qsort was a heapsort. It sorted correctly, but elements that compare
equal ended in a different order from FreeBSD's Bentley-McIlroy qsort,
in 18947 of 20000 random arrays with repeated keys, and below 7
elements, where FreeBSD's insertion sort keeps equal elements in
place, a heapsort does not. qsort now follows FreeBSD 11 qsort.c,
including its comparator call sequence.

PS4 executables keep their relocated read-only data, GOT and init/fini
arrays in a PT_SCE_RELRO segment outside every PT_LOAD. The segment filter
dropped it, so Windows and macOS output stopped at the first relocation
into it, and Linux output placed the relinker's extra block over its
addresses without an error. The ELF reader now reports such a segment as a
read-write PT_LOAD. A PT_SCE_RELRO inside a PT_LOAD keeps being skipped,
and one that partially overlaps a PT_LOAD throws.

The Windows unwinder stopped at the first frame of a module without the
project's .ehmeta or .ehfram tables, so an exception could not cross
libstdc++-6.dll and libwinpthread-1.dll (std::call_once through
pthread_once) or system DLLs. For such a frame it now looks up the
function's PE unwind data with RtlLookupFunctionEntry and takes the
caller's registers, including the nonvolatile rsi, rdi and xmm6-xmm15,
from RtlVirtualUnwind. A frame whose unwind data has an exception or
termination handler still stops the walk, since those handlers are not
run.
windows_exceptions gets back the std::call_once case of #1423.

sceSaveDataDirNameSearch reads % in the directory name pattern as any
run of characters and _ as one character. The matcher stopped when the
name ran out and then required the pattern to have ended too, so a
trailing % with nothing left to match failed: SAVEDATA% did not find a
save named SAVEDATA, and TRAI_% did not find TRAIL. A % now matches no
characters at the end of a name as it already did in the middle.
lavapipe and MoltenVK leave the vertex stage out of subgroupSupportedStages,
so the driver's shader validation refuses every vertex program that declares
GroupNonUniform ("subgroup capability 61 is unsupported for shader stage 1").
Most do, since the entry EXEC is a ballot.
The device target now records whether the vertex stage has subgroups. When
it does not, vertex and local programs get a host subgroup width of 1: s3
reports one vertex and one primitive, the lane id is 0, a ballot is the
invocation's own bit, a shuffle returns the invocation's value, an elect is
true and a half-wave reduction read is the key itself. Reads of other lanes
keep the existing narrow-host rules and throw where they did. Devices with
vertex subgroups emit the same SPIR-V as before.
The memo stamp held TrackerGeneration, which every collect and driver store
advances, so it almost never matched. Driver stores into uncovered ranges
record their generation per 64 KiB block, and NewestStamp of the surface
replaces TrackerGeneration in the stamp.
Kart PS5 (PPSA99611, Phi1ow/mkwii-ps5 v1.0.0-rc1) stops on it right
after __divti3. The related open PR #4037 reports: "with this change it
passes `__divti3` and stops at `ELSr5qm4K1M` (`__umodti3`)".
PS5CEMU-HAR (PPSA99360) imports it too: tools/import_audit.py lists
ELSr5qm4K1M __umodti3 as absent from libSceLibcInternal.prx (registry
index 359), so the predicted stop is
"FAIL: unresolved ELF import ELSr5qm4K1M from libSceLibcInternal.prx".
libSceLibcInternal imports fall back to libc.prx, so the export lives in
libc beside __udivti3. compute_nid and aerolib (zecoxao/sce_symbols
2883963a) both give ELSr5qm4K1M = __umodti3.
__umodti3 is compiler-rt's lib/builtins/umodti3.c (llvm-project
0ee439b705e82a4fe20e266bc8fea96d0e60e1ec): the remainder that
__udivmodti4 leaves. The restoring division of SonyUdivti3 already
computes it, so the loop moves to SonyUdivmod128 and both helpers use
it. A zero divisor reaches a 64-bit divide in __udivmodti4 and traps on
x86-64; this throws instead, as __udivti3 does, and names the dividend.

