Jonathan Wakely f505f37a8e libstdc++: Define _GNU_SOURCE for secure_getenv on Cygwin [PR107511]
As in r12-6867-ge20486d508afdf we need to define _GNU_SOURCE explicitly
for Cygwin, because configure finds it in libc but it isn't declared
unless we request it.

libstdc++-v3/ChangeLog:

	PR libstdc++/107511
	* libsupc++/eh_alloc.cc (_GNU_SOURCE): Define.

Jonathan Wakely 0dd9dd1fdf libstdc++: Disable all emergency EH pool code if obj-count == 0
For a zero-sized static pool we can completely elide all code for the EH
pool.

We no longer need to adjust the static buffer size to ensure at least
one free_entry can be created in it, because we no longer use a static
buffer at all if obj_count == 0. If the buffer exists, obj_count >= 1
and the buffer will be much larger than sizeof(free_entry).

libstdc++-v3/ChangeLog:

	* libsupc++/eh_alloc.cc [USE_POOL]: New macro.
	[!USE_POOL] (__gnu_cxx::__freeres, pool): Do not define.
	[_GLIBCXX_EH_POOL_STATIC] (pool::arena): Do not use std::max.
	(__cxxabiv1::__cxa_allocate_exception) [!USE_POOL]: Do not use
	pool.
	(__cxxabiv1::__cxa_free_exception) [!USE_POOL]: Likewise.
	(__cxxabiv1::__cxa_allocate_dependent_exception) [!USE_POOL]:
	Likewise.
	(__cxxabiv1::__cxa_free_dependent_exception) [!USE_POOL]:

Jonathan Wakely 23c3cbaed3 libstdc++: Fix bootstrap for --disable-threads build [PR107221]
The __scoped_lock type should be used unqualified so that we always
refer to pool::__scoped_lock, which might be the dummy fallback
implementation.

The __mutex and __scoped_lock types in <ext/concurrence.h> already work
fine without __GTHREADS being defined, but that header isn't included at
all unless _GLIBCXX_HOSTED != 0. The fallback implementation should be
used for ! _GLIBCXX_HOSTED instead of for !defined __GTHREADS.

libstdc++-v3/ChangeLog:

	PR bootstrap/107221
	* libsupc++/eh_alloc.cc (pool): Change preprocessor condition
	for using __mutex from __GTHREADS to _GLIBCXX_HOSTED.
	(pool::allocate): Remove namespace qualification to use
	pool::__scoped_lock instead of __gnu_cxx::__scoped_lock.

Jonathan Wakely 637e3668fd libstdc++: Allow emergency EH alloc pool size to be tuned [PR68606]
Implement a long-standing request to support tuning the size of the
emergency buffer for allocating exceptions after malloc fails, or to
disable that buffer entirely.

It's now possible to disable the dynamic allocation of the buffer and
use a fixed-size static buffer, via --enable-libstdcxx-static-eh-pool.
This is a built-time choice that is baked into libstdc++ and so affects
all code linked against that build of libstdc++.

The size of the pool can be set by --with-libstdcxx-eh-pool-obj-count=N
which is measured in units of sizeof(void*) not bytes. A given exception
type such as std::system_error depends on the target, so giving a size
in bytes wouldn't be portable across 16/32/64-bit targets.

When libstdc++ is configured to use a dynamic buffer, the size of that
buffer can now be tuned at runtime by setting the GLIBCXX_TUNABLES
environment variable (c.f. PR libstdc++/88264). The number of exceptions
to reserve space for is controlled by the "glibcxx.eh_pool.obj_count"
and "glibcxx.eh_pool.obj_size" tunables. The pool will be sized to be
able to allocate obj_count exceptions of size obj_size*sizeof(void*) and
obj_count "dependent" exceptions rethrown by std::rethrow_exception.

With the ability to tune the buffer size, we can reduce the default pool
size on 32-bit and 16-bit targets. Most users never need to throw 1kB
exceptions in parallel from hundreds of threads after malloc is OOM. The
users who do need that can use the tunables to select larger sizes.

The old defaults can be chosen at runtime by setting GLIBCXX_TUNABLES
to:
64-bit: glibcxx.eh_pool.obj_count=64:glibcxx.eh_pool.obj_size=112
32-bit: glibcxx.eh_pool.obj_count=32:glibcxx.eh_pool.obj_size=104

Or approximated by configuring with:
64-bit: --with-libstdcxx-eh-pool-obj-count=252
32-bit: --with-libstdcxx-eh-pool-obj-count=94

Keef Aragon 5bc2042df4 Fix bug in emergency cxa pool free
This probably has never actually affected anyone in practice. The normal
ABI implementation just uses malloc and only falls back to the pool on
malloc failure. But if that happens a bunch of times the freelist gets out
of order which violates some of the invariants of the freelist (as well as
the comments that follow the bug). The bug is just a comparison reversal
when traversing the freelist in the case where the pointer being returned
to the pool is after the existing freelist.
