PR ada/18434
* types.ads: Include All_Checks in Suppress_Array
* checks.adb (Check_Needed): Remove kludge for a/=b rewritten as
not(a=b), since we no longer do this rewriting, and hence it is not
needed.
(Elaboration_Checks_Suppressed): Add special casing to
deal with different cases of static and dynamic elaboration checks (all
checks does not count in the first case, but does in the second).
(Expr_Known_Valid): Do not assume that the result of any arbitrary
function call is valid, since this is not the case.
(Ensure_Valid): Do not apply validity check to a real literal
in a universal or fixed context
* exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
elementary types using the operator in standard. It is cleaner not to
modify the programmers intent, especially in the case of floating-point.
(Rewrite_Comparison): Fix handling of /= (this was always wrong, but
it did not matter because we always rewrote a/=b to not(a=b).
(Expand_Allocator_Expression): For an allocator expression whose nominal
subtype is an unconstrained packed type, convert the expression to its
actual constrained subtype.
Implement warning for <= or >= where < or > not possible
Fix to Vax_Float tests (too early in many routines, causing premature
Vax_Float expansions.
* sem_prag.adb (Analyze_Pragma, case Obsolescent): Allow this pragma
to be used with packages and generic packages as well as with
subprograms.
(Suppress): Set All_Checks, but not Elaboration_Check, for case
of pragma Suppress (All_Checks)
(Analyze_Pragma, case Warnings): Implement first argument allowed to be
a string literal for precise control over warnings.
Avoid raise of pragma in case of unrecognized pragma and just return
instead.
* sem_prag.ads: Minor reformatting
* switch-c.adb (Scan_Front_End_Switches): Replace "raise Bad_Switch;"
with call to new procedure Bad_Switch. Call Scan_Pos with new parameter
Switch. Do not handle any exception.
Include -gnatwx as part of -gnatg (warn on redundant parens)
Allow optional = after -gnatm
(Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
longer sets Elaboration_Checks.
Code to set warning mode moved to Sem_Warn
so that it can be shared by pragma processing.
* s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if
statement.
* s-taprop-solaris.adb:
Change some <= to =, to avoid new warning
* a-exexda.adb, prj-proc.adb:
Fix obvious typo (Num_Tracebacks compared <= 0 instead of < 0)
Fix obvious typo (Total_Errors_Detected <= 0 should be = 0)
2005-11-14 Robert Dewar <dewar@adacore.com>
* exp_vfpt.adb: Handle /= case

* s-tassta.adb (Create_Task): Move the code in charge of resetting the
deferral level, when abort is not allowed, to a later stage (the
Task_Wrapper).
(Task_Wrapper): If Abort is not allowed, reset the deferral level since
it will not get changed by the generated code. It was previously done
in Create_Task.
2005-11-14 Thomas Quinot <quinot@adacore.com>
Olivier Hainque <hainque@adacore.com>
Eric Botcazou <ebotcazou@adacore.com>
* decl.c:
Factor common code to build a storage type for an unconstrained object
from a fat or thin pointer type and a constrained object type.
(annotate_value): Handle BIT_AND_EXPR.
(annotate_rep): Don't restrict the back annotation of inherited
components to the type_annotate_only case.
(gnat_to_gnu_entity) <E_Array_Type>: Do not invoke create_type_decl if
we are not defining the type.
<E_Record_Type>: Likewise.
(gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
to get advantage of the new maybe_stabilize_reference interface, to
ensure that what we reference is indeed stabilized instead of relying
on assumptions on what the stabilizer does.
(gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
type imported through a limited_with clause, use its non-limited view.
(Has_Stdcall_Convention): New macro, to centralize the Windows vs others
differentiation.
(gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
of #if sections + explicit comparisons of convention identifiers.
(gnat_to_gnu_entity) <E_Variable>: Decrement force_global if necessary
before early-returning for certain types when code generation is
disabled.
(gnat_to_gnu_entity) <object>: Adjust comment attached to the
nullification of gnu_expr we do for objects with address clause and
that we are not defining.
(elaborate_expression_1): Do not create constants when creating
variables needed by the debug info: the dwarf2 writer considers that
CONST_DECLs is used only to represent enumeration constants, and emits
nothing for them.
(gnat_to_gnu_entity) <object>: When turning a non-definition of an
object with an address clause into an indirect reference, drop the
initializing expression.
Include "expr.h".
(STACK_CHECK_BUILTIN): Delete.

