c
(
__gnat_portable_spawn
):
Fix
cast
of
spawnvp
third
parameter
to
avoid
warnings
.
Add
also
a
cast
to
kill
another
warning
.
(
win32_no_block_spawn
):
Initialize
CreateProcess
's dwCreationFlags
parameter with the priority class of the parent process instead of
always using the NORMAL_PRIORITY_CLASS.
(__gnat_dup): New function.
(__gnat_dup2): New function.
(__gnat_is_symbolic_link): Enable the effective body of this
function when __APPLE__ is defined.
* g-os_lib.ads, g-os_lib.adb (Spawn): Two new procedures.
Update comments.
2004-11-18 Olivier Hainque <hainque@adacore.com>
* 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.
(struct attrib): Rename "arg" component as "args", since GCC expects a
list of arguments in there.
* raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
corresponding objects exported by a-exexpr, instead of hardcoded dummy
addresses.
* trans.c (Exception_Handler_to_gnu_zcx): Use the address of
others_decl and all_others_decl instead of hardcoded dummy addresses
to represent "others" and "all others" choices, which is cleaner and
more flexible with respect to the possible eh pointer encoding policies.
* utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
(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:
Minor reformatting througout (including new function specs)
Add ??? comments asking for clarification.
2004-11-18 Thomas Quinot <quinot@adacore.com>
* butil.ads, butil.adb, bindgen.adb (Get_Unit_Name_String): Remove
incomplete duplicate implementation of this subprogram from butil.
2004-11-18 Thomas Quinot <quinot@adacore.com>
* exp_dist.adb (Build_RPC_Receiver_Body): New subprogram. This
procedures factors the common processing for building an RPC receiver
for an RCI package or an RACW type.
Stylistic cleanup: change '
/=
Empty
' to '
Present
()
'; move body of
Build_Remote_Subprogram_Proxy_Type into proper alphabetical order.
(Get_PCS_Name): New subprogram. Returns the name of the PCS currently
in use.
(Specific_Add_RACW_Features): New subprogram. PCS-specific part of
Add_RACW_Features.
(Specific_Add_RAST_Features): New subprogram. PCS-specific part of
Add_RAST_Features.
(Assign_Subprogram_Identifier): New subprogram. Provision for assigning
distribution subprogram identifiers that are either subprogram numbers
or strings.
(Get_Subprogram_Ids): New subprogram. Retrieve both the numeric and
string distribution identifiers assigned to a given subprogram.
(Get_Subprogram_Id): Reimplement in terms of Get_Subprogram_Ids.
(Add_RAS_Dereference_TSS): Add comments.
(Build_General_Calling_Stubs): Note that the RACW_Type formal parameter
is not referenced yet because it will be used by the PolyORB DSA
implementation.
(Insert_Partition_Check): Remove fossile code.
(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.
* sem_dist.adb: Remove comment noting that RPC receiver generation
should be disabled for RACWs that implement RASs.
(Process_Partition_Id): Use new subprogram Get_Library_Unit_Name_String.
* sem_util.ads, sem_util.adb (Has_Stream): New function
(Get_Library_Unit_Name_String): New subprogram to retrieve the fully
qualified name of a library unit into the name buffer.
(Note_Possible_Modification): Generate a reference only
if the context comes from source.
* snames.ads (PCS_Names): New subtype corresponding to names of
supported implementations of the Partition Communication Subsystem
(PCS) (i.e. the runtime library support modules for the distributed
systems annex).
2004-11-18 Robert Dewar <dewar@adacore.com>
Ed Schonberg <schonberg@adacore.com>
* einfo.ads, einfo.adb: Remove Is_Psected flag, no longer used
(Has_Rep_Pragma): New function
(Has_Attribute_Definition_Clause): New function
(Record_Rep_Pragma): Moved here from sem_ch13.adb
(Get_Rep_Pragma): Remove junk kludge for Stream_Convert pragma
* sem_ch13.ads, sem_ch13.adb (Record_Rep_Pragma): Moved to einfo.adb
* 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.
* exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
that are functions return universal values, that have to be converted
to the context type.
Use new Make_String_Literal function with string.
(Get_Stream_Convert_Pragma): New function, replaces the use of
Get_Rep_Pragma, which had to be kludged to work in this case.
* freeze.adb: Use new Has_Rep_Pragma function
* exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
function with string.
Use new Has_Rep_Pragma function.
* tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
string argument.
2004-11-18 Robert Dewar <dewar@adacore.com>
* errout.ads, errout.adb: (First_Sloc): New function
* par-ch5.adb (P_Condition): Check for redundant parens is now a style
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,
stylesw.adb: Add Style_Check_Xtra_Parens
* usage.adb: Add line for -gnatyx (check extra parens)
* vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
2004-11-18 Ed Schonberg <schonberg@adacore.com>
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
similar
private
type
whose
full
view
has
discriminants
.
(
Analyze_Object_Declaration
):
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
.
