Add pthread_cond_reltimedwait_np (K953PF5u6Pc; computed with
tools/nid_names.py and matching aerolib.csv) as scePthreadCondTimedwait
with POSIX error numbers: ETIMEDOUT when the relative timeout expires,
EPERM when the caller does not hold the mutex, and the mutex held again on
return in every waiting case.
Titles: Porpoise PPSA99764 and RetroArch PPSA99169 import it.
Predicted from relink registry order, not observed: Porpoise stops with
"FAIL: unresolved ELF import K953PF5u6Pc from libkernel.prx" (registry

The third argument is a relative timeout in microseconds, not a
struct timespec. FreeBSD 11.4 libthr (8c639945a44588f6cfdddfb057bb5aad88735da0)
has no such function. shadPS4 (3a9f57265d28975658f1ca941daa5c879c7a74bd,
src/core/libraries/kernel/threads/condvar.cpp:229-234, 445, 467-468)
registers posix_pthread_cond_reltimedwait_np(cond, mutex, u64 usec) for this
NID and the same function for scePthreadCondTimedwait (BmMjYxmew1w), whose
microsecond argument this repository already implements. The width follows
the SCE twin's 32-bit SceKernelUseconds, as sem_reltimedwait_np does, not
shadPS4's u64. There is no timespec to validate, so no EINVAL case.

EBUSY from trylock while any thread holds the lock, EPERM from unlock by a
thread that does not hold it. libthr spins forever when the holder locks
again; that call throws here. A shared lock is allocated like a private one,
since guest code runs in one process. Recorded in TechnicalDebt.

sceKernelFsync returned the host fsync or _commit result, so a failure
returned -1 instead of an SCE error code, and a guest socket descriptor
reached the host call. fsync then set the guest errno from the host
errno rather than from that result.
Handle sockets and return SCE error codes as sceKernelFdatasync does
(EINVAL for an open socket, EBADF for a closed one or an unknown
descriptor), and have fsync take the errno from sceKernelFsync's result
like the other POSIX wrappers.

Exports pause (EDyhWelj7UY), sigwait (mrbHXqK8wkg) and sigwaitinfo
(Uq5BGthgbl4) from libkernel. NIDs computed with tools/nid_names.py and
matched in aerolib; ps5-payload-dev/sdk f5d40f02 sce_stubs/libkernel.c
places all three in libkernel.
They throw like the merged sigtimedwait (#3430), with the same message
pattern: "sigwait: waiting for a pending signal", "sigwaitinfo: waiting
for a pending signal" and "pause: waiting for a delivered signal". In
FreeBSD 11.4 (8c639945) sigwaitinfo is kern_sigtimedwait without a
timeout (sys/kern/kern_sig.c:1212), sigwait is the same wait returning
the error number (kern_sig.c:1150, lib/libthr/thread/thr_sig.c:676-728)
and pause is sigsuspend of the current mask (lib/libc/gen/pause.c:46-56).
AnyPS5 never leaves a guest signal pending (blocked signals are dropped
in Dispatch, raise delivers at once), so there is nothing to take, and
raise, kill and pthread_kill run a handler only on the calling thread,
so nothing can end a pause.
Titles (predicted stops, registry order; not observed runs):
- Ruffle PPSA68091, observed today
"FAIL: unresolved ELF import 1t1-JoZ0sZQ from libSceLibcInternal.prx"
(sinhf, #3519), predicted next
"FAIL: unresolved ELF import EDyhWelj7UY from libkernel.prx"
(pause, call site 0x8F7266).
- RetroArch PPSA99169: pause (0x30DB1, an address table entry).
- PS5MC PPSA99420: pause (0x3BD80F6, 0x3C9E220), sigwait (0x3C9E4C7),
sigwaitinfo (0x3C9E588).
- XPSemu PPSA97358: sigwait (0xE02AEC, 0x1101294, 0x1101368), QEMU's
dummy vCPU thread and sigwait_compat thread.
guest_sigtimedwait now also checks the three throws, with an empty set,
a null info, a SIGINT raised while blocked, and that neither the output
nor the blocked mask changes. TechnicalDebt records the call sites.

NativeError listed 17 Winsock and 17 POSIX errors and turned every other
one into EIO. A second connect while the first is pending (WSAEALREADY,
EALREADY) and an option the host rejects (WSAENOPROTOOPT, ENOPROTOOPT)
reached the guest as EIO; on Linux a nonblocking connect (EINPROGRESS),
a send with no destination (EDESTADDRREQ), ENOTSOCK, EAFNOSUPPORT,
EOPNOTSUPP and others did too.
The translation moves to SocketError.hpp and covers the socket errors of
both hosts by name, with the FreeBSD 11 numbers. WSAESHUTDOWN stays EPIPE
as before. socketpair's own table is gone, as NativeError covers it.