(STACK_CHECK_MAX_FRAME_SIZE): Likewise.
(STACK_CHECK_MAX_VAR_SIZE): Likewise.
(gnat_to_gnu_entity): If gnat_entity is a renaming, do not mark the tree
corresponding to the renamed object as ignored for debugging purposes.
* trans.c (tree_transform, case N_Attribute_Reference, case Attr_Size &
related): For a prefix that is a dereference of a fat or thin pointer,
if there is an actual subtype provided by the front-end, use that
subtype to build an actual type with bounds template.
(tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
is provided by the front-end, use that subtype to compute the size of
the deallocated object.
(gnat_to_gnu): When adding a statement into an elaboration procedure,
check for a potential violation of a No_Elaboration_Code restriction.
(maybe_stabilize_reference): New function, like gnat_stabilize_reference
with extra arguments to control whether to recurse through non-values
and to let the caller know if the stabilization has succeeded.
(gnat_stabilize_reference): Now a simple wrapper around
maybe_stabilize, for common uses without restriction on lvalues and
without need to check for the success indication.
(gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
pass false instead of 0 as the FORCE argument which is a bool.
(Identifier_to_gnu): Remove checks ensuring that an renamed object
attached to a renaming pointer has been properly stabilized, as no such
object is attached otherwise.
(call_to_gnu): Invoke create_var_decl to create the temporary when the
function uses the "target pointer" return mechanism.
Reinstate conversion of the actual to the type of the formal
parameter before any other specific treatment based on the passing
mechanism. This turns out to be necessary in order for PLACEHOLDER
substitution to work properly when the latter type is unconstrained.
* gigi.h (build_unc_object_type_from_ptr): New subprogram, factoring a
common pattern.
(maybe_stabilize_reference): New function, like gnat_stabilize_reference
with extra arguments to control whether to recurse through non-values
and to let the caller know if the stabilization has succeeded.
* utils2.c (gnat_build_constructor): Only sort the fields for possible
static output of record constructor if all the components are constant.
(gnat_build_constructor): For a record type, sort the list of field
initializers in increasing bit position order.
Factor common code to build a storage type for an unconstrained object
from a fat or thin pointer type and a constrained object type.
(build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
types variants, and process special cases of VIEW_CONVERT expressions
as their NOP_EXPR counterpart to ensure we get to the
CORRESPONDING_VARs associated with CONST_DECls.
(build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
on the right-hand side.
* utils.c (build_unc_object_type_from_ptr): New subprogram, factoring
a common pattern.
(convert) <VIEW_CONVERT_EXPR>: Return the inner operand directly if we
are converting back to its original type.
(convert) <JM input>: Fallthrough regular conversion code instead of
extracting the object if converting to a type variant.
(create_var_decl): When a variable has an initializer requiring code
generation and we are at the top level, check for a potential violation
of a No_Elaboration_Code restriction.
(create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
SIZE and SIZE_UNIT which we need for later back-annotations.
* utils.c: (convert) <STRING_CST>: Remove obsolete code.
<VIEW_CONVERT_EXPR>: Do not lift the conversion if the target type
is an unchecked union.
(pushdecl): Set DECL_NO_STATIC_CHAIN on imported nested functions.
(convert) <VIEW_CONVERT_EXPR>: When the types have the same
main variant, just replace the VIEW_CONVERT_EXPR.
<UNION_TYPE>: Revert 2005-03-02 change.
* repinfo.h, repinfo.ads: Add tcode for BIT_AND_EXPR.
* repinfo.adb (Print_Expr, Rep_Value): Handle Bit_And_Expressions.

Thomas Quinot <quinot@adacore.com>
* exp_ch5.adb (Expand_N_Assignment_Statement, Tagged_Case): For an
assignment of a value of a tagged type that has been rewritten to a
block statement, it is known by construction that no checks are
necessary for the statements within the block: analyze it with checks
suppressed.
(Expand_N_If_Statement): When killing a dead then-branch in an
if-statement that has elsif_parts, recompute the Current_Value node
for any entity whose value is known from the condition of the first
elsif_part.
(Expand_N_Return_Statement): When returning a mutable record, convert
the return value into its actual subtype in order to help the backend
to return the actual size instead of the maximum. This is another
aftermath of not returning mutable records on the sec-stack anymore.

by spawnve is a process handle, no need to convert. Add a parameter
close to control wether the process handle must be closed.
(__gnat_waitpid): Fix implementation, the pid returned by spawnve is
a process handle, not need to convert.
(__gnat_kill) [*]: Add dummy parameter close to match the Win32 spec.

waitpid() is using it.
(Send_Signal): Release the process handle.
2005-11-14 Robert Dewar <dewar@adacore.com>
* exp_fixd.adb: Use Universal_Real instead of Long_Long_Float when we
need a high precision float type for the generated code (prevents
gratuitous Vax_Float stuff when pragma Float_Representation (Vax_Float)
used).
* exp_imgv.adb: Use Universal_Real instead of Long_Long_Float when we
need a high precision float type for the generated code (prevents
gratuitous Vax_Float stuff when pragma Float_Representation (Vax_Float)
used).