A relocation whose dynamic symbol entry is all zero, like the null symbol,
now takes the value 0 plus its addend, as the gABI defines for STN_UNDEF.
The Linux output imports such an entry as an unnamed weak symbol, which the
host loader resolves to 0. The Windows and macOS outputs write the value
into the slot instead of failing with "Empty import symbol name". Such
references are left out of the call registry. An unnamed symbol entry that
is not all zero still fails the relink.
OliSe Player (PPSA01153) has seven of these entries and calls through the
slots only when they are not 0 (#4437).

sceHttp2DeleteCookieBox(cookieBoxId) erases the box from the handle
registry sceHttp2CreateCookieBox adds it to and returns 0, or the
library's invalid-id error (0x817B1100) for an id that is not a live
cookie box. The signature follows SharpProspero and the behaviour

RetroArch 1.0.0-beta.1 (PPSA99169) stops on main 0f863c10 at
FAIL: unresolved ELF import Nx-F5v0-qU8 from libSceLibcInternal.prx
Nx-F5v0-qU8 is asinl (tools/nid_names.py, aerolib).
The implementation follows the asinl of the libc.prx bundled with
PPSA28319, read from its disassembly: FreeBSD msun's e_asinl.c with
the ld80 invtrig.c coefficients (9f043204), which the binary holds as
the same 80-bit constants, computed in the x87 long double the guest
uses. +-1 returns +-pi/2 rounded to 64 bits and +-0 keeps its sign.
For |x| > 1, the infinities and NaN, Sony's error helper raises
FE_INVALID and sets errno to EDOM before returning (x - x) / (x - x),
so a NaN argument sets EDOM too.
20 million random arguments in (-1, 1) plus the branch edges give the
same bits as that code from the title's libc.prx run on a Windows
host. guest_math pins a set of those bits and checks the domain
errors' errno and FE_INVALID, and that errno is untouched otherwise.

Ruffle Flash 1.2.0 (PPSA68091) stops on main 0f863c10 at
FAIL: unresolved ELF import 1t1-JoZ0sZQ from libSceLibcInternal.prx
1t1-JoZ0sZQ is sinhf (tools/nid_names.py, aerolib). RetroArch
1.0.0-beta.1 (PPSA99169) imports it as well.
The implementation follows the sinhf of the libc.prx bundled with
PPSA28319, read from its disassembly: FreeBSD msun's e_sinhf.c as of
5aa554c7 (before __ldexp_expf, so expf(|x| / 2) is squared between
logf(FLT_MAX) and the overflow threshold), calling msun stable/9
expm1f and expf (59bc2f09), whose paths for the arguments sinhf passes
are inlined. Past the threshold Sony's error helper sets errno to
ERANGE before returning x * 1e37; NaN and the infinities return x + x
and leave errno alone.
Running that code from the title's libc.prx on a Windows host gives
the same bits as this implementation for every finite argument up to
the threshold, both signs (2,238,032,378 inputs). guest_math pins a
set of those bits, the overflow errno and FE_OVERFLOW, and checks that
errno is untouched otherwise.

On Linux sscanf, vsscanf, fscanf and sscanf_s hand their conversions to
glibc. Since glibc 2.38, code built as GNU C++ calls the C23 entry
points (__isoc23_vsscanf, __isoc23_vfscanf, __isoc23_sscanf), whose %i
reads a 0b/0B binary prefix. On main,
sscanf("0b101 x", "%i%n%7s", &value, &end, rest) stores value 5 and
end 5 and leaves "x" for the %s; " -0B11" gives -3. TechnicalDebt
records this.
FreeBSD's %i knows only the 0 and 0x prefixes. FreeBSD 11.4
lib/libc/stdio/vfscanf.c, parseint, lines 345-353 and 371-380:
case '0':
if (base == 0) {
base = 8;
flags |= PFXOK;
}
...
/* letters ok iff hex */
case 'A': case 'B': case 'C':
case 'D': case 'E': case 'F':
case 'a': case 'b': case 'c':
case 'd': case 'e': case 'f':
/* no need to fix base here */
if (base <= 10)
break; /* not legal here */
so "0b101" stores 0, consumes the "0" and leaves "b101", as C17 does
and as the strtol family here already does.
With glibc the scanf family now calls __isoc99_vsscanf and
__isoc99_vfscanf, the entry points GNU C++ used before glibc 2.38
(exported since 2.7), which read %i without the binary prefix. Other
hosts keep std::vsscanf and std::vfscanf. The TechnicalDebt entry is
removed.

