testsuite: Fix up pr107541.c test
The test fails when long is 32-bit rather than 64-bit (say x86_64 with
RUNTESTFLAGS='--target_board=unix\{-m32,-m64\} tree-ssa.exp=pr107541.c'
).
I've tweaked it to use long long so it passes even on the 32-bit
targets, and added an early out for weirdo targets because I think
the test assumes the usual 1/2/4/8 bytes sizes for char/short/int/long long.

PR tree-optimization/107541
* gcc.dg/tree-ssa/pr107541.c (c): Use long long type rather than long.
(main): Punt if sizeof short isn't 2, or int 4, or long long 8.

`basic_filebuf::xsputn` would bypass the buffer when passed a chunk of

This can have a significant performance impact if the overhead of a
`write` syscall is non-negligible, e.g. on a slow disk, on network
filesystems, or simply during IO contention because instead of flushing
every `BUFSIZ` (by default), we can flush every 1024 char.
The impact is even greater with custom larger buffers, e.g. for network
filesystems, because the code could issue `write` for example 1000X more
often than necessary with respect to the buffer size.
It also introduces a significant discontinuity in performance when
writing chunks of size 1024 and above.
Instead, it makes sense to only bypass the buffer if the amount of data
to be written is larger than the buffer capacity.

[PR24021] Implement PLUS_EXPR range-op entry for floats.
This is the range-op entry for floating point PLUS_EXPR. It's the
most intricate range entry we have so far, because we need to keep
track of rounding and target FP formats. This will be the last FP
entry I commit, mostly to avoid disturbing the tree any further, and
also because what we have so far is enough for a solid VRP.
So far we track NANs and signs correctly. We also handle relationals
(symbolics and numeric), both ordered and unordered, ABS_EXPR and
NEGATE_EXPR which are used to fold __builtin_isinf, and __builtin_sign
(__builtin_copysign is coming up). All in all, I think this provide
more than enough for basic VRP on floats, as well as provide a basis
to flesh out the rest if there's interest.
My goal with this entry is to provide a template for additional binary
operators, as they tend to follow a similar pattern: handle NANs, do
the arithmetic while keeping track of rounding, and adjust for NAN. I
may abstract the general parts as we do for irange's fold_range and

Use bit-CCP in range-ops.
After Jakub and Richi's suggestion of using the same representation
for tracking known bits as we do in CCP, I took a peek at the code and
realized there's a plethora of bit-tracking code there that we could
be sharing with range-ops. For example, the multiplication
optimizations are way better than what I had cobbled together. For
that matter, our maybe nonzero tracking as a whole has a lot of room
for improvement. Being the lazy ass that I am, I think we should just
use one code base (CCP's).
This patch provides a thin wrapper for converting the irange maybe
nonzero bits to what CCP requires, and uses that to call into
bit_value_binop(). I have so far converted the MULT_EXPR range-op
entry to use it, as the DIV_EXPR entry we have gets a case CCP doesn't
get so I'd like to contribute the enhancement to CCP before converting
over.
I'd like to use this approach with the dozen or so tree_code's that
are handled in CCP, thus saving us from having to implement any of
them :).
Early next season I'd like to change irange's internal representation
to a pair of value / mask, and start tracking all known bits. This
ties in nicely with our plan for tracking known set bits.
Perhaps if the stars align, we could merge the bit twiddling in CCP
into range-ops and have a central repository for it. That is, once we
make the switch to wide-ints, and assuming there are no performance
issues. Note that range-ops is our lowest level abstraction.
i.e. it's just the math, there's no GORI or ranger, or even the
concept of a symbolic or SSA.

The following patch does that. For many of the builtins (like acos, or

some (cosh, sinh, exp{,m1,2}) it is different for each format,
so I had to compute those ranges.
Note, seems the existing ranges were in some cases (e.g. for exp2)
the smallest in absolute value which results infinite result, in others
the largest which still results in finite result (but consistently so
for the IEEE single vs. double). I've followed that for IEEE half and
quad cases too, just am not sure why it was like that. I think
get_domain with true, false is open interval rather than closed
and the comments indicate that too, conservatively that is certainly
correct.

frange can prove we are in the domain range.

i386: Improve vector [GL]E{,U} comparison against vector constants [PR107546]
For integer vector comparisons without XOP before AVX512{F,VL} we are
constrained by only GT and EQ being supported in HW.
For GTU we play tricks to implement it using GT or unsigned saturating
subtraction, for LT/LTU we swap the operands and thus turn it into
GT/GTU. For LE/LEU we handle it by using GT/GTU and negating the
result and for GE/GEU by using GT/GTU on swapped operands and negating
the result.
If the second operand is a CONST_VECTOR, we can usually do better though,
we can avoid the negation. For LE/LEU cst by doing LT/LTU cst+1 (and
then cst+1 GT/GTU x) and for GE/GEU cst by doing GT/GTU cst-1, provided
there is no wrap-around on those cst+1 or cst-1.
GIMPLE canonicalizes x < cst to x <= cst-1 etc. (the rule is smaller
absolute value on constant), but only for scalars or uniform vectors,
so in some cases this undoes that canonicalization in order to avoid
the extra negation, but it handles also non-uniform constants.

