The initial signal handling code introduced for aarch64-android
overlooked details of the tasking runtime, not in the initial testing
perimeter.
Specifically, a reference to __gnat_sigtramp from __gnat_error_handler,
initially introduced for the arm port, was prevented if !arm on the
grounds that other ports would rely on kernel CFI. aarch64-android
does provide kernel CFI and __gnat_sigtramp was not provided for this
configuration.
But there is a similar reference from s-intman__android, which kicks in
as soon as the tasking runtime gets activated, triggering link failures.
Testing for more precise target specific parameters from Ada
code is inconvenient and replicating the logic is not attractive in
any case, so this change addresses the problem in the following
fashion:
- Always provide a __gnat_sigtramp entry point, common to the
tasking and non-tasking signal handling code for all the Android
configurations,
- There (C code), from target definition macros, select a path
that either routes directly to the actual signal handler or goes
through the intermediate layer providing hand crafted CFI
information which allows unwinding up to the interrupted code.
- Similarily to what was done for VxWorks, move the arm specific
definitions to a separate header file to make the general structure
of the common C code easier to grasp,
- Adjust the comments in the common sigtramp.h header to
account for such an organisation possibility.
gcc/ada/ChangeLog:
* sigtramp-armdroid.c: Refactor into ...
* sigtramp-android.c, sigtramp-android-asm.h: New files.
* Makefile.rtl (arm/aarch64-android section): Add
sigtramp-android.o to EXTRA_LIBGNAT_OBJS unconditionally. Add
sigtramp.h and sigtramp-android-asm.h to EXTRA_LIBGNAT_SRCS.
* init.c (android section, __gnat_error_handler): Defer to
__gnat_sigramp unconditionally again.
* sigtramp.h: Adjust comments to allow neutral signal handling
relays, merely forwarding to the underlying handler without any
intermediate CFI magic.

Building an aarch64-android compiler with the current sources
initially intended for arm-android expectedly trips on problems.
This change is meant to address:
```
.../gcc/ada/rts % ../../gnat1 -quiet ... a-stbufi.adb -I.
s-osinte.ads:591:07: error: component "sa_flags" overlaps "sa_mask" at line 590
```
s-linux__android.ads makes hardcoded assumptions on the size
of sigset_t, based on observations performed in the course of the
arm port.
Then sysem headers show sa_flags placed VERY differently between
the 32 and the 64 bits variants.
See android-sysroot/usr/include/bits/signal_types.h

This set of changes is aimed at streamlining the code generated for the
elaboration of local tagged types. The dispatch tables and other related
data structures are built dynamically on the stack for them and a few of
the patterns used for this turn out to be problematic for the optimizer:
1. the array of primitives in the dispatch table is default-initialized to
null values by calling the initialization routine of an unconstrained
array type, and then immediately assigned an aggregate made up of the
same null values.
2. the external tag is initialized by means of a dynamic concatenation
involving the secondary stack, but all the elements have a fixed size.
3. the _size primitive is saved in the TSD by means of the dereference of
the address of the TSD that was previously saved in the dispatch table.

This replaces spinlocks with fully-fledged locks in finalization collections
because the former are deemed problematic with tasks that can be preempted.
Because of the requirement to avoid dragging the tasking runtime when it is
not necessary, the implementation goes through the usual soft links, with an
additional hurdle that space must be reserved for the lock in any case since
it is part of the ABI. This entails the introduction of the System.OS_Locks
unit in the non-tasking runtime and the modification of the tasking runtime
to also use this unit.
This in turn requires a small adjustment: because of the presence of pre-
and post-conditions in Interfaces.C and of the limitations of the RTSfind
mechanism, the System.Finalization_Primitives unit must be preloaded, as
what is done for the Ada.Strings.Text_Buffers unit.
This effectively reverts the implementation to using the global task lock on
bare board platforms.

This change replaces finalization masters with finalization collections in
most cases, that is to say, when they implement a list of objects created
by allocators of a given access type; indeed the moniker is overloaded in
the front-end, e.g. Sem_Util.Is_Master determines if a node "constitutes
a finalization master" but is not affected by the change.
This is mostly a renaming at this stage, toward something more in keeping
with the terminology used in the RM 7.6.1 clause and no functional changes:
although it gets rid of the rest of the System.Finalization_Masters unit,
the functionalities are reimplemented in the System.Finalization_Primitives
unit in terms of collections with only minor adjustments.

The VxWorks 7 API to use hardware interrupts is the VxBus subsystem.
GNAT API still provides bindings for the deprecated (VxWorks 6) routines.
A direct consequence of this change is that Attach_Handler cannot be
used anymore (the VxBus subsystem should be used instead).
This patch removes all the functions that are not supported by VxWorks 7
anymore.
To warn for the usage of Attach_Handler, it adds the 'Obsolescent'
pragma to to this routine so the comiler will advise the user if this
function is called directly or through a pragma.