MaskedSelectEliminator walked forward from each select to see whether the
lanes its mask excludes are read. Since fda4aa90 the walks pass explicit-LOD
gathers, size queries and guarded image writes, so in a large pixel shader
most of them cover the rest of the program, and the cost grows with the
square of its size (#3504).
The pass now computes, for every value, the set of masks under which it is
unread, from its uses backwards: a use guarded by a condition contributes the
masks that condition implies, a lane-local use adds what its result is unread
under, and any other use contributes nothing. A select is dropped when its
mask is in its own set. Loops are solved as strongly connected components.
The rules for guards, lane-local uses, loops, whole quad masks, selected
execs, rebuilt mask words and guarded first-lane reads are the ones the walk
applied. A first-lane read passes the masks its read mask implies when its
own result is unread outside that read mask, which is solved once per read in
the same way. The walk's step limit, its 64-level implication depth and its
first-lane nesting depth are gone, so a proof no longer depends on the order
of the questions.
Goat Simulator 3 draws a triangle list whose indices are all 0xffffffff
with primitive restart off. Each fetch past a descriptor's records reads
zeros (out-of-bounds select 0 or 1), but the zero-padded vertex copies
were sized to the highest index: 160 GiB, which vkAllocateMemory refused.
When the highest index is at least 64Ki vertices past the largest
per-vertex record count, the draw now uses a copy of its indices with
every index past that count moved to it. Each attribute reads zeros
there as at the original index; only the vertex index the shader sees
changes, so indices closer to the records are left as they are.

FIONREAD x2, TIOCGWINSZ x3), ProsperoTV (PPSA99003, FIONBIO on a pipe
once poll on pipes is in), XPSemu (PPSA97358, 21 sites).
Following FreeBSD 11.4 kern_ioctl (sys/kern/sys_generic.c:758),
vn_ioctl (sys/kern/vfs_vnops.c:1488), pipe_ioctl (sys/kern/sys_pipe.c:1346)

fcntl and sceKernelFcntl answered EBADF (sceKernelFcntl threw) for
every descriptor outside the libSceNet socket table, so files, pipes,
directories and descriptors 0 to 2 could not be queried or changed.
Observed: Yamagi Quake II (PPSA99007) stops with
"Sys_Error: change stdin to blocking Bad file descriptor", from
fcntl(fileno(stdin), F_SETFL, fcntl(0, F_GETFL, 0) & ~FNDELAY)
(yquake2 src/backends/unix/system.c:81-86).
Predicted from the titles' sources and decoded call sites: XPSemu
(PPSA97358, 97 fcntl sites: F_GETFD 12, F_SETFD 20, F_GETFL 8,
F_SETFL 9, F_DUPFD 1, F_DUPFD_CLOEXEC 7, F_GETLK 9) fails in
qemu_init_main_loop, where its pipe2 (pipe plus F_SETFD FD_CLOEXEC) and
glib's g_unix_set_fd_nonblocking (F_GETFL, F_SETFL) build the event
notifier (util/event_notifier-posix.c:44-67); VLC (PPSA85300, 43 sites,
F_RDAHEAD on every file it opens), RetroArch (PPSA99169, 17),
Porpoise (PPSA99764, 13) and Ruffle (9) call it on files and pipes.
The commands follow FreeBSD 11.4 kern_fcntl and kern_dup
(sys/kern/kern_descrip.c:479-799, 812, release/11.4.0 8c639945):
F_GETFD/F_SETFD keep the close-on-exec flag per descriptor, F_GETFL
reports the host access mode with the status flags, F_SETFL changes
only O_NONBLOCK, O_APPEND, O_ASYNC, O_FSYNC, O_DIRECT and FRDAHEAD,
F_DUPFD/F_DUPFD_CLOEXEC give the lowest free descriptor at or above the
start through dup (EINVAL for a negative start), F_DUP2FD goes through
dup2, F_RDAHEAD/F_READAHEAD set FRDAHEAD on files (EBADF on pipes,
ENOTTY elsewhere), and unknown commands fail with EINVAL. Status flags
live in a guest table shared by dup, dup2 and F_DUPFD like an open file
description. O_NONBLOCK switches a pipe (PIPE_NOWAIT on Windows, where an
empty read and a full write now report EAGAIN; the host flag on Linux).
Record locks use the host POSIX locks on Linux and throw on Windows.
Changes the host cannot model throw naming the flag and descriptor kind.
Sockets keep their path unchanged.

