libstdc++: Remove implicit type conversions in std::complex
...
The current implementation of `complex<_Tp>` assumes that int
`int` is implicitly convertible to `_Tp`, e.g., when using
`complex<_Tp>(1)`.
This patch transforms the implicit conversions into explicit type casts.
As a result, `std::complex` is now able to support more types. One
example is the type `Eigen::Half` from
https://eigen.tuxfamily.org/dox-devel/Half_8h_source.html which does not
implement implicit type conversions.
libstdc++-v3/ChangeLog:
* include/std/complex (polar, __complex_sqrt, pow)
(__complex_pow_unsigned): Use explicit conversions from int to
the complex value_type.

libstdc++: Deprecate non-standard std::fabs(const complex<T>&) [PR120235]
...
There was an overload of fabs for std::complex in TR1 and in some C++0x
drafts, but it was removed from the working draft by LWG 595.
Since we've been providing it for decades we should deprecate it before
removing it.

libstdc++: implement tuple protocol for std::complex (P2819R2)
...
This commit implements P2819R2 for C++26, making std::complex
destructurable and tuple-like (see [complex.tuple]).
std::get needs to get forward declared in stl_pair.h (following the
existing precedent for the implementation of P2165R4, cf.
r14-8710-g65b4cba9d6a9ff), and implemented in <complex>.
Also, std::get(complex<T>) needs to return *references* to the real and
imaginary parts of a std::complex object, honoring the value category
and constness of the argument. In principle a straightforward task, it
gets a bit convoluted by the fact that:
1) std::complex does not have existing getters that one can use for this
(real() and imag() return values, not references);
2) there are specializations for language/extended floating-point types,
which requires some duplication -- need to amend the primary and all
the specializations;
3) these specializations use a `__complex__ T`, but the primary template
uses two non-static data members, making generic code harder to write.
The implementation choice used here is to add the overloads of std::get
for complex as declared in [complex.tuple]. In turn they dispatch to a
newly added getter that extracts references to the real/imaginary parts
of a complex<T>. This getter is private API, and the implementation
depends on whether it's the primary (bind the data member) or a
specialization (use the GCC language extensions for __complex__).
To avoid duplication and minimize template instantiations, the getter
uses C++23's deducing this (this avoids const overloads). The value
category is dealt with by the std::get overloads.
Add a test that covers the aspects of the tuple protocol, as well as the
tuple-like interface. While at it, add a test for the existing
tuple-like feature-testing macro.

libstdc++: #ifdef out #pragma GCC system_header
...
In r15-3714-gd3a7302ec5985a I added -Wsystem-headers to the libstdc++ build
flags to help catch problems in the library. This patch takes a different
approach, of disabling the #pragma system_header unless _GLIBCXX_SYSHDR is
defined. As a result, the testsuites will treat them as non-system-headers
to get better warning coverage during regression testing of both gcc and
libstdc++, not just when building the library.
My rationale for the #ifdef instead of just removing the #pragma is the
three G++ tests that want to test libstdc++ system header behavior, so we
need a way to select it.
This doesn't affect installed libraries, as they get their
system-header status from the lookup path. But testsuite_flags
--build-includes gives -I directives rather than -isystem.
This patch doesn't change the headers in config/ because I'm not compiling
with most of them, so won't see any warnings that need fixing. Adjusting
them could happen later, or we can not bother.

libstdc++: add #pragma diagnostic
...
The use of #pragma GCC system_header in libstdc++ has led to bugs going
undetected for a while due to the silencing of compiler warnings that would
have revealed them promptly, and also interferes with warnings about
problematic template instantiations induced by user code.
But removing it, or even compiling with -Wsystem-header, is also problematic
due to warnings about deliberate uses of extensions.
So this patch adds #pragma GCC diagnostic as needed to suppress these
warnings.
The change to acinclude.m4 changes -Wabi to warn only in comparison to ABI
19, to avoid lots of warnings that we now mangle concept requirements, which
are in any case still experimental. I checked for any other changes against
ABI v15, and found only the <format> lambda mangling, which we can ignore.
This also enables -Wsystem-headers while building the library, so we see any
warnings not silenced by these #pragmas.

