The EOR support includes the important special case of an inverted

The real motivating case for this is the ACLE svdupq function,

individual scalar booleans. It's not easy to test properly

[AArch64] Rework SVE integer comparisons
The remaining uses of UNSPEC_MERGE_PTRUE were in integer comparison
patterns. These aren't actually merging operations but zeroing ones,
although there's no practical difference when the predicate is a PTRUE.
All comparisons produced by expand are predicated on a PTRUE,
although we try to pattern-match a compare-and-AND as a predicated
comparison during combine.
Like previous patches, this one rearranges things in a way that works
better with the ACLE, where the initial predicate might or might not
be a PTRUE. The new patterns use UNSPEC_PRED_Z to represent zeroing
predication, with a aarch64_sve_ptrue_flag to record whether the
predicate is all-true (as for UNSPEC_PTEST).

[AArch64] Use "x" predication for SVE integer arithmetic patterns
The SVE patterns used an UNSPEC_MERGE_PTRUE unspec to attach a predicate
to an otherwise unpredicated integer arithmetic operation. As its name
suggests, this was designed to be a wrapper used for merging instructions
in which the predicate is known to be a PTRUE.
This unspec dates from the very early days of the port and nothing has
ever taken advantage of the PTRUE guarantee for arithmetic (as opposed
to comparisons). This patch replaces it with the less stringent
guarantee that:
(a) the values of inactive lanes don't matter and
(b) it is valid to make extra lanes active if there's a specific benefit
Doing this makes the patterns suitable for the ACLE _x functions, which
have the above semantics.

[AArch64] Rearrange SVE conversion patterns
The SVE int<->float conversion patterns need to handle various
combinations of modes, making sure that the predicate mode is based
on the widest element size. We did this using separate patterns for
conversions involving:
- HF (converting to/from [HSD]I, predicated based on the int operand)
- SF (converting to/from [SD]I, predicated based on the int operand)
- DF (converting to/from [SD]I, predicated based on the float operand)
This worked, and meant that there were no redundant patterns. However,
the ACLE needs various new predicated patterns too, and having three
versions of each one seemed excessive.
This patch instead splits the patterns into two groups rather than three.
For conversions to integers:
- truncating (predicated based on the source type, DF->SI only)
- non-truncating (predicated based on the destination type)
For conversions from integers:
- extending (predicated based on the destination type, SI->DF only)
- non-extending (predicated based on the source type)
This means that we still don't create pattern names for the invalid
combinations DF<->HI and SF<->HI. The downside is that we need to
use C conditions to exclude the SI<->DF case from the non-truncating/
non-extending patterns. We therefore have two pattern names for SI<->DF,
but genconditions ensures that the invalid one always has the value
CODE_FOR_nothing.

[AArch64] Add a "GP strictness" operand to SVE FP unspecs
This patch makes the SVE unary, binary and ternary FP unspecs
take a new "GP strictness" operand that indicates whether the
predicate has to be taken literally, or whether it is valid to
make extra lanes active (up to and including using a PTRUE).
This again is laying the groundwork for the ACLE patterns,
in which the value can depend on the FP command-line flags.
At the moment it's only needed for addition, subtraction and
multiplication, which have unpredicated forms that can only
be used when operating on all lanes is safe. But in future
it might be useful for optimising predicate usage.
The strict mode requires extra alternatives for addition,

between modes. This is also useful for the ACLE, where the single
predicate type svbool_t is always a VNx16BI.
Also, and again to encourage reuse, the patch makes us use a .B PTRUE
for all ptrue-predicated operations, rather than (for example) using
a .S PTRUE for 32-bit operations and a .D PTRUE for 64-bit operations.
The only current case in which a .H, .S or .D operation needs to be
predicated by a "strict" .H/.S/.D PTRUE is the PTEST in a conditional
branch, which an earlier patch fixed to use an appropriate VNx16BI

Use checking forms of DECL_FUNCTION_CODE (PR 91421)
We were shoe-horning all built-in enumerations (including frontend
and target-specific ones) into a field of type built_in_function. This
was accessed as either an lvalue or an rvalue using DECL_FUNCTION_CODE.
The obvious danger with this (as was noted by several ??? comments)
is that the ranges have nothing to do with each other, and targets can
easily have more built-in functions than generic code. But my patch to
make the field bigger was the straw that finally made the problem visible.
This patch therefore:
- replaces the field with a plain unsigned int
- turns DECL_FUNCTION_CODE into an rvalue-only accessor that checks
that the function really is BUILT_IN_NORMAL
- adds corresponding DECL_MD_FUNCTION_CODE and DECL_FE_FUNCTION_CODE
accessors for BUILT_IN_MD and BUILT_IN_FRONTEND respectively
- adds DECL_UNCHECKED_FUNCTION_CODE for places that need to access the
underlying field (should be low-level code only)
- adds new helpers for setting the built-in class and function code
- makes DECL_BUILT_IN_CLASS an rvalue-only accessor too, since all
assignments should go through the new helpers

Protect some checks of DECL_FUNCTION_CODE
This patch protects various uses of DECL_FUNCTION_CODE that didn't
obviously check for BUILT_IN_NORMAL first (either directly or in callers).
They could therefore trigger for functions that either aren't built-ins
or are a different kind of built-in.
Also, the patch removes a redundant GIMPLE_CALL check from
optimize_stdarg_builtin, since it gave the impression that the stmt
was less well checked than it actually is.

