access-to-subprogram type.
* rtsfind.ads: Add new runtime library entities and names for PolyORB
DSA.

instead, which has the same behaviour here since we never pass it a
NULL pointer.
* link.c (run_path_option, Solaris case): Use -Wl, as for other
platforms.

from Mlib.Tgt to Mlib.

5sml-tgt.adb, 5vml-tgt.adb, 5zml-tgt.adb, 5wml-tgt.adb
(Linker_Library_Path_Option): Remove target-specific versions of this
subprogram, now implemented as a target-independent function in Mlib.

access to protected subprogram call
Replace_Anonymous_Access_To_Protected_Subprogram.
(Set_Actual_Subtypes): Code cleanup.
* sem_ch8.adb (Analyze_Object_Renaming): Remove un-necessary call to

subprogram call Replace_Anonymous_Access_To_Protected.
(Array_Type_Declaration): In case of access to protected subprogram call
Replace_Anonymous_Access_To_Protected_Subprogram.

Replace_Anonymous_Access_To_Protected_Subprogram.

already parsed the null-excluding part.
* par-ch3.adb (P_Subtype_Declaration): Code cleanup.
(P_Identifier_Declarations): Code cleanup and give support to renamings

already parsed by the caller.
(P_Access_Type_Definition): New formal that indicates if the caller has
already parsed the null-excluding part.
* par-ch6.adb (P_Formal_Part): Add the null-excluding parameter to the
call to P_Access_Definition.
2004-04-19 Geert Bosch <bosch@gnat.com>
* checks.adb (Apply_Float_Conversion_Check): New procedure to implement
the delicate semantics of floating-point to integer conversion.

2004-04-19 Ed Schonberg <schonberg@gnat.com>
* par-prag.adb (Source_File_Name_Project): Fix typo in error message.
* exp_ch9.adb (Expand_Access_Protected_Subprogram_Type): Call analyze
to decorate the access-to-protected subprogram and the equivalent type.
* checks.adb (Null_Exclusion_Static_Checks): Code cleanup. Give support
to anonymous access to subprogram types.
* exp_ch4.adb (Expand_N_In): Preserve Static flag before
constant-folding, for legality checks in contexts that require an RM
static expression.
* exp_ch6.adb (Expand_N_Function_Call): If call may generate large
temporary but stack checking is not enabled, increment serial number
to so that symbol generation is consistent with and without stack
checking.
* exp_util.ads, exp_util.adb (May_Generate_Large_Temp): Predicate is
independent on whether stack checking is enabled, caller must check
the corresponding flag.
* sem_ch3.adb (Constrain_Index): Index bounds given by attributes need
range checks.
(Build_Derived_Concurrent_Type): Inherit Is_Constrained flag from
parent if it has discriminants.

legal if this is the internal completion of a private untagged
derivation.

no constraint checks, because it corresponds to an existing object.

only to subprograms in the same declarative part, i.e. the same unit,
not the same scope.
* sem_res.adb (Valid_Conversion): In an instance or inlined body,
ignore type mismatch on a numeric conversion if expression comes from
expansion.
2004-04-19 Sergey Rybin <rybin@act-europe.fr>
* sem_elim.adb (Process_Eliminate_Pragma): Remove the processing for
Homonym_Number parameter, add processing for Source_Location parameter
corresponding.
(Check_Eliminated): Remove the check for homonym numbers, add the check
for source location traces.
* sem_elim.ads (Process_Eliminate_Pragma): Replace Arg_Homonym_Number
with Arg_Source_Location corresponding to the changes in the format of
the pragma.
* sem_prag.adb: (Analyze_Pragma): Changes in the processing of
Eliminate pragma corresponding to the changes in the format of the
pragma: Homonym_Number is replaced with Source_Location, two ways of
distinguishing homonyms are mutially-exclusive.
2004-04-19 Joel Brobecker <brobecker@gnat.com>
* get_targ.ads (Get_No_Dollar_In_Label): Remove.
* exp_dbug.adb (Output_Homonym_Numbers_Suffix): Remove use of
No_Dollar_In_Label, no longer necessary, as it is always True.
(Strip_Suffixes): Likewise.
2004-04-19 Gary Dismukes <dismukes@gnat.com>
* s-stalib.ads (type Exception_Code): Use Integer'Size for exponent of
modulus for compatibility with size clause on targets with 16-bit
Integer.
* layout.adb (Discrimify): In the case of private types, set Vtyp to
full type to fix type mismatches on calls to size functions for
discriminant-dependent array components.