FreeBSD's printf formats %m as the message for the errno value at the
time of the call. On Linux a format with %m went to glibc, which looks
the number up in Linux's table, so guest errno values above 34 got
another error's text: with errno 35 (EAGAIN) "[%m]" printed
"[Resource deadlock avoided]" instead of "[Resource temporarily
unavailable]", and errno 63 (ENAMETOOLONG) printed "Out of streams
resources". On Windows, and on Linux when the format also had a wide
argument, the guest formatter threw on %m.
FreeBSD 11.4, lib/libc/stdio/vfprintf.c:
saved_errno = errno;
...
case 'm':
cp = strerror(saved_errno);
size = (prec >= 0) ? strnlen(cp, prec) : strlen(cp);
sign = '\0';
break;
The guest formatter now saves errno when it starts and formats %m as a
string with the guest strerror_r text, so width, precision and the -
flag apply as FreeBSD's string path applies them. On Linux a format with
%m goes to the guest formatter like one with a wide argument.

SaveDataDirNameSearchResult.infos points at an array the title reads one
entry per returned directory name, but the search never wrote it, and
SaveDataSearchInfo was declared as 128 opaque bytes. A title that asks for
the infos read whatever its buffer held.
SaveDataSearchInfo is now the 48-byte record shadPS4 declares as
OrbisSaveDataSearchInfo (blocks, free blocks, 32 reserved bytes), and the
search fills one per returned name. Every native save reports
SAVE_DATA_BLOCKS_MAX blocks, as sceSaveDataGetMountInfo and the block sort
keys already assume, so both counts are SAVE_DATA_BLOCKS_MAX and the
reserved bytes are zero.
guest_savedata_search_tests checks the two records, their zero reserved
bytes and that the search writes nothing past them.

A title creating a socket with sceNetSocket sets its options with the BSD

PPSA01289 (Sackboy: A Big Adventure) sets SO_BROADCAST on its UDP P2P

A libSceNet socket is a kernel descriptor on the console, so titles close it
with close(). libSceNet keeps its sockets in its own table, and libkernel's
close passed their numbers to the CRT, which reported an invalid parameter
and left the socket open. libSceNet now registers a closer with libkernel,
as it registers its poller for select. PPSA01289 (Sackboy: A Big Adventure)
closes its P2P socket this way each time it tears its network session down,
leaking one open socket per attempt.

With SO_RCVTIMEO set, Winsock fails a receive that waits that long with
WSAETIMEDOUT, which native_error turned into ETIMEDOUT (60). sceNetRecv,
sceNetRecvfrom and sceNetRecvmsg on a datagram socket therefore failed
with 0x8041013C on Windows, where FreeBSD's sbwait returns EWOULDBLOCK
(35) to soreceive, Linux returns EAGAIN, and POSIX (XSH 2.10.16)
requires EAGAIN or EWOULDBLOCK when no data was received.
A datagram socket has no connection that can time out, so WSAETIMEDOUT
there only means that the receive timeout the guest set has expired:
report EAGAIN. Stream sockets keep ETIMEDOUT, since Winsock leaves a
connection in an indeterminate state after a timeout; TechnicalDebt
records that gap and the one for SO_SNDTIMEO.