[libstdc++] add _GLIBCXX_CLANG to workaround predefined __clang__
...
A proprietary embedded operating system that uses clang as its primary
compiler ships headers that require __clang__ to be defined. Defining
that macro causes libstdc++ to adopt workarounds that work for clang
but that break for GCC.
So, introduce a _GLIBCXX_CLANG macro, and a convention to test for it
rather than for __clang__, so that a GCC variant that adds -D__clang__
to satisfy system headers can also -D_GLIBCXX_CLANG=0 to avoid
workarounds that are not meant for GCC.
I've left fast_float and ryu files alone, their tests for __clang__
don't seem to be harmful for GCC, they don't include bits/c++config,
and patching such third-party files would just make trouble for
updating them without visible benefit. pstl_config.h, though also
imported, required adjustment.

libstdc++: Stop using _GLIBCXX_USE_C99_MATH_TR1 in <cmath>
...
Similar to the three commits r14-908, r14-909 and r14-910, the
_GLIBCXX_USE_C99_MATH_TR1 macro is misleading when it is also used for
<cmath>, not only for <tr1/cmath> headers. It is also wrong, because the
configure checks for TR1 use -std=c++98 and a target might define the
C99 features for C++11 but not for C++98.
Add separate configure checks for the <math.h> functions using
-std=c++11 for the checks. Use the new macro defined by those checks in
the C++11-specific parts of <cmath>, and in <complex>, <random> etc.
The check that defines _GLIBCXX_NO_C99_ROUNDING_FUNCS is only needed for
the C++11 <cmath> checks, so remove that from GLIBCXX_CHECK_C99_TR1 and
only do it for GLIBCXX_ENABLE_C99.
libstdc++-v3/ChangeLog:
* acinclude.m4 (GLIBCXX_ENABLE_C99): Add checks for C99 math
functions and define _GLIBCXX_USE_C99_MATH_FUNCS. Move checks
for C99 rounding functions to here.
(GLIBCXX_CHECK_C99_TR1): Remove checks for C99 rounding
functions from here.

libstdc++: Stop using _GLIBCXX_USE_C99_COMPLEX_TR1 in <complex>
...
The _GLIBCXX_USE_C99_COMPLEX_TR1 macro (and the comments about it in
acinclude.m4 and config.h) are misleading when it is also used for
<complex>, not only <tr1/complex>. It is also wrong, because the
configure checks for TR1 use -std=c++98 and a target might define cacos
etc. for C++11 but not for C++98.
Add a separate configure check for the inverse trigonometric functions
that are covered by _GLIBCXX_USE_C99_COMPLEX_TR1, but using -std=c++11
for the checks. Use the result of that separate check in <complex>.
libstdc++-v3/ChangeLog:

libstdc++: Adjust <format> for Clang compatibility [PR107712]
...
Clang doesn't define __builtin_toupper, so use std::toupper.
Also add some (not actually required since C++20) typename keywords to
help Clang versions up to and including 15.
libstdc++-v3/ChangeLog:
PR libstdc++/107712
* include/std/format (__format::__formatter_int::format): Use
std::toupper when __builtin_toupper isn't available.
(basic_format_arg::handle): Add 'typename'.
* include/std/complex (complex<T>): Add 'typename'.

libstdc++: Fix up <complex> for extended floating point types [PR107649]
...
As filed by Jonathan in the PR, I've screwed up the requires syntax
in the extended floating point specialization:
- requires(__complex_type<_Tp>::type)
+ requires requires { typename __complex_type<_Tp>::type; }
and doing this change resulted in lots of errors because __complex_whatever
overfloads from extended floating point types were declared after the
templates which used them.
The following patch fixes that.
Bootstrapped/regtested on x86_64-linux and i686-linux, additionally
I've tested that with _GLIBCXX_HAVE_FLOAT128_MATH not being defined
while __STDCPP_FLOAT128_T__ defined one can still use
std::complex<std::float128_t> for basic arithmetic etc., just one can't
expect std::sin etc. to work in that case (because we don't have any
implementation).

libstdc++-v3: <complex> support for extended floating point types
...
The following patch adds <complex> support for extended floating point
types.
C++23 removes the float/double/long double specializations from the spec
and instead adds explicit(bool) specifier on the converting constructor.
The patch uses that for converting constructor of the base template as well
as the float/double/long double specializations's converting constructors
(e.g. so that it handles convertion construction also from complex of extended
floating point types). Copy ctor was already defaulted as the spec now
requires.
The patch also adds partial specialization for the _Float{16,32,64,128}
and __gnu_cxx::__bfloat16_t types because the base template doesn't use
__complex__ but a pair of floating point values.
The g++.dg/cpp23/ testcase verifies explicit(bool) works correctly.

libstdc++: Ensure all feature test macros have type long [PR87193]

This defines all the __cpp_lib_xxx macros as type long, as required by
the standard. We had an inconsistent mix of int and long, sometimes even
for the same macro name.
The __cpp_lib_experimental_xxx macros are left as type int, because
that's what it says in the relevant TS specs.

The current generic implementation of __complex_proj used when cproj is
not available calculates the wrong projection, giving a different result
than given by C99's cproj.
When C99 cproj is not available but isinf and copysign are, use those to
give correct results for float, double and long double. Otherwise, and
for other specializations of std::complex, just use a generic version
that returns its argument, and so doesn't support infinities.