* Makefile.in: Add VMS and Windows versions of
Ada.Directories.Validity package body.
* Makefile.rtl: Add a-direct and a-dirval

* make.adb (Scan_Make_Arg): Pass any -fxxx switches to gnatlink, not
just to the compiler.
2004-04-05 Robert Dewar <dewar@gnat.com>
* a-except.adb (Exception_Name_Simple): Make sure lower bound of
returned string is 1.
* ali-util.adb: Use proper specific form for Warnings (Off, entity)
* eval_fat.ads: Minor reformatting
* g-curexc.ads: Document that lower bound of returned string values
is always one.
* gnatlink.adb: Add ??? comment for previous change
(need to document why this is VMS specific)
* s-stoele.ads: Minor reformatting
* tbuild.ads: Minor reformatting throughout (new function specs)
* par-ch10.adb (P_Context_Clause): Handle comma instead of semicolon
after WITH.
* scng.adb: Minor reformatting
2004-04-05 Geert Bosch <bosch@gnat.com>
* eval_fat.adb (Machine): Remove unnecessary suppression of warning.
(Leading_Part): Still perform truncation to machine number if the
specified radix_digits is greater or equal to machine_mantissa.
2004-04-05 Javier Miranda <miranda@gnat.com>
* par-ch3.adb: Complete documentation of previous change
Correct wrong syntax documentation of the OBJECT_DECLARATION rule
(aliased must appear before constant).
* par-ch4.adb: Complete documentation of previous change.
* par-ch6.adb: Complete documentation of previous change.
* sinfo.ads: Fix typo in commment.
2004-04-05 Ed Schonberg <schonberg@gnat.com>
* sem_ch3.adb (Inherit_Components): If derived type is private and has
stored discriminants, use its discriminants to constrain parent type,
as is done for non-private derived record types.
* sem_ch4.adb (Remove_Abstract_Operations): New subprogram to implement
Ada 2005 AI-310: an abstract non-dispatching operation is not a
candidate interpretation in an overloaded call.
* tbuild.adb (Unchecked_Convert_To): Preserve conversion node if
expression is Null and target type is not an access type (e.g. a
non-private address type).
2004-04-05 Thomas Quinot <quinot@act-europe.fr>
* exp_ch6.adb (Rewrite_Function_Call): When rewriting an assignment
statement whose right-hand side is an inlined call, save a copy of the
original assignment subtree to preserve enough consistency for
Analyze_Assignment to proceed.
* sem_ch5.adb (Analyze_Assignment): Remove a costly copy of the
complete assignment subtree which is now unnecessary, as the expansion
of inlined call has been improved to preserve a consistent assignment
tree. Note_Possible_Modification must be called only
after checks have been applied, or else unnecessary checks will
be generated.
* sem_util.adb (Note_Possible_Modification): Reorganise the handling
of explicit dereferences that do not Come_From_Source:
- be selective on cases where we must go back to the dereferenced
pointer (an assignment to an implicit dereference must not be
recorded as modifying the pointer);
- do not rely on Original_Node being present (Analyze_Assignment
calls Note_Possible_Modification on a copied tree).
* sem_warn.adb (Check_References): When an unset reference to a pointer
that is never assigned is encountered, prefer '<pointer> may be null'
warning over '<pointer> is never assigned a value'.
2004-04-05 Ramon Fernandez <fernandez@gnat.com>
* tracebak.c: Change STOP_FRAME in ppc vxworks to be compliant with
the ABI.
2004-04-05 Olivier Hainque <hainque@act-europe.fr>
* 5gmastop.adb (Pop_Frame): Comment out the pragma Linker_Option for
libexc. We currently don't reference anything in this library and
linking it in triggers linker warnings we don't want to see.
* init.c: Update comments.