fopen opened its stream with _wfopen, which shares read and write
access but not delete access. While the guest held a stream open,
rename of its file failed with EIO and remove with EBUSY. POSIX rename
and remove work on open files, as on Linux and FreeBSD, and since
#3677 the descriptors sceKernelOpen returns share delete access.
fopen now creates the handle with CreateFileW sharing read, write and
delete, with the access and creation disposition of the mode, and
wraps it with _open_osfhandle and _wfdopen, keeping append mode. A
failed CreateFileW sets errno through the error mapping #3677 added to
libkernel's NativeOpen, which moves to libc as
WindowsOpenError_nid_no_patch so that both use it. freopen still
reopens through _wfreopen; TechnicalDebt records it.

PPSA18391 (engine: Clickteam Fusion) reads state_flags & 0x22 != 2 from
sceNgs2VoiceGetState as the end of a sound; each of its sound effects
played once and never again.
The voice now also reports EMPTY (0x20) in that state and keeps
playing, so blocks added later still play. A waveform that was closed
without CONTINUE does not report it.
Resident Evil 4 (PPSA07411, #2776) and PRAGMATA (PPSA02530, #3043) stop
on the absent export with
what(): _ZN3sce4Json14InitParameter225setSpecialFloatFormatTypeENS0_22SpecialFloatFormatTypeE not implemented
Deathloop, Minecraft Legends and Cyberpunk import the base-object
constructor InitParameter2::InitParameter2(), InitParameterRtti2::
setAllocatorRtti and InitParameterRtti::InitParameterRtti(AllocParamRtti*,
void*, unsigned long), which were NotImplemented stubs.
InitParameter2 is the 40-byte object of SharpEmu and KytyPS5: the
allocator, its user data, the file buffer size and the 32-bit special
float format type at 0x18. Both constructors zero it, setAllocatorRtti
writes the allocation parameters and user data where setAllocator writes
the allocator, and setSpecialFloatFormatType stores the type.
InitParameterRtti's constructor writes its three arguments to the first
24 bytes. The NID WVZBP4IyM+E recomputes from the mangled name and is in
the aerolib database. The enum's values are unknown, so no value is
rejected; the inferred layouts are recorded in TechnicalDebt.

sceContentExportStart hands out positive session ids, at most 10 live
(SharpProspero MaxExecution), and sceContentExportFinish closes them.
sceContentExportGetProgress, sceContentExportCancel and
sceContentExportFromDataWithThumbnail take their Orbital signatures and
check the session. The host has no media library to export into, so
FromDataWithThumbnail throws before it calls either data callback, and
GetProgress and Cancel throw for a live session since no export ever
runs and their result for an idle session is unknown. An eleventh Start
and Term with live sessions throw.
Titles: Cult of the Lamb PPSA06465 imports GetProgress, Cancel and
FromDataWithThumbnail (#2686); PPSA21564 (#271) and Cyberpunk 2077
PPSA04029 (#266) import Start.
Sources: Orbital tools/ida/db_types.json (cc408367) for the signatures,
SharpProspero Interop/Content/ContentExport.cs (5dfdb4b0) for the
session model and MaxExecution, shadPS4 content_export.h (443f0224) for
the parameter and callback layouts.

(cherry picked from commit 473d6dd355d2c0ee22f9792927e0e465846569cf)
PPSA07411 (Resident Evil 4) fails to load without these imports. Their signatures are unknown, so they are declared without parameters and throw until they are implemented. Adds a TechnicalDebt entry.

End clears the init flag set by sceVoiceQoSInit and returns 0, so the
library can be initialized again. Before an initialization it returns
0x804E0901 (LIBVOICEQOS_NOT_INIT), as measured on a PS5 (firmware 13.60)
in #1407.
LEGO Horizon Adventures (PPSA14632) calls it at shutdown and Ghost of
Yotei (PPSA26344) calls it on its sceVoiceQoSInit failure branch.
