* ug_words, gnat_ugn.texi: Added alpha-ivms transitioning section to
porting guide chapter (vms version).
Revised doc title (removed "for native platforms") and subtitle.
Add discussion on warning flag for obsolescent features. First we
note that it applies to obsolete GNAT features, which was previously
omitted. Second we contrast the behavior with that of the new
Ada 2005 AI-368 restriction No_Obsolescent_Features.
Preliminary rewriting of GNAT & libraries chapter in order to take
into account default project locations & new project manager
capabilities.
* cstand.adb (Create_Operators): Clean up format and documentation of
unary and binary operator result tables. No change in code, just
reformatting and addition of comments.
* errout.ads, gnatfind.adb, s-maccod.ads, sem.adb,
sem_ch2.adb: Minor reformatting
* atree.ads, elists.ads, lib.ads, namet.ads, nlists.ads, repinfo.ads,
sinput.ads, stringt.ads, uintp.ads, urealp.ads: Minor clarification to
comments for Tree_Read and Tree_Write.
* exp_attr.ads: Minor reformatting.
* comperr.adb (Compiler_Abort): Add specialized message for GAP
versions.
* exp_pakd.adb (Create_Packed_Array_Type): Add a guard to check
whether the ancestor type is private, as may be the case with nested

* s-tasini.ads, s-tasini.adb (Undefer_Abortion): Handle case of
Self_Id.Deferral_Level = 0.
(Do_Pending_Action): Move this function to the spec.
* s-tasren.adb (Selective_Wait [Terminate_Selected]): Call
Do_Pending_Action explicitely when needed, in case we're using
No_Abort restrictions.
* s-tassta.adb (Create_Task): If Abort is not allowed, reset the
deferral level since it will not get changed by the generated code.
Keeping a default value of 1 would prevent some operations (e.g.
select or delay) to proceed successfully.
From-SVN: r92851
* sem_ch4.adb (Has_Fixed_Op): New predicate in Check_Arithmetic_Pair,
to determine whether one of the operands is a fixed-point type for
which a user-defined multiplication or division operation might be
defined.
* sem_res.adb (Valid_Conversion): The legality rules for conversions
of access types are symmetric in Ada 2005: either designated type can
be unconstrained.
From-SVN: r92849
* sem_ch12.adb (Analyze_Package_Instantiation): Create a separate node
to use as the defining identifier for a formal package.
(Remove_Parent): If the instance takes place within (an instance of)
a sibling, preserve private declarations of common parent.
From-SVN: r92848
* s-arit64.adb (Double_Divide): Put back changes that got accidentally
removed during the previous update (test properly for case of dividing
largest negative number by -1, which generates overflow).

darwin port by using proper type definitions from header files.
Use SIGTERM instead of SIGABRT for SIGADAABORT.

libraries when Unique_Compile is True (-u switch).
(Gnatmake): ditto.
From-SVN: r92843
* exp_ch7.ads (Make_Final_Call): Rewrite comment (was incorrectly
copied from Make_Init_Call).
* exp_strm.adb (Build_Mutable_Record_Read_Procedure): Do component
reads and assignments on a temporary variable declared with appropriate
discriminants.
From-SVN: r92838
* exp_dist.adb:
Declare subprogram index in Build_RPC_Receiver_Body, to reduce the
amount of PCS-specific code in RACW stubs generation.
(Copy_Specification): Set Etype on copied formal parameter entities, as
this information is needed for PolyORB stubs generation.
(PolyORB_Support.Build_Subprogram_Receiving_Stubs): Remove unused
variable Dynamic_Async.

PCS-specific.

bounds can be negative, and must be declared Int, not Nat.
* sem_elim.adb (Line_Num_Match): Correct wrong code when index in an
array is checked after using the index in the array.

integer.
From-SVN: r92834
* decl.c (compatible_signatures_p): New function. The intended purpose
is to check if two function signatures for a call-site and a callee are
compatible enough for the call to be valid. The underlying purpose is
to check if a call to a mapped builtin is using the right interface.
The current code actually does not check antyhing - this a placeholder
for future refinements.
(gnat_to_gnu_entity) <E_Subprogram_Call>: Add preliminary bits to handle
builtin calls for convention Intrinsic.
* gigi.h (builtin_decl_for): Declare (new function).

a-numaux-darwin.ads and a-numaux-darwin.adb
Enable mlib-tgt-lynxos.adb on lynxos.
* Make-lang.in: Remove rules for gpr2make.
When generating sdefault.adb, do not call Relocate_Path
on S3 for function Target_Name, as it is not a path.
Remove references to gnatmem and libaddr2line.
* a-numaux-darwin.ads, a-numaux-darwin.adb, g-soccon-darwin.ads: New
files.
From-SVN: r92831

attribute Mod.

* ali.ads, ali.adb: Adjustments for reading new No_Dependence
restrictions lines.
(Scan_ALI): When finding an unexpected character on an R line, raise
exception Bad_R_Line, instead of calling Fatal_Error, so that, when

ALI file continues with the next line. Also, when Bad_R_Line is raised
and Ignore_Errors is True, skip to the end of le line.
