We currently declare __builtin_source_location with a const void* return
type instead of the actual type const std::source_location::__impl*, and
later when folding this builtin we obtain the actual type via name lookup.
But the below testcase demonstrates this approach seems to interact
poorly with modules, since we may import an entity that uses
std::source_location::current() in its default argument (or DMI) without
necessarily importing <source_location>, and thus the name lookup for
std::source_location will fail at the call site (when using the default
argument) unless we also import <source_location>.
This patch fixes this by instead initially declaring the builtin with an
auto return type and updating it appropriately upon its first use (in
standard code the first/only use would be in the definition of
std::source_location). Thus when folding calls to this builtin we can
get at its return type through the type of the CALL_EXPR and avoid
needing to do a name lookup.

In extract_autos_r, we need to recompute TYPE_CANONICAL for the template
type parameter after adjusting its index, otherwise we end up with a
comptypes ICE for the below testcase. Note that such in-place type
adjustment isn't generally safe to do since the type could be the
TYPE_CANONICAL of another (unadjusted) type, but in this case the
canonical auto (of some level and 0 index) is the first auto (of that
level) that's created, and so any auto that we do end up adjusting can't
be the canonical one.

Both C99 and latest C2X say that compound literal shall have an object type
(complete object type in the latter case) or array of unknown bound,
so complit with function type is invalid. When the initializer had to be
non-empty for such case, we used to diagnose it as incorrect initializer,
but with (fntype){} now allowed we just ICE on it.
The following patch diagnoses that.

The ACLE requires that __ARM_FEATURE_CLZ be defined if the hardware

This patch is to support VSETVL PASS for RVV support.
1.The optimization and performance is guaranteed LCM (Lazy code motion).
2.Base on RTL_SSA framework to gain better optimization chances.
3.Also we do VL/VTYPE, demand information backward propagation across
blocks by RTL_SSA reverse order in CFG.
4.It has been well and fully tested by about 200+ testcases for VLMAX
AVL situation (Only for VLMAX since we don't have an intrinsics to
test non-VLMAX).
5.Will support AVL model in the next patch.
gcc/ChangeLog:
* config.gcc: Add riscv-vsetvl.o.
* config/riscv/riscv-passes.def (INSERT_PASS_BEFORE): Add VSETVL PASS
location.

On top of the just posted patch, this patch makes sure that
any % chars in message strings aren't treated as format chars.
None of these functions take variable number of arguments, so for
most of format specifiers there is nowhere to take arguments from,
it is true that a couple of format specifiers don't take any
arguments - %%, %m, %<, %>, %' - so it is actually possible
to use them, but one needs to verify that no other are emitted and
that what should be printed as % is really emitted as %%.
If the FE does that, then please ignore this patch, otherwise I think
it is safer to do this.

Call functions with "%s", message rather than just message, so that
% chars in message aren't treated as format specifiers.
As mentioned in the PR, bootstrap with m2 enabled currently fails
on powerpc64le-linux, we get weird ICE after printing some diagnostics.
The problem is that mc creates from *.def prototypes like
extern void m2linemap_WarningAtf (m2linemap_location_t location, void * message);
but the actual function definitions use
void m2linemap_WarningAtf (m2linemap_location_t location, void * message,
...) { code }
and on powerpc64le-linux such lying about the prototype results in
wrong-code, on the caller side we assume the function isn't varargs
and so don't reserve 64 bytes in the frame for it, while the callee
relies on the area being reserved and stores into it.
Fixed by adding non-stdarg wrappers around stdarg functions (because
we want va_list and pass it to diagnostics functions).

For -fsanitize={address,thread,leak} we link into binaries
lib*san_preinit.o such that the -lasan, -ltsan or -llsan libraries
are initialized as early as possible through .preinit_array.
The hwasan library has the same thing, but we strangely compiled
it into the library (where it apparently didn't do anything,
.preinit_array doesn't seem to be created for shared libraries),
rather than installing it like in the other 3 cases.
The following patch handles it for hwasan similarly to asan, tsan and lsan.
I don't have any hw with hwasan support, so I've just checked it

Here we're rejecting the use of the lambda capture of 't' (of empty
type) as a template argument ultimately because convert_nontype_argument
checks constantness using is_constant_expression, which returns false
for lambda captures since want_rval=false. But in this case I believe
an lvalue-to-rvalue conversion of the argument is implied, so we should
be using is_rvalue_constant_expression instead (which would return true
here).
However, it doesn't seem necessary to consider constantness at all
when deciding whether to instantiate a non-dependent argument in
convert_nontype_argument. So this patch gets rid of the problematic
constantness test altogether, which incidentally also fixes the similar
dg-ice'd testcase from PR87765. This is in line with a similar
change we made to finish_decltype_type in r12-7564-gec0f53a3a542e7.

When registering an unwind frame with __register_frame_info_bases
we currently initialize that fde object eagerly. This has the
advantage that it is immutable afterwards and we can safely
access it from multiple threads, but it has the disadvantage
that we pay the initialization cost even if the application
never throws an exception.
This commit changes the logic to initialize the objects lazily.
The objects themselves are inserted into the b-tree when
registering the frame, but the sorted fde_vector is
not constructed yet. Only on the first time that an
exception tries to pass through the registered code the
object is initialized. We notice that with a double checking,
first doing a relaxed load of the sorted bit and then re-checking
under a mutex when the object was not initialized yet.
Note that the check must implicitly be safe concering a concurrent
frame deregistration, as trying the deregister a frame that is
on the unwinding path of a concurrent exception is inherently racy.
libgcc/ChangeLog:
* unwind-dw2-fde.c: Initialize fde object lazily when
the first exception tries to pass through.
When registering a dynamic unwinding frame the fde list is sorted.
Previously, we split the list into a sorted and an unsorted part,
sorted the later using heap sort, and merged both. That can be
quite slow due to the large number of (expensive) comparisons.
This patch replaces that logic with a radix sort instead. The
radix sort uses the same amount of memory as the old logic,
using the second list as auxiliary space, and it includes two
techniques to speed up sorting: First, it computes the pointer
addresses for blocks of values, reducing the decoding overhead.
And it recognizes when the data has reached a sorted state,
allowing for early termination. When running out of memory
we fall back to pure heap sort, as before.

return 0;

This fixes some bugs in the swap functions for std::expected.
It also disables the noexcept-specifiers for equality operators, because
those are problematic when querying whether a std::expected is equality
comparable. The operator==(const expected<T,E>&, const U&) function is
not constrained, so is viable for comparing expected<T,E> with
expected<void,G>, but then we get an error from the noexcept-specifier.

This adds a static assertion to std::allocator_traits::rebind_alloc to
diagnose violations of the rule that rebinding an allocator to its own
value type yields the same allocator type.
This helps to catch the easy mistake of deriving from std::allocator but
forgetting to override the rebind behaviour (no longer an issue in C++20
as std::allocator doesn't have a rebind member that can be inherited).
It also catches bugs like in 23_containers/vector/52591.cc where a typo
means the rebound allocator is a completely different type.
I initially wanted to put this static assert into the body of
allocator_traits:
static_assert(is_same<rebind_alloc<value_type>, _Alloc>::value,
"rebind_alloc<value_type> must be Alloc");
However, this causes a regression in the test for PR libstdc++/72792.
It seems that instantiating std::allocator_traits should be allowed for
invalid allocator types as long as you don't try to rebind them. To
support that, only assert in the __allocator_traits_base::__rebind class
template (in both the primary template and the partial specialization).
As a result, the bug in 20_util/scoped_allocator/outermost.cc is not
diagnosed, because nothing in that test rebinds the allocator.