c++: implement P2468R2, the equality operator you are looking for
This paper is resolving the problem of well-formed C++17 code becoming
ambiguous in C++20 due to asymmetrical operator== being compared with itself
in reverse. I had previously implemented a tiebreaker such that if the two
candidates were functions with the same parameter types, we would prefer the
non-reversed candidate. But the committee went with a different approach:
if there's an operator!= with the same parameter types as the operator==,
don't consider the reversed form of the ==.
So this patch implements that, and changes my old tiebreaker to give a
pedwarn if it is used. I also noticed that we were giving duplicate errors
for some testcases, and fixed the tourney logic to avoid that.
As a result, a lot of tests of the form
struct A { bool operator==(const A&); };
need to be fixed to add a const function-cv-qualifier, e.g.
struct A { bool operator==(const A&) const; };
The committee thought such code ought to be fixed, so breaking it was fine.
18_support/comparisons/algorithms/fallback.cc also breaks with this patch,
because of the similarly asymmetrical
bool operator==(const S&, S&) { return true; }
As a result, some of the asserts need to be reversed.
The H test in spaceship-eq15.C is specified in the standard to be
well-formed because the op!= in the inline namespace is not found by the
search, but that seems wrong to me. I've implemented that behavior, but
disabled it for now; if we decide that is the way we want to go, we can just
remove the "0 &&" in add_candidates to enable it.

libstdc++: Implement ranges::cartesian_product_view from P2374R4
This also implements the proposed resolutions of the tentatively ready
LWG issues 3760, 3761 and 3801 for cartesian_product_view.
I'm not sure how/if we should implement the recommended practice of:
iterator::difference_type should be the smallest signed-integer-like
type that is sufficiently wide to store the product of the maximum
sizes of all underlying ranges if such a type exists
because for e.g.
extern std::vector<int> x, y;
auto v = views::cartesian_product(x, y);
IIUC it'd mean difference_type should be __int128 (on 64-bit systems),
which seems quite wasteful: in practice the size of any cartesian product
probably won't exceed the precision of say ptrdiff_t, and using anything
larger will just incur unnecessary space/time overhead. It's also
probably not worth the complexity to use less precision than ptrdiff_t
(when possible) either. So this patch defines difference_type as
which should mean it's least as large as the difference_type of each
underlying range, and at least as large as ptrdiff_t. This patch also
adds assertions to catch any overflow that occurs due to this choice of
difference_type.

libstdc++: Add _Float128 to_chars/from_chars support for x86, ia64 and ppc64le with glibc
The following patch adds std::{to,from}_chars support for std::float128_t
on glibc 2.26+ for {i?86,x86_64,ia64,powerpc64le}-linux.
When long double is already IEEE quad, previous changes already handle
it by using long double overloads in _Float128 overloads.
The powerpc64le case (with explicit or implicit -mabi=ibmlongdouble)
is handled by using the __float128/__ieee128 entrypoints which are
already in the library and used for -mabi=ieeelongdouble.
For i?86, x86_64 and ia64 this patch adds new library entrypoints,
mostly by enabling the code that was already there for powerpc64le-linux.
Those use __float128 or __ieee128, the patch uses _Float128 for the
exported overloads and internally as template parameter. While
powerpc64le-linux uses __sprintfieee128 and __strtoieee128,
for _Float128 the patch uses the glibc 2.26 strfromf128 and strtof128
APIs. So that one can build gcc against older glibc and then compile
user programs on newer glibc, the patch uses weak references unless
gcc is compiled against glibc 2.26+. strfromf128 unfortunately can't
handle %.0Lf and %.*Le, %.*Lf, %.*Lg format strings sprintf/__sprintfieee128
use, we need to remove the L from those and replace * with actually
directly printing the precision into the format string (i.e. it can
handle %.0f and %.27f (floating point type is implied from the function
name)).
Unlike the std::{,b}float16_t support, this one actually exports APIs
with std::float128_t aka _Float128 in the mangled name, because no
standard format is superset of it. On the other side, e.g. on i?86/x86_64
it doesn't have restrictions like for _Float16/__bf16 which ISAs need
to be enabled in order to use it.
The denorm_min case in the testcase is temporarily commented out because
of the ERANGE subnormal issue Patrick posted patch for.
