree

	* prj-env.adb: Move all global variables to the private part of the
	project tree data.
	Access these new components instead of the global variables no longer
	in existence.
	(Add_To_Path): New Project_Tree_Ref parameter, to access the new
	components that were previously global variables.

	* prj-env.ads (Initialize): New Project_Tree_Ref parameter
	(Set_Mapping_File_Initial_State_To_Empty): New Project_Tree_Ref
	parameter.

	* prj-nmsc.adb (Compute_Unit_Name): New Project_Tree_Ref parameter to
	be able to call Set_Mapping_File_Initial_State_To_Empty with it.

	* prj.adb (Initialize): Do not call Prj.Env.Initialize
	(Reset): Do not call Prj.Env.Initialize. Instead, initialize the new
	components in the private part of the project tree data.

	* prj.ads (Private_Project_Tree_Data): new components moved from
	Prj.Env: Current_Source_Path_File, Current_Object_Path_File,
	Ada_Path_Buffer, Ada_Path_Length, Ada_Prj_Include_File_Set,
	Ada_Prj_Objects_File_Set, Fill_Mapping_File.

2009-04-24  Vincent Celier  <celier@adacore.com>

	* opt.ads (Unchecked_Shared_Lib_Imports): New Boolean flag.

	* prj-nmsc.adb (Check_Library): No error for imports by shared library
	projects, when --unchecked-shared-lib-imports is used.

2009-04-24  Robert Dewar  <dewar@adacore.com>

	* sem_ch7.adb: Minor reformatting

2009-04-24  Tristan Gingold  <gingold@adacore.com>

	* s-osinte-darwin.adb, s-osinte-darwin.ads: lwp_self now returns the
	mach thread id.

2009-04-24  Emmanuel Briot  <briot@adacore.com>

	* prj-env.adb, prj-env.ads (Body_Path_Name_Of, Spec_Path_Name_Of,
	Path_Name_Of_Library_Unit_Body): rEmove unused subprograms.
	(For_All_Imported_Projects): new procedure
	(For_All_Source_Dirs, For_All_Object_Dirs): Rewritten based on the
	above rather than duplicating code.

2009-04-24  Emmanuel Briot  <briot@adacore.com>

	* prj-proc.adb, prj.adb, prj.ads, prj-nmsc.adb, prj-env.adb
	(Source_Id, Source_Data): use a real list to store sources rather than
	using an external table to store the elements. This makes code more
	efficient and more readable.

2009-04-24  Emmanuel Briot  <briot@adacore.com>

	* prj-proc.adb, prj.adb, prj.ads, prj-nmsc.adb, prj-env.adb
	(Source_Iterator): new type.
	This removes the need for having the sources on three different
	lists at the project tree, project and language level. They are now
	on a single list.

2009-04-24  Emmanuel Briot  <briot@adacore.com>

	* gnatcmd.adb, prj.adb, prj.ads: Remove unused entities

	Check_Infinite_Loop_Warning.

	* sem_warn.adb (Check_Infinite_Loop_Warning): If the local variable
	tested in the while loop is a renaming, do not warn. Otherwise, we get
