PR libstdc++/78420 Make std::less etc. yield total order for pointers
...
In order for std::less<T*> etc. to meet the total order requirements of
[comparisons] p2 we need to cast unrelated pointers to uintptr_t before
comparing them. Those casts aren't allowed in constant expressions, so
only cast when __builtin_constant_p says the result of the comparison is
not a compile-time constant (because the arguments are not constants, or
the result of the comparison is unspecified). When the result is
constant just compare the pointers directly without casting.
This ensures that the function can be called in constant expressions
with suitable arguments, but still yields a total order even for
otherwise unspecified pointer comparisons.
For std::less<void> etc. add new overloads for pointers, which use
std::less<common_type_t<T*,U*>> directly. Also change the generic
overloads to detect when the comparison would call a built-in relational
operator with pointer operands, and dispatch that case to the
corresponding specialization for void pointers.

Use non-throwing is_directory in filesystem::create_directory
...
The create_dir helper was calling the throwing form of
filesystem::is_directory instead of passing the error_code argument.
Since std::filesystem::create_directory(const path&, error_code&) is
noexcept, it would call std::terminate if an error occurred in
is_directory.
Passing the error_code also takes care of clearing it in the case where
is_directory returns true.

[aarch64][libstdc++] Use __ARM_BIG_ENDIAN instead of __AARCH64EB__ in opt_random.h
...
As has been spotted at https://gcc.gnu.org/ml/gcc-patches/2017-12/msg01289.html
we check the __AARCH64EB__ macro for aarch64 big-endian
detection in config/cpu/aarch64/opt/ext/opt_random.h.
That works just fine with GCC but the standardised ACLE[1] macro
for that purpose is __ARM_BIG_ENDIAN so there is a possibility
that non-GCC compilers that include this header are not aware
of this predefine.
So this patch changes the use of __AARCH64EB__ to
the more portable __ARM_BIG_ENDIAN.
Tested on aarch64-none-elf and aarch64_be-none-elf.
Preapproved by Jeff at https://gcc.gnu.org/ml/gcc-patches/2017-12/msg01326.html
* config/cpu/aarch64/opt/ext/opt_random.h (__VEXT): Check
__ARM_BIG_ENDIAN instead of __AARCH64EB__.

C++: improve location of static_assert errors
...
gcc/cp/ChangeLog:
* parser.c (cp_parser_unary_expression): Generate a location for
"noexcept".
(cp_parser_trait_expr): Generate and return a location_t,
converting the return type from tree to cp_expr.
(cp_parser_static_assert): Pass location of the condition to
finish_static_assert, rather than that of the "static_assert"
token, where available.
gcc/testsuite/ChangeLog:
* g++.dg/cpp1y/static_assert3.C: New test case.
libstdc++-v3/ChangeLog:
* testsuite/20_util/duration/literals/range.cc: Update expected
line of a static_assert failure.