Optimise constant IFN_WHILE_ULTs
This patch is a combination of two changes that have to be
committed as a single unit:
(1) Try to fold IFN_WHILE_ULTs with constant arguments to a VECTOR_CST
(which is always possible for fixed-length vectors but is not
necessarily so for variable-length vectors)
(2) Make the SVE port recognise constants that map to PTRUE VLn,
which includes those generated by the new fold.
(2) can't be tested without (1) and (1) would be a significant
pessimisation without (2).
The target-specific parts also start moving towards doing predicate
manipulation in a canonical VNx16BImode form, using rtx_vector_builders.

[AArch64] Improve SVE constant moves
If there's no SVE instruction to load a given constant directly, this
patch instead tries to use an Advanced SIMD constant move and then
duplicates the constant to fill an SVE vector. The main use of this
is to support constants in which each byte is in { 0, 0xff }.
Also, the patch prefers a simple integer move followed by a duplicate
over a load from memory, like we already do for Advanced SIMD. This is
a useful option to have and would be easy to turn off via a tuning
parameter if necessary.
The patch also extends the handling of wide LD1Rs to big endian,
whereas previously we punted to a full LD1RQ.

[AArch64] Make aarch64_classify_vector_mode use a switch statement
aarch64_classify_vector_mode used properties of a mode to test whether
the mode was a single Advanced SIMD vector, a single SVE vector, or a
tuple of SVE vectors. That works well for current trunk and is simpler
than checking for modes by name.
However, for the ACLE and for planned autovec improvements, we also
need partial SVE vector modes that hold:
- half of the available 32-bit elements
- a half or quarter of the available 16-bit elements
- a half, quarter, or eighth of the available 8-bit elements
These should be packed in memory and unpacked in registers. E.g.
VNx2SI has half the number of elements of VNx4SI, and so is half the
size in memory. When stored in registers, each VNx2SI element occupies
the low 32 bits of a VNx2DI element, with the upper bits being undefined.
The upshot is that:
GET_MODE_SIZE (VNx4SImode) == 2 * GET_MODE_SIZE (VNx2SImode)
since GET_MODE_SIZE must always be the memory size. This in turn means
that for fixed-length SVE, some partial modes can have the same size as
Advanced SIMD modes. We then need to be specific about which mode we're
dealing with.
This patch prepares for that by switching based on the mode instead
of querying properties.
A later patch makes sure that Advanced SIMD modes always win over
partial SVE vector modes in normal queries.

[Ada] Fix spurious instantiation error on private record type
This change was initially aimed at fixing a spurious instantiation error
due to a disambiguation issue which happens when a generic unit with two
formal type parameters is instantiated on a single actual type that is
private.
The compiler internally sets the Is_Generic_Actual_Type flag on the
actual subtypes built for the instantiation in order to ease the
disambiguation, but it would fail to set it on the full view if the
subtypes are private. The change makes it so that the flag is properly
set and reset on the full view in this case.
But this uncovered an issue in Subtypes_Statically_Match, which was
relying on a stalled Is_Generic_Actual_Type flag set on a full view
outside of the instantiation to return a positive answer. This bypass
was meant to solve an issue arising with a private discriminated record
type whose completion is a discriminated record type itself derived from
a private discriminated record type, which is used as actual type in an
instantiation in another unit, and the instantiation is used in a child
unit of the original unit. In this case, the private and full views of
the generic actual type are swapped in the child unit, but there was a
mismatch between the chain of full and underlying full views of the
private discriminated record type and that of the generic actual type.
This secondary issue is solved by avoiding to skip the full view in the
preparation of the completion of the private subtype and by directly
constraining the underlying full view of the full view of the base type
instead of building an underlying full view from scratch.

[Ada] Add conformance check on actual subp. in instance of child unit
This patch properly diagnoses a conformance error between a formal
subprogram and the corresponding actual, when the instance is that of a
child unit that is instantiated as a compilation unit. The error is
normally suppressed on an instantiation nested within another generic,
given that analysis of the enclosing generic will have performed the
conformance check on the nested instance already. In the case of a
child unit, its instantiation requires an explicit check if it is a
compilation unit, because it has not been analyzed in the context of the
parent generic.
Compiling test.adb must yield:

[Ada] Do full name qualification of local exception names for LLVM
Exceptions declared within subprograms are associated with objects
allocated statically (at the global level), and it's helpful for the
LLVM compiler (and likely others, such as CCG) if the exception name is
fully qualified, to avoid link name clashes (gcc-based GNAT has always
"uniquified" these names). GNAT was using the simple name for local
exceptions (as for other local objects), but it now uses fully qualified
names for all exceptions.
When compiled with the command:
gcc -c -gnatG local_exception.adb | grep "local_exception__local_exc"
the following output is generated for the test further below:
local_exception__local_exc : static exception := (
local_exception__local_exc'unrestricted_access));
procedure Local_Exception is
Local_Exc : exception;
begin
null;

[Ada] Compiler may blow up on array aggregates whose size is very large
The compiler may crash when compiling array aggregates where the
computation of the size produces a very large number that overflows
(possibly producing a small result), such as with an aggregate of a type
that is an array of arrays, where each array range has close to
Integer'Last elements. That can lead to Aggr_Size_OK returning
incorrectly returning True, following on to allocating a very large
array in function Flatten that blows the stack. The size computation
was being performed using type Int, so this was changed to use universal
arithmetic.

[Ada] Avoid crash in GNATprove_Mode on allocator inside type
In the special mode for GNATprove, subtypes should be declared for
allocators when constraints are used. This was done previously but it
does not work inside spec expressions, as the declaration is not
inserted and analyzed in the AST in that case, leading to a later crash
on an incomplete entity. Thus, no declaration should be created in such
a case, letting GNATprove later reject such code due to the use of an
allocator in an interfering context.