The default terminate handler formatted its whole report into a 1024-byte
buffer, so a long what() was cut off without a trailing newline. Driver
refusals that carry a serialized RecompileRequest lost most of it, and the
next log line ran into the truncated text.
The report header still goes through the bounded RawLog, and what() is
now written in full by a raw write to the stderr handle, followed by a
newline. Both keep avoiding the CRT stream lock, as before.
exception_runtime gains a forked child that throws an uncaught
runtime_error with a message over 3000 characters and checks that the
full what() reaches stderr before SIGABRT.
Vulkan starts only quads holding a non-helper lane, so the bit is set in every
lane it runs. Stray's pixel shader 0x2012f90000 keeps the packed ancillary
word where that bit is clear, and failed with an unsupported live use.

A descriptor replaced before the shared-memory path probe can otherwise
bypass the pinned-object identity check through native fallback. Compare
the negative probe's current file identity to the initial snapshot and
reject a mismatch. Exercise the earlier window with an ordinary file for
all six descriptor operations.

Not-tested: Full project build/suite, Windows runtime, console hardware and titles
Directive: Identity checks do not synchronize the entire descriptor table or identify separate opens of the same inode
Keep guest creation-mask state in libc behind C-linkage helpers so NID
patching preserves the shared exports. Reject a pinned descriptor whose
file identity differs from the snapshot taken before classification.
Exercise close and reuse from another thread at both acquisition windows

sceUserServiceGetAgeLevel reported 0. On a PS5 (firmware 13.60) the
value is the age of the user's parental restriction (0, 7, 12 and 15
measured) and 0xFFFFFFFF without one, so 0 is a user restricted to age
0. A user who is not logged in returns 0x80960009 (not logged in) with or
without an output, before the null output check.

symlink, added in #3491 while this branch was open, still resolved its
new path with ResolvePath_nid_no_patch, which now throws for an invalid
"..". Use ResolvePathError_nid_no_patch as link does, so
"missing/../x" returns ENOENT and "file/../x" ENOTDIR.
Reported by @Silverash-i8 on #3485.

Guest paths were normalized lexically before they reached the host, so
"missing/../file" and "file/../x" dropped the component before "..":
stat and open succeeded on the file, unlink deleted it and rmdir removed
a directory, where FreeBSD's lookup() resolves ".." with VOP_LOOKUP in
the directory reached so far and fails with ENOENT for a missing
component and ENOTDIR for a file. POSIX path resolution (XBD 4.13) says
the same.
".." is still collapsed lexically when the path before it is an existing
directory, so case-insensitive matching and aliases behave as before.
When it is not, the rest of the path is passed to the host unchanged and
the host resolves it. Linux then reports ENOENT or ENOTDIR as FreeBSD
does; Windows collapses ".." itself, so its results are unchanged.

GuestError passed host error values up to 34 through and reported every
other value as EIO, so readlink failed with EIO for a name that is too
long or a symbolic link loop, and a host EAGAIN would have been reported
as the guest's EDEADLK. The values whose numbering differs are now
mapped to FreeBSD's.

FreeBSD returns the difference of the lowercased bytes where the strings
differ, including where one of them ends. The guest wrappers returned the raw
difference of the terminator and the unfolded byte, so strcasecmp("ab", "A")
gave 66 instead of 98.
FreeBSD's soreceive leaves the sender unset for a stream socket, so recvfrom
returns an address length of 0 (kern_recvit). The guest call formatted the empty
host address as a 28-byte AF_INET6 sockaddr and reported length 28. Report
length 0 when the host returns no AF_INET or AF_INET6 sender, as recvmsg does.
FreeBSD's kern_clock_nanosleep writes the remaining time only when the sleep is cut short. A completed sleep zeroed rmtp, so nanosleep(&ts, &ts) in a polling loop slept zero time from the second call on.
close() of a descriptor that is not open calls _close, which raises the
UCRT invalid-parameter handler before returning EBADF. In a relinked title
that handler is libc's crash reporter, so an ordinary close of a closed
descriptor printed a FATAL report and every thread's stack. The call now
runs with the thread-local no-op handler, as dup and dup2 already do.