This set of changes is a partial reimplemention of the support for Ada
finalization in the GNAT compiler and run-time library, based on the
redesign done by Hristian Kirtchev in February 2022. It only affects
the scope-based finalization of objects and does not touch the support
for finalization of dynamically allocated objects.
It also does not modify the internal architecture of this support in the
front-end but only changes its output, i.e. the expanded code. In other
words, the code-based dispatching scheme in finalizers and the hook-based
approach for transient objects are replaced by finalization scope masters
and master nodes, which maintain a list of objects needing finalization,
but the expansion of the code that builds these masters is still performed
mainly during a dedicated post-processing phase.

Spec units for verification of the GNAT standard library with GNATprove
must be listed as part of the libgnat package, as otherwise libadalang

Before this patch, the only formal doubly linked lists were bounded and
definite. This means that it is necessary to provide their maximum
length or capacity at instantiation and that they can only be used with
definite element types.
The formal lists added by this patch are unbounded and indefinite.
Their length grows dynamically until Count_Type'Last. This makes them
easier to use but requires the use of dynamic allocation and controlled
types.
gcc/ada/
* libgnat/a-cfidll.adb, libgnat/a-cfidll.ads: Implementation
files of the formal unbounded indefinite list.
* Makefile.rtl, impunit.adb: Take into account the add of the
new files.

Only smp runtimes are built for vxworks7*, even though the -smp suffix
is removed during install. Therefore, in general, the build macros for
the non-smp runtimes are superfluous except on the legacy ppc-vxworks6
target where both the smp and non-smp runtime are built. Lastly, an
error message is added if a runtime build is commanded that doesn't
exist, rather then letting the build mysteriously fail.
gcc/ada/
* Makefile.rtl [arm,aarch64 vxworks7]: Remove rtp and kernel
build macros and set an error variable if needed.

Changes in GNATprove (translation to Why3 and provers) result in proofs
being much less automatic, and requiring ghost code to detail
intermediate steps. In some cases, it is better to use the new By
mechanism to prove assertions in steps, as this avoids polluting the
proof context for other proofs. For that reason, add units s-spark.ads
and s-spcuop.ads/b to the runtime sources.

* Makefile.rtl: Add new units.
* libgnat/s-aridou.adb (Scaled_Divide): Add ghost code for provers.

This eliminates the use of the secondary stack to return composite types
with controlled components from functions, by exposing the return slot of
these functions through the support interface of memory pools, much like
for the secondary stack itself. This is piggybacked on the support of a
specific intrinsic function by the code generator, and can be disabled if
this support is not available, as well with the -gnatd_r debug switch.
The change also streamlines a bit the implementation by consistently using
the Needs_Finalization predicate, or its derivatives, in various places.

This adds a package renaming unit to the GNAT hierarchy so as to expose
the underlying implementation of floating-point mathematical functions,
thus also making it possible to use their vector implementation, if any.
The change also contains a small improvement to the Hide_Public_Entities
mechanism in Sem_Ch7 that makes it possible to clear the Is_Public flag
within instances of generic packages that do not have a body.

This is an incremental change towards supporting shared libraries
for VxWorks on aarch64.
The aarch64-vx7r2 compiler supports compilation with -fpic/PIC. This
change adds aarch64 to the list of CPUs for which GNATLIB_SHARED maps to
gnatlib-shared-dual for vxworks7r2, so "make gnatlib-shared" actually
builds a shared lib.
While other adjustments will be needed to get the runtime tests to pass,
this one is a necessary step and doesn't impair the rest.
gcc/ada/
* Makefile.rtl: Add aarch64 to the list of CPUs for which
GNATLIB_SHARED maps to gnatlib-shared-dual for vxworks7r2.

Formal hashed sets and maps are now using a different type of hash table
that does not require controlled types. This is possible because formal
containers do not rely on tampering checks, as cursors do not hold a
pointer to a single matching container, but are logical indexes that can
be used with multiple containers.
For simplicity of the package organisation, and symmetry with other
versions of containers, add a formal version of hashed types in the
shared Ada.Containers.Hash_Tables unit. This unit should be specialized
to only include the formal version of hash tables for runtimes that
do not support controlled types (so that the dependency on
Ada.Containers.Helpers can be removed).
The new versions of units for generic keys and operations are modified
versions of the units for bounded containers, with all tampering checks
removed (they were no-op in formal containers). A declaration of
constant Checks is added at the start of the body, as these units cannot
use the version in Ada.Containers.Helpers.
gcc/ada/
* Makefile.rtl: Add new files.
* libgnat/a-cfhama.adb: Use formal version of hash tables.
* libgnat/a-cfhama.ads: Same.

version of Generic_Bounded_Operations.
* libgnat/a-chtgfo.ads: Same.
* libgnat/a-cohata.ads (Generic_Formal_Hash_Table_Types): Third
version of the type for hash tables, equivalent to the bounded
version without tampering checks.
