This is about a GIMPLE verification failure at -O2 or above because
the GIMPLE store merging pass generates a NOP_EXPR between a FP type
and an integral type. This happens when the bit-field insertion path
is taken for a FP field, which can happen in Ada for bit-packed record
types.
It is fixed by generating an intermediate VIEW_CONVERT_EXPR. The patch
also tames a little the bit-field insertion path because, for bit-packed
record types in Ada, you can end up with large bit-field regions, which
results in a lot of mask-and-shifts instructions.

AIX supports "FAT" libraries containing 32 bit and 64 bit objects

This simplifies the logic of converting Source arguments and pairs of
InputIterator arguments into the native string format. For any input
that is a contiguous range of path::value_type (or char8_t for POSIX)
a string view can be created and the conversion can be done directly,
with no intermediate allocation. Previously some cases created a
basic_string unnecessarily, for example construction from a pair of
path::string_type::iterators, or a pair of non-const value_type*
pointers.

These functions were originally static members of the path class, but

This replaces the filesystem::__detail::_Path SFINAE helper with two
separate helpers, _Path and _Path2. This avoids having one helper which
tries to check two different sets of requirements.
The _Path helper now uses variable templates instead of a set of
overloaded functions to detect specializations of basic_string or
basic_string_view.
The __not_<is_void<remove_pointer_t<_Tp1>> check is not necessary in
C++20 because iterator_traits<void*> is now empty. For C++17 replace
that check with a __safe_iterator_traits helper with partial
specializations for void pointers.
Finally, the __is_encoded_char check no longer uses remove_const_t,
which means that iterators with a const value_type will no longer be
accepted as arguments for path creation. Such iterators resulted in
undefined behaviour anyway, so it's still conforming to reject them in
the constraint checks.

Another case where we need a linker-visible symbols in order to
preserve the ld64 atom model. If these symbols are emitted as
'local' the linker cannot see that they are separate from any
global weak entry that precedes them. This will cause the linker
to complain that there is (apparently) direct access to such a
weak global, preventing it from being replaced.
This is a short-term fix for the problem - we need generic
handling for relevant cases (that also does not pessimise objects
by emitting unnecessary symbols and relocations).

In a function call expression in C++17 evaluation of the function pointer is
sequenced before evaluation of the function arguments, but that doesn't

With -fstrong-eval-order=all we evaluate the function address before the
arguments. But this caused trouble with virtual functions and
-fsanitize=vptr; we would do vptr sanitization as part of calculating the
'this' argument, and separately look at the vptr in order to find the
function address. Without -fstrong-eval-order=all 'this' is evaluated
first, but with that flag the function address is evaluated first, so we
would access the null vptr before sanitizing it.
Fixed by instrumenting the OBJ_TYPE_REF of a virtual function call instead
of the 'this' argument.

one does not need to pop after every SCC component but pop once at the end of
walk. However this breaks handling of integer_csts because they may now
become of LTO_trees block and streamed as header + body.
This bypasses the separate code for shared integer_cst streaming. I think
I want to stream everything into header and materialize the tree since it is not
part of SCC anyway.
