[arm] PR target/85658 Fix operator precedence errors in parsecpu.awk
There are a number of places in parsecpu.awk where I've managed to get
the operator precedence between ! and 'in' incorrect (! binds more
tightly). In most cases this just makes a consistency test
ineffective, but in a few cases it means we fail to correctly diagnose
errors by the user (for example, when passing an invalid cpu or
architecture name to configure. This patch fixes all the cases I
could find, based on searching for all uses of the two operators in
the same expression. The tweak to the API of check_fpu is to bring it
into line with the other check functions - it now returns the result
rather than printing it directly. The caller now does the printing,
in the same way that the chkarch and chkcpu commands do.

[AArch64] Predicated SVE comparison folds
This patch adds SVE patterns that combine a PTRUE-predicated
comparison with a separate AND. The main benefit is for
optimising ANDs with the loop predicate, as in the testcase.
However, one of the potential drawbacks is that it triggers
even for cases in which two naturally-parallel comparisons
are ANDed together. Whether that's a win or a less will
depend on the schedule, but it has the potential to be a win
more often than a loss.
The combine patterns are undeniably ugly. One way of getting
around them would be to allow 1->1 "splits" when combining
2 instructions, as well as 1->2 splits when combining more
than 2 instructions (although that wouldn't really be a split).
Another would be to have a way of defining target-specific
rtx simplifications. branches/ARM/sve-branch has a prototype
implementation of that, but it would need some clean-up before being
ready to submit. It would also be good to make it closer to the
match.pd style.
Until then, I think what the combine patterns are doing is the
"correct" implementation given the current infrastructure.

[AArch64] Use UNSPEC_MERGE_PTRUE for comparisons
This patch rewrites the SVE comparison handling so that it uses
UNSPEC_MERGE_PTRUE for comparisons that are known to be predicated
on a PTRUE, for consistency with other patterns. Specific unspecs
are then only needed for truly predicated floating-point comparisons,
such as those used in the expansion of UNEQ for flag_trapping_math.
The patch also makes sure that the comparison expanders attach
a REG_EQUAL note to instructions that use UNSPEC_MERGE_PTRUE,
so passes can use that as an alternative to the unspec pattern.
(This happens automatically for optabs. The problem was that
this code emits instruction patterns directly.)
No specific benefit on its own, but it lays the groundwork for
the next patch.

Introduce prefetch-dynamic-strides option.
The following patch adds an option to control software prefetching of memory
references with non-constant/unknown strides.
Currently we prefetch these references if the pass thinks there is benefit to
doing so. But, since this is all based on heuristics, it's not always the case
that we end up with better performance.
For Falkor there is also the problem of conflicts with the hardware prefetcher,
so we need to be more conservative in terms of what we issue software prefetch
hints for.
This also aligns GCC with what LLVM does for Falkor.
Similarly to the previous patch, the defaults guarantee no change in behavior
for other targets and architectures.

Introduce prefetch-minimum stride option
This patch adds a new option to control the minimum stride, for a memory
reference, after which the loop prefetch pass may issue software prefetch
hints for. There are two motivations:
* Make the pass less aggressive, only issuing prefetch hints for bigger strides
that are more likely to benefit from prefetching. I've noticed a case in cpu2017
where we were issuing thousands of hints, for example.
* For processors that have a hardware prefetcher, like Falkor, it allows the
loop prefetch pass to defer prefetching of smaller (less than the threshold)
strides to the hardware prefetcher instead. This prevents conflicts between
the software prefetcher and the hardware prefetcher.
I've noticed considerable reduction in the number of prefetch hints and
slightly positive performance numbers. This aligns GCC and LLVM in terms of
prefetch behavior for Falkor.
The default settings should guarantee no changes for existing targets. Those
are free to tweak the settings as necessary.