The abort() and UCRT invalid-parameter reports capture the stack with
RtlCaptureStackBackTrace, which stops at the first frame without unwind
data (guest code, or our libraries built without asynchronous unwind
tables), so they often end two or three frames in, before any caller.
The fault report already scans the stack for code addresses; that scan
is now a helper the backtrace reports use as well.

PPSA28416 calls it on its existing save at boot (after sceSaveDataDirNameSearch finds it) and aborted on the missing implementation. The call takes one parameter block: user id at +0, the directory name pointer at +8. Host saves have no size limit, so the conversion completes at once: an existing save returns OK, a missing one NOT_FOUND, an invalid name PARAMETER. The title polls sceSaveDataGetEventResult once afterwards and continues on 'no event'.
Goat Simulator 3 (PPSA04159) imports sce::Json::Object::find(String const&)
const (ehN1Biw3tw8), Object::iterator::operator->() const (EnesV4gXDtE) and
String::compare(char const*) const (Yfw63FVJgtU); without them the Windows
entry stub stops before the game starts with "unresolved ELF import
ehN1Biw3tw8".
find returns an iterator to the first pair whose key equals the argument,
or end(), using the same key match as Object::operator[]. operator->
returns the pair like operator*. compare orders the string against a C
string as std::string::compare does; a null argument throws.

The search returned saves in host directory order and ignored the condition's key and order. A title that asks for the newest save first (modification time, descending) got whichever directory the host listed first: the alphabetically first on NTFS, an arbitrary one on Linux. Sort by directory name, user parameter or modification time, reverse for a descending order, and reject unknown keys and orders with the parameter error, as shadPS4 does.
One queue for APR and AMM buffers kept an AMM buffer behind an APR buffer
waiting on an address that the AMM buffer writes, so neither ran.
Marvel's Wolverine does this: an APR buffer waits on a counter that the
WriteAddress commands of later AMM buffers advance, and its loading
stopped. APR and AMM buffers now keep their order within their own queue.

sceKernelGetModuleInfoFromAddr has a Windows path since 77ef75c1d, so
_sceLibcInternalForceTlsDestructor finds each dso's module there too.

Linux uses dlsym(RTLD_NEXT), and the TechnicalDebt entry no longer says
the call throws on Windows.

scePadOpen returned the standard pad's handle for a special port
(type 2) as well, and scePadGetHandle found it there. Both ports then
read the one input queue, so a press queued between two frames could be
drained by the special port's read and never reach the standard port.
PPSA16827 (Harmony's Odyssey) opens both ports for the initial user and
reads both every frame, also polling controller information and device
class data for the special one.
Special ports now return DEVICE_NOT_CONNECTED (0x80920007) from
scePadOpen, as scePadOpenExt already does because the host has no
special controller, and scePadGetHandle has no handle for them.
TechnicalDebt's scePadOpenExt entry now covers both calls.
guest_pad opens a special port before and after the standard one and
expects DEVICE_NOT_CONNECTED, and DEVICE_NO_HANDLE from scePadGetHandle
for the special port while the standard handle stays valid. It fails on
main.
PPSA16827 over 130 s of its title screen: 6812 scePadRead, 3408
scePadGetControllerInformation and 3406 scePadDeviceClassParseData calls
before, two reads of the same queue per frame; 2702 reads, one
information call and no parse calls after.
mingw's fprintf writes an unbuffered stream a character at a time and
holds the stream's lock for the whole line. The APS5_LOG_* lines that
carry a RecompileRequest ("Shader ... could not be prepared after
registration", 15-20 KB each) took one WriteFile per character, and every
other thread writing to stderr waited behind them, guest calls that log
included. Demon's Souls (PPSA01342 v1.005, Windows) stops on a black
screen after two frames on main: a BPE job worker waits for the stderr
lock in sceSaveDataDirNameSearch's trace while the shader preparation
pool prints its dumps, so GameCoreLoop never finishes a frame.
The log macros now format the line into memory and write it with one
fwrite, as Driver::reportSkip does since 8cf2f6580. The UCRT writes an
unbuffered stream's fwrite as one even-length block and the last byte,
so a line takes at most two writes on Windows and one on Linux.

sceKernelGetOperationMode returned 0 for both values, which were
unknown. A payload on a PS5 (firmware 13.60) reads mode 2 and submode 0;
nothing past the two ints is written and the result register holds no
status, so the function now returns nothing. PPSA12544 logs both values
and ignores the result.

