PR libstdc++/89345 Only define std::destroying_delete for C++2a
Clang defines the __cpp_impl_destroying_delete macro unconditionally, so
that the feature is supported whenever the library type is defined. This
is incompatible with the current definition in libstdc++ because we use
constexpr and inline variables, which will give an error for older -std
modes.
This patch defines the destroying_delete_t type and destroying_delete
variable independently of the __cpp_impl_destroying_delete macro, but
only for C++2a (because the names aren't reserved for previous
standards). The __cpp_lib_destroying_delete macro is only defined when
both the library type and compiler macro are defined (i.e. when the type
can actually be used as intended).

[PR87322] move cp_evaluated up to tsubst all lambda parms
A lambda capture variable initialized with a lambda expr taking more
than one parameter got us confused.
The first problem was that the parameter list was cut short during
tsubsting because we tsubsted it with cp_unevaluated_operand. We
reset it right after, to tsubst the function body, so I've moved the
reset up so that it's in effect while processing the parameters as
well.
The second problem was that the lambda expr appeared twice, once in a
decltype that gave the capture variable its type, and once in its
initializer. This caused us to instantiate two separate lambda exprs
and closure types, and then to flag that the lambda expr in the
initializer could not be converted to the unrelated closure type
determined for the capture variable. Recording the tsubsted expr in
the local specialization map, and retrieving it for reuse fixed it.
However, that required some care to avoid reusing the lambda expr
across different indices in pack expansions.

AArch64: Allow any offset for SVE addressing modes before reload.
On AArch64 aarch64_classify_address has a case for when it's non-strict

This because reload would later make the address valid. SVE however requires
the address always be valid, but currently allows any address when a MEM +

makes sense to avoid allocating an underlying array at all if there are no
elements and instead use a null pointer, like the initializer_list default
constructor.
If the (automatic storage duration) list does have initializer elements, we
continue to reject the declaration, because the initializer_list ends up
referring to an automatic storage duration temporary array, which is not a
suitable constant initializer. If we make it static, it should be OK
because we refer to a static array. The second hunk fixes that case. It

We can load zeros with narrower instruction, (e.g. 256 bit by inherent

Fix splay tree KEY leak detected in GDB test gdb.base/macscp.exp
When a node is removed from a splay tree, the splay tree was
not using the function splay_tree_delete_key_fn to release the key.
This was causing a leak, fixed by Tom Tromey.
This patch fixes another key leak, that happens when a key equal to
a key already present is inserted. In such a case, we have to release
the old KEY.
Note that this is based on the assumption that the caller always
allocates a new KEY when doing an insert.
Also, clarify the documentation about when the release functions are
called.

linemap_line_start: protect against location_t overflow (PR lto/88147)
PR lto/88147 reports an assertion failure due to a bogus location_t value
when adding a line to a pre-existing line map, when there's a large
difference between the two line numbers.
For some "large differences", this leads to a location_t value that exceeds
LINE_MAP_MAX_LOCATION, in which case linemap_line_start returns 0. This
isn't ideal, but at least should lead to safe degradation of location
information.
However, if the difference is very large, it's possible for the line
number offset (relative to the start of the map) to be sufficiently large
that overflow occurs when left-shifted by the column-bits, and hence
the check against the LINE_MAP_MAX_LOCATION limit fails, leading to
a seemingly-valid location_t value, but encoding the wrong location. This
triggers the assertion failure:
linemap_assert (SOURCE_LINE (map, r) == to_line);
The fix (thanks to Martin) is to check for overflow when determining
whether to reuse an existing map, and to not reuse it if it would occur.

After the register allocator changes of r268705 we need to update a few tests

In all cases the compiler is now generating the expected code, since the tests
are all float16 testcases using a hard-floar abi, we expect that actual fp16
instructions are used rather than using integer loads and stores. Because of
we also save on some mov.f16s that were being emitted before to move between

[RS6000] Correct save_reg_p
Fixes lack of r30 save/restore on
// -m32 -fpic -ftls-model=initial-exec
__thread char* p;
char** f1 (void) { return &p; }
and
// -m32 -fpic -msecure-plt
extern int foo (int);
int f1 (int x) { return foo (x); }
These are both caused by save_reg_p returning false when the pic
offset table reg (r30 for ABI_V4) was used, due to the logic not
exactly matching that in rs6000_emit_prologue to set up r30.
I also noticed that save_reg_p isn't following the comment regarding
calls_eh_return (since svn 267049, git
0edf78b1b2a0), and the comment
needs tweaking too. For why the revised comment is correct, grep for
saves_all_registers in lra.c, and yes, we do want to save the pic
offset table reg for eh_return.

S/390: Introduce jdd constraint
Implementation of section anchors in S/390 back-end added in r266741
broke jump labels in S/390 Linux kernel [1]. Currently jump labels
pass global variable addresses to .quad directive in inline assembly
using "X" constraint. In the past this used to produce regular symbol
references, however, after r266741 we sometimes get values like
(plus (reg) (const_int)), where (reg) points to a section anchor.
Strictly speaking, this is still correct, since "X" accepts anything.
Thus, now we need another way to support jump labels.
The existing "i" constraint cannot be used, since with -fPIC it must
not accept non-local symbols, however, jump labels do require that,
e.g. __tracepoint_xdp_exception from kernel proper might be referenced
from kernel modules.
The existing "ZL" constraint cannot be used for the same reason.
The existing "b" constraint cannot be used because of the way
expand_asm_stmt works. It deduces whether the constraint allows
regs, subregs or mems, and processes asm operands differently based on
that. "b" is supposed to accept values like (mem (symbol_ref)), and
there appears to be no way to explain to expand_asm_stmt that for "b"
mem's address must not be in a register.
This patch introduces the new machine-specific constraint named "jdd" -
"j" prefix is already used for constants, and "d" stands for "data".
It accepts anything that fits into the data section, whether or not
this might require a relocation, that is, anything that passes
CONSTANT_P check.