[BRIGFE] phsa-specific optimizations
Add flag -fassume-phsa that is on by default. If -fno-assume-phsa
is given, these optimizations are disabled.
With this flag, gccbrig can generate GENERIC that assumes we are
targeting a phsa-runtime based implementation, which allows us
to expose the work-item context accesses to retrieve WI IDs etc.
which helps optimizers.
First optimization that takes advantage of this is to get rid of
the setworkitemid calls whenever we have non-inlined calls that
use IDs internally.
Other optimizations added in this commit:
- expand absoluteid to similar level of simplicity as workitemid.
At the moment absoluteid is the best indexing ID to end up with
WG vectorization.
- propagate ID variables closer to their uses. This is mainly
to avoid known useless casts, which confuse at least scalar
evolution analysis.
- use signed long long for storing IDs. Unsigned integers have
defined wraparound semantics, which confuse at least scalar
evolution analysis, leading to unvectorizable WI loops.
- also refactor some BRIG function generation helpers to brig_function.
- no point in having the wi-loop as a for-loop. It's really
a do...while and SCEV can analyze it just fine still.
- add consts to ptrs etc. in BRIG builtin defs.
Improves optimization opportunities.
- add qualifiers to generated function parameters.
Const and restrict on the hidden local/private pointers,
the arg buffer and the context pointer help some optimizations.

[BRIGFE] Enable whole program optimizations
HSA assumes all program scope HSAIL symbols can be queried from

Getting some inlining happening in the finalized binary required:
* explicitly marking the 'prog' scope functions and the launcher
function "externally_visible" to avoid the inliner removing it
* also the host_def ptr is set to externally visible, otherwise
IPA assumes it's never set
* adding the 'inline' keyword to functions to enable inlining,
otherwise GCC defaults to replaceable functions (one can link
over the previous one) which cannot be inlined
* replacing all calls to declarations with calls to definitions to
enable the inliner to find the definition
* to fix missing hidden argument types in the generated functions.
These were ignored silently until GCC started to be able to
inline calls to such functions.
* do not gimplify before fixing the call targets. Otherwise the
calls get detached and the definitions are not found. The reason

libffi PowerPC64 ELFv1 fp arg fixes
The ELFv1 ABI says: "Single precision floating point values are mapped
to the second word in a single doubleword" and also "Floating point
registers f1 through f13 are used consecutively to pass up to 13
floating point values, one member aggregates passed by value
containing a floating point value, and to pass complex floating point
values".
libffi wasn't expecting float args in the second word, and wasn't
passing one member aggregates in fp registers. This patch fixes those
problems, making use of the existing ELFv2 homogeneous aggregate
support since a one element fp struct is a special case of an
homogeneous aggregate.
I've also set a flag when returning pointers that might be used one
day. This is just a tidy since the ppc64 assembly support code
currently doesn't test FLAG_RETURNS_64BITS for integer types..

PR libstdc++/84535 constrain std::thread constructor
The standard requires that the std::thread constructor is constrained so
it can't be called with a first argument of type std::thread. The
current implementation only meets that requirement if the constructor is
called with one argument, by using deleted overloads. This uses an
enable_if constraint to enforce the requirement for any number of
arguments.
Also add a static assertion to give a more readable error for invalid
arguments that cannot be invoked. Also simplify _Invoker to reduce the
error cascade for ill-formed instantiations with non-invocable
arguments.

[tree-complex.c] PR tree-optimization/70291: Inline floating-point complex multiplication more aggressively
We can improve the performance of complex floating-point multiplications by inlining the expansion a bit more aggressively.
We can inline complex x = a * b as:
x = (ar*br - ai*bi) + i(ar*bi + br*ai);
if (isunordered (__real__ x, __imag__ x))
x = __muldc3 (a, b); //Or __mulsc3 for single-precision
That way the common case where no NaNs are produced we can avoid the libgcc call and fall back to the
NaN handling stuff in libgcc if either components of the expansion are NaN.
The implementation is done in expand_complex_multiplication in tree-complex.c and the above expansion
will be done when optimising for -O1 and greater and when not optimising for size.
At -O0 and -Os the single call to libgcc will be emitted.
For the code:
__complex double
foo (__complex double a, __complex double b)
{
return a * b;
}
We will now emit at -O2 for aarch64:
foo:
fmul d16, d1, d3
fmul d6, d1, d2
fnmsub d5, d0, d2, d16
fmadd d4, d0, d3, d6
fcmp d5, d4
bvs .L8
fmov d1, d4
fmov d0, d5
ret
.L8:
stp x29, x30, [sp, -16]!
mov x29, sp
bl __muldc3
ldp x29, x30, [sp], 16
ret
Instead of just a branch to __muldc3.