sceKernelGetModuleInfoFromAddr found the size of the image's .eh_frame
on every call by walking all of its CIE and FDE records, checking each
against every PT_LOAD header. The guest libc's unwinder calls it for
each frame it unwinds, so a title that unwinds often walked its whole
.eh_frame hundreds of times per second.
The tables read from a .eh_frame_hdr are now kept per header address
and reused while the image stays loaded. The cache is dropped whenever
dl_iterate_phdr reports that an object was unloaded (dlpi_subs), so an
address reused by another image is read again.
guest_module_info queries a module twice and expects the same tables,
then unloads it, loads it again and expects tables of the same size at
the same offset in the new image.
PPSA16827 (Harmony's Odyssey), title screen, over 500 calls per second
counted under gdb, which slows the title: the process used 9269 CPU
samples per 10 s, 53.7% of them in this walk, and 3306 with this change,
3.2% in the lookup. The title still runs at 27 FPS; its frame rate is
limited elsewhere.
On main asin(2.0) returns 0x7ff8000000000000 and sets errno to 33;
FreeBSD msun (lib/msun/src/e_asin.c) returns 0xfff8000000000000 and
never sets errno. asin now handles |x| > 1 itself with quiet
comparisons, so a NaN input still raises no exception. For |x| <= 1
and for NaN the host function is still called.

On Windows, real thread stacks that exist before the guest arena is

The segments of the main executable and of every .guest.prx module that

On macOS, GuestWriteWatchCollectFresh reported nothing and returned true, so
MarkWritten took pages no collection had armed yet for clean, and they stayed
writable without being tracked. GuestWriteWatchCollectArmed was a full collect,
which also took those pages.
Pages now carry a fresh bit from registration until a collection takes them, as

pages, CollectArmed skips them, and Collect takes both. Protection changes, host

The write_watch fresh and armed tests check both collections.
The call was an unimplemented stub. It now writes syllable state 0 and
returns OK for every character outside the Thai block, where a PS4
firmware 11.00 libSceFont measures 1, 3 or 4; Thai characters throw as
not implemented. A null character or result returns
SCE_FONT_ERROR_INVALID_PARAMETER, and a null character writes 0 to a
non-null result, as measured. The signature follows SharpProspero.

The second argument is an out pointer to the writing's letter step, as
KytyPS5 and the SharpProspero bindings declare it. It was filled as a
letter step struct, which wrote 64 bytes over the caller's 8-byte
pointer. The letter step now lives in the writing and the call stores
its address, or null when there is no current step.

FreeBSD removes or renames a file that is still open; the descriptor stays usable. _wopen opens without FILE_SHARE_DELETE, so sceKernelUnlink returned EACCES and rename failed while the guest held a descriptor. sceKernelOpen now opens through CreateFileW with delete sharing and keeps the flag, mode and error mapping of _wopen.

The AMM ranges were reserved at the last 64 GiB of the guest arena and
the reservation threw when that window was not free. On Windows the
stacks of the threads that exist before the arena is reserved (the main
thread and the loader's workers) are placed at random addresses and are
left in the arena as host regions; when one fell in the last 64 GiB, the
first AMM use threw "fixed guest mapping ... overlaps a host region in
the guest arena". Reserve the highest free 64 GiB window instead: the
last 64 GiB when it is free, and the window just below an occupied part
of it otherwise.
Both open the same SDL capture port as sceAudioInOpen, so Input,
GetSilentState and Close work on their handles. HqOpen accepts only a
128-sample grain at 48 kHz (SharpProspero, KytyPS5); AsyncOpen returns
INVALID_SIZE above 384 samples (SharpProspero). Values the sources
disagree on throw. Format 0x10 still throws: only KytyPS5 accepts it.
Imported by FMOD-based titles, The Smurfs Dreams (PPSA21607) and Astro

sceHttp2DeleteRequest erased the request's completion queue, but
sceHttp2DeleteTemplate and sceHttp2Term removed descendant request
handles through ReleaseOwnedHandles without clearing their completion
queues. A request that completed asynchronously before its template or
context was deleted kept a stale completion that sceHttp2WaitAsync could
still consume.
ReleaseOwnedHandles now returns every transitively removed handle id, and
DeleteTemplate and Term erase the completion queue of each removed
request. CompleteAsync validates that the request is live while holding
the handle lock and inserts the completion under it, so a send that races
a deletion either returns the invalid-id error without queuing or is
erased by the deletion; a completion is no longer re-created after a
deletion returns. The only lock nesting stays handles before completions,
and no mutex is held while the user event is triggered.
GuestHttp2 covers a queued completion before sceHttp2DeleteTemplate and
before sceHttp2Term: the completion is no longer consumable, a late send
returns the invalid-id error without queuing, and the removed handles are
rejected.
An SDL controller sets the L2/R2 bit whenever its trigger axis is above
zero, and BuildData then reported 255 for any set bit, so a partly
pressed trigger read as fully pressed. Report the analog value whenever
there is one; 255 remains for an injected press and for a bit without
an analog value.

