This patch modifies the transient scope mechanism to prevent secondary stack
leaks during object initialization. The modifications are as follows:
1) Prior to this change, the secondary stack was never managed within type
initialization procedures, for reasons unknown. It is speculated that the
controlled type model used at that time may have influenced this decision.
The secondary stack is now managed within type initialization procedures
in order to recover the memory once individual components or whole objects
are initialized.
2) A transient scope now delegates the secondary stack management to an
enclosing scope if there is no suitable context to wrap. This ensures that
the requirement to manage the secondary stack is not lost when the scope was
established for that purpose in mind.
3) A previous mechanism which examined the definition of a type (recursively)
to determine whether the type will involve the secondary stack was removed
because a) the mechanism could not detect this need with certainty, and b) the
trigger for secondary stack usage is now moved to the resolution of function
calls, which is always accurate.

An implicit dereference freezes the corresponding designated type. Most
implicit dereferences are made explicit during expansion, but this is not the
case for a dispatching call where the the controlling parameter and the
corresponding controlling argument are access to a tagged type. In that case,
to enforce the rule that an expression function that is a completion freezes
type references within, we must locate controlling arguments of an access type
and freeze explicitly the corresponding designated type.

The compiler warns when a generic actual is a fixed-point type, because
arithmetic operations in the instance will use the predefined operations on
it, even if the type has user-defined primitive operations (unless formsl
surprograms for these operations appear in the generic). This patch refines
this warning to exclude the case where the formsal type is private, because
in this case there can be no suspicious arithmetic operastions in the generic
unit.

GNATprove was emitting spurious checks about objects of the File_Type being
uninitialized and there was no easy to fix that (those checks could only be
silenced by pragma Annotate or by hiding File_Type behind as SPARK wrapper).
Now the full view of File_Type is annotated with Default_Initial_Condition
and GNATprove knows that objects of that type are default-initialized. The
default initialization is implicitly defined in the Ada RM (as indeed
there is no procedure that would take an IN OUT parameter of that type).
Semantics of Ada programs shall not be affected by these annotations,
so no frontend test is provided. It only affects GNATprove.

This pach modifies the expansion related to initialization calls and secondary
stack usage to inspec the components of a type derived from Limited_Controlled
or Controlled. Previously controlled types were treated as never utilizing the
secondary stack, however this is not true because a controlled type may contain
a component initialized by a function which returns on the secondary stack.

This patch imposes a new check and rewrites existing ones to ensure operations
involving SS_Ptr do not cause an Integer overflow. The Default_Sec_Stack_Size
function was removed in the process to simplify System.Parameter.
SS_Ptr was derived from the integer System.Parameters.Size_Type to ease the
creation of objects of type SS_Stack by the binder and imposes a maximum
secondary stack size of 2GB. In most cases, the user will not hit this limit as
they cannot specify task stack sizes of more than 2GB via the Storage_Size and
Secondary_Stack_Size pragmas. Additionally, most operating systems limit the
primary stack size to less than 2GB, with defaults under 10MB. Linux is the
rare exception where the user can unbound the primary stack.
Executing the following:
gnatmake -q overflow
./overflow
must yield:

This patch modifies routine Find_Enclosing_Scope which obtains the scope of an
arbitrary node to return the unique defining entity of an enclosing body. This
automatically takes care of the following corner cases:
* The body is a subprogram body which does not complete a previous
declaration. In this case the proper scope is the entity of the
body.
* The body is an entry body. Due to a limitation in the AST, the
entry body does not store its correcponsing spec, but utilizes a
roundabout way of obtaining it. Regardless of the limitation, the
proper scope is the entity of the entry declaration.
The issue was discovered during the development of the GNATprove tool and
is not visible to end users. No simple test is available because this would
require a debug session.

This patch fixes the problem of aspect/pragma Secondary_Stack_Size expressions
with non-literals evaluating as zero in static secondary stacks allocations.
The aspect Secondary_Stack_Size is now converted to a pragma instead of an
attribute as the attribute does not have visibility on the discriminant.
Additionally, the discriminant of the corresponding record type is now
referenced if the pragma expression contains a discriminant.
No simple test available as the problem only impacts programs when
System.Parameters.Sec_Stack_Dynamic = False
2018-01-11 Patrick Bernardi <bernardi@adacore.com>
gcc/ada/
* exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
Secondary_Stack_Size handling as a pragma is now generated for the
corresponding aspect instead of an attribute. Pragma expression is
relocated instead of evaluated. Discriminant of the corresponding
record type is referenced rather than the type discriminant.
(Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
Secondary_Stack_Size rep item checks to only look for the pragma rep.
* sem_ch13.adb (Analyze_One_Aspect): Transform
Aspect_Secondary_Stack_Size into a pragma instead of an attribute
because the attribute does not have visibility on a task type's
discriminants when the type's definition is expanded.
(Analyze_Attribute_Definition_Clause): Remove handling of
Attribute_Secondary_Stack_Size.
* snames.adb-tmpl, snames.ads-tmpl: Remove
Attribute_Secondary_Stack_Size, no longer used.

This patch modifies the processing of controlled transient objects within case
expressions represented by an Expression_With_Actions node. The inspection of
an individual action must continue in case it denotes a complex expression,
such as a case statement, which in turn may contain additional transients.

This patch corrects the minor decoration performed on invariant procedures in
case the procedure is not inserted into the tree and analyzed. The decoration
now constructs a proper first/next/last entity chain containing the single
formal parameter which represents the object of the related type. The chain
then ensures that any other entities generated by the [pre]analysis of the
invariant expression will be properly added to the chain.
The issue was discovered during the development of the GNATprove tool and
is not visible to end users. No simple test is available because this would
require a debug session.
