As of r325320 posix_fallocate on a ZFS filesystem returns EINVAL to
indicate that the operation is not supported. (I think this is a strange
choice of errno on the part of POSIX.)

linked with AddressSanitizer (even those linked on earlier versions of
FreeBSD, or with external versions of clang) started failing with errors
similar to:
==14688==AddressSanitizer CHECK failed:
/usr/src/contrib/compiler-rt/lib/asan/asan_poisoning.cc:36
"((AddrIsAlignedByGranularity(addr))) != (0)" (0x0, 0x0)
This is because AddressSanitizer expects all the TLS data in the program
to be aligned to at least 8 bytes.
Before the jemalloc 5.0.0 update, all the TLS data in the i386 version
of libc.so added up to 80 bytes (a multiple of 8), but 5.0.0 made this
grow to 2404 bytes (not a multiple of 8). This is due to added caching
data in jemalloc's internal struct tsd_s.
To fix AddressSanitizer, ensure this struct is aligned to at least 16
bytes, which can be done unconditionally for all architectures. (An
earlier version of the fix aligned the struct to 8 bytes, but only for
ILP32 architectures. This was deemed unnecessarily complicated.)

AArch64: account for possible frame index operand in compares.
If the address of a local is used in a comparison, AArch64 can fold
the address-calculation into the comparison via "adds".
Unfortunately, a couple of places (both hit in this one test) are not
ready to deal with that yet and just assume the first source operand
is a register.
This should fix an assertion failure while building the test suite of
www/firefox for AArch64.

If unwinding stops due to hitting the end of the call chain, the return
value is supposed to be _URC_END_OF_STACK; other values indicate internal
errors. The return value from get_eit_entry() is now returned without
translating it to _URC_FAILURE, so that callers can see _URC_END_OF_STACK
when it happens.
When raising an exception, the unwinder searches for a catch handler and if
none is found it should invoke std::terminate() with the uncaught exception
as the "current" exception. Before this change, the terminate handler was
invoked with no exception as current (abi::__cxa_current_exception_type()
returned NULL), because the return value from the unwinder indicated an
internal failure in unwinding. It turns out that was because all errors
from get_eit_entry() were translated to _URC_FAILURE. Now the error is
returned untranslated, which allows _URC_END_OF_STACK to percolate upwards
to throw_exception() in libcxxrt. When it sees that return status it
properly calls std::terminate() with the uncaught exception installed
as the current exception, allowing custom terminate handlers to work
with it.
echo | awk 'BEGIN {i=$1; print i}' prints a boatload of stack
garbage. NUL terminate the memory returned from malloc to prevent it.

Permit a deflateParams() parameter change as soon as possible.
This change fixes compression errors seen when the embedded Tomcat
web server of a UniFi Controller zlib compresses responses. Given
that Tomcat just uses Java/OpenJDK which in turn employs zlib for
its compression/decompression support, this bug might very well
affect other applications, too.

where the source register is also the first destination register.
If this is the case, and we raise an exception in the middle of the
instruction, for example the load is across two pages and the second page
isn't mapped, QEMU will have overwritten the address with invalid data.
This is a valid behaviour in most cases, with the exception of when a
destination register is also use in address generation. As such switch
the order of the registers to ensure the address register is second so it
will be written to second, after any exceptions have happened.
This has been acknowledged in upstream QEMU, however as the workaround is
simple also handle it here.