SceErrorFromErrno in the libkernel file functions passed host errno
values 1-34 through and turned every other value into EIO. Linux numbers
EAGAIN 11, which is FreeBSD's EDEADLK, so a read from an empty
non-blocking pipe returned SCE_KERNEL_ERROR_EDEADLK, and ENAMETOOLONG,
ELOOP, ENOTEMPTY, EDQUOT and EOVERFLOW, whose host values differ from
FreeBSD's, all became EIO.
Map those host values to the guest's FreeBSD numbers, as
SceIoErrorFromErrno in Open.cpp already does for EAGAIN, EDEADLK,
EDQUOT and EOVERFLOW. The guest constants the callers pass are all at
most 34 and never 11, or GUEST_ENOTEMPTY, so they are unchanged.

Clang's PS4 and PS5 targets set the default new alignment and the suitable
alignment to 32 bytes, so PS5 code may store to a fresh mspace block with
32-byte-aligned AVX instructions, as the guest heap already allows since

The guest fgets handed the size straight to the host. With a size of 0
glibc and the Windows runtime return NULL without setting errno or the
stream error indicator, and a negative size goes to the Windows
invalid-parameter path. FreeBSD's fgets checks n <= 0 before reading:
it sets __SERR on the stream, sets errno to EINVAL and returns NULL,
leaving the buffer and the file position untouched.
fgets_nid_postfix now does the same before calling the host. The
FileStream flag it uses was only set for encoding errors so far and is
renamed from SetEncodingError/encodingError to SetError/guestError; it
already stays set until clearerr like __SERR.
guest_standard_streams checks sizes 0, -1 and INT_MIN (NULL, errno 22,
error indicator set and cleared by clearerr, buffer and position
untouched) and that a following read still returns the line; it fails
without the change.

PS5MC (PPSA99420) stops at start-up on wcstok once sendfile is in. It
follows FreeBSD's three-argument wcstok over the guest's 16-bit wchar_t:
leading delimiters are skipped, the token ends at the next delimiter,
which is overwritten with 0, and *last is set to null when the string
runs out.
sceKernelAprSubmitCommandBuffer ran the whole buffer on the submitting

PS5MC (PPSA99420) stops at start-up on sendfile. It follows FreeBSD 11:
headers, the file range and trailers go to a connected stream socket, the
file offset does not move, a non-blocking socket fails with EAGAIN after
a partial send, and *sbytes reports what was sent. The checks and the
point where *sbytes is written follow kern_sendfile.c.
The guest formatter threw on %n$ and *m$, which FreeBSD's vfprintf and
glibc accept. It now reads the arguments a numbered format names into a
table first, with the types their conversions give them, and follows
FreeBSD's rules for unnumbered conversions and unnamed arguments.
FreeBSD's vfprintf takes ' as the thousands-grouping flag. The Windows
formatter threw on it as an unsupported conversion. The guest's setlocale
only accepts the C locale, which has no thousands separator, so the flag
changes nothing: it is dropped before the host's printf sees it, and the
host's locale cannot add separators.
C and FreeBSD's vfprintf print a single 0 when # meets octal zero with a
precision of 0. The Windows formatter passed the conversion to the host's
printf, which printed nothing; it now asks for one digit instead.
FreeBSD's fsync and fdatasync succeed on a descriptor opened read-only and on a directory. _commit needs write access, so both returned EBADF there. A read-only descriptor is now flushed through a write handle from ReOpenFile and a directory through a handle opened for it, as sceKernelSync already does.
Porpoise PPSA99764 stops after pthread_attr_* (#3494) with the
predicted `FAIL: unresolved ELF import h05OHOMZNMw from
libSceLibcInternal.prx` (idx 311, call site 0x8EC37); RetroArch
PPSA99169 imports it at idx 448 (call site 0xA4A27). h05OHOMZNMw is
ftrylockfile by tools/nid_names.py and aerolib.csv (zecoxao/sce_symbols
2883963a); ps5-payload-dev/sdk f5d40f02 declares
`int ftrylockfile(FILE *)` in include/freebsd/stdio.h.
ftrylockfile tries the same host CRT stream lock that flockfile,
funlockfile and every locking host stdio call on the stream take, so
no second lock exists beside the one stdio uses. It returns 0 when the
lock is acquired or already owned by the caller (recursive, released by
as many funlockfile calls) and -1 when another thread holds it, as
FreeBSD 8c639945 lib/libc/stdio/_flock_stub.c:89-104 does. Linux calls
glibc ftrylockfile. UCRT has no try variant of _lock_file, so Windows
calls TryEnterCriticalSection on the CRITICAL_SECTION that _lock_file
enters (__crt_stdio_stream_data::_lock, ucrt/inc/corecrt_internal_stdio.h,
same layout in Windows SDK 10.0.19041, 10.0.22621 and 10.0.26100). A
null or closed stream throws. The UCRT layout dependency is recorded in
TechnicalDebt.
guest_standard_streams covers trylock on an unlocked stream, re-entry
by the owner, failure from another thread while held (also after one of
two unlocks and while another thread holds flockfile), stdio calls
from another thread blocking on the trylock-held lock, release order,
and null and closed streams.

The f16 forms of v_fma_mix threw for any FLOAT_MODE with an f16 rounding
other than to nearest even. ps5-opengl's shaders run with FLOAT_MODE
0xcc, f16 rounding toward zero with f16 denormals kept, so PPSA99005
stopped at its first draw (#2631).
The exact product-sum, already computed in f64 with round to odd, is now
rounded once in the mode's direction: scaled by the f16 step at its
exponent, truncated, floored or ceiled, and scaled back. A result beyond
65504 becomes infinity or 65504 as IEEE 754 gives for the direction. On
RDNA2 (gfx1036) -1.5 * 2^-24 + 2^-126 gives 0x8002 with round toward
-infinity, and this gives the same. Flushed f16 denormals still throw.

realloc: it reallocates through the application heap, and when realloc
fails (the application allocator returns null or the default heap
rejects the size) it frees the block through the same allocator, sets
ENOMEM and returns null. Size 0 frees and returns null as realloc does
here, so the block is not freed twice. Other heap failures throw, as
for realloc. The NID matches tools/nid_names.py and aerolib.
The application heap tests cover grow, shrink, a null pointer, size 0
and failure with both the replacement and the default allocator.

XPSemu (PPSA97358) stops next at sigsetjmp (aRo9AhFUXcM) from libkernel,
per the body of #3323 "feat(libkernel): implement cpuset_setaffinity for
the calling thread or process": "XPSemu: with this PR, the next stop is
`sigsetjmp` (`aRo9AhFUXcM`)". RetroArch and PS5MC list it under libkernel
in the absent-import tables of #1578; aerolib names aRo9AhFUXcM sigsetjmp.
sigsetjmp is FreeBSD's amd64 sigsetjmp (lib/libc/amd64/gen/sigsetjmp.S,
release/11.4.0 8c639945), the counterpart of the merged siglongjmp (#2935)
and its sigjmp_buf layout (sys/x86/include/setjmp.h, _JBLEN 12): it stores
savemask at offset 88 and, when it is nonzero, saves the current mask at 72
through _sigprocmask(SIG_BLOCK, NULL, oset); then it records the return
address, rbx, rsp, rbp, r12-r15 and the x87 control word, and returns 0.
guest_signal_sets now jumps through the export instead of its copy of
FreeBSD's sigsetjmp, and checks that savemask 0 leaves the mask slot
untouched, a nonzero savemask records the current mask and its own value,
and the callee-saved registers come back after siglongjmp.

Register copied the protection it had recorded for pages it already
watched over the protection the kernel had just reported. A guest that
reserves address space, which registers it as PROT_NONE, then maps
direct memory over it read-write and registers it again kept the stale
PROT_NONE. Collect only write-protects pages with PROT_WRITE, so writes
to that memory were reported once and never again. With PPSA12544 on
the macOS port, the title menu text blinked and glyphs went missing.
Register now keeps a recorded protection only where its own write
protection explains what the kernel reports, and takes the kernel's
protection otherwise. A protected page that was mapped again also loses
its protected mark, so erase no longer restores the old protection over
the new mapping. The kernel is read under the lock, so a concurrent
Collect cannot protect a page between the read and the merge.
Test write_watch_mapped: a reservation, a mapping over it and a second
registration keep reporting writes, and a protected page reserved again
stays PROT_NONE.
