UFC 6 (PPSA23566) imports sceNetResolverAbort (#992, #1502); Palworld
(PPSA23126) and LEGO Horizon Adventures (PPSA14632) import
sceNetResolverStartNtoaMultipleRecords.
Signatures and behaviour follow shadPS4 811bfcd7d17e
(src/core/libraries/net/net.cpp, net_resolver.cpp); the abort signature
also matches SharpProspero Interop/Net/Socket.cs.
sceNetResolverStartNtoaMultipleRecords shares the lookup of the Ex form
and, like it, throws for any flag. sceNetResolverAbort returns EBADF for
an unknown resolver and throws for flag bits other than NTOA (1) and
ATON (2) preservation. Host lookups cannot be interrupted, so an abort
during a running lookup makes it fail with EINTR when the host call
returns, without writing its output; with nothing running, the
preservation flags make the next lookup of that kind fail with EINTR.

APS5_TRACE_FRAMES=<start>:<count> (or APS5_TRACE_SECONDS=<start>:<length>)
records every PerformanceTimer scope and stage of the queue workers and the
presenter inside the window as complete events, named after their frame
timing keys, into a preallocated buffer per thread. Slices under 20 us are
counted per thread instead of written; a full buffer stops that thread and
sets trace_dropped. When the window closes, a ProfileOutput writer thread
writes aps5-trace-<commit>-<pid>.json.gz and appends one line to
aps5-summary.jsonl. Without either switch a PerformanceTimer costs one more
predictable branch.

tools/progress_history.py measures the first-parent history of main with
the rules of tools/progress.py, one point per day, and writes history.json,
history.svg and history.html. The Progress workflow runs it after
progress.py; the README shows the chart under the map and links the page.
Labels and points compact as days accumulate.

APS5_SAMPLE_WORKER=<file> now also writes <file stem>.collapsed.txt: one
"frame;...;frame count" line per distinct stack of queue worker 0, root
first, frames as module+0xRVA, which speedscope.app and flamegraph.pl
open. Walks go up to 64 frames, and nothing allocates while the worker is
suspended.
The libraries are built with -fno-asynchronous-unwind-tables, so most of
their functions have no .pdata entry, only a DWARF record in .ehfram, and a
walk ended at the first such frame. The worker's walk now steps those
frames through their record, with the CIE/FDE decoding and the call frame
instructions of libc's unwinder, which move from Unwind.cpp into its
header unchanged. A module is indexed after the worker resumes, the first
time a walk meets it, and every register the step restores is read inside
the worker's stack. The process sampler (APS5_SAMPLE_THREADS) keeps its 12
frames through .pdata.

UFC 6 (PPSA23566) imports both. Initialization marks the library
initialized and termination clears it, as in shadPS4. Termination
without initialization and a second initialization throw, since no
PS5 source settles their results.

(cherry picked from commit d2866a886a7702cdaad56d161460a3ce86ede629)
Export getopt (VUtibKJCt1o) and getopt_long (8VVXJxB5nlk) from
libSceLibcInternal together with the guest variables optind
(zCnSJWp-Qj8), optarg (zG0BNJOZdm4), opterr (yaFXXViLWPw), optopt
(FwzVaZ8Vnus) and optreset (CZNm+oNmB-I). The NIDs were computed with
tools/nid_names.py and all seven are in aerolib; the PS5 payload SDK
f5d40f02 lists the functions and the five objects in
sce_stubs/libSceLibcInternal.c.
Titles (predicted stops from registry order, not observed runs):
- XPSemu PPSA97358, after execv/execve, the signal waits, the
credential setters, mlockall and tcsendbreak:
"FAIL: unresolved ELF import VUtibKJCt1o from libSceLibcInternal.prx"
(getopt idx 204, 10 call sites from 0xF6C23D), then optind (207),
optreset (208), optarg (209).
- RetroArch PPSA99169: getopt_long (idx 554, call sites 0xD2FC0C,
0xD3002A), optind (553), optarg (555).
Behaviour follows FreeBSD release/11.4.0 8c639945: getopt is
lib/libc/stdlib/getopt.c (no permutation, GNU "::" optional argument,
lone "-" as an option when listed), getopt_long is getopt_internal
from lib/libc/stdlib/getopt_long.c with GNU_COMPATIBLE (permutation,
POSIXLY_CORRECT read through the guest getenv on the first call and on
optreset, "+" and "-" prefixes, "W;", optind 0 as a reset, abbreviation
and ambiguity rules and the GNU warning texts). Warnings are written to
the guest stderr stream as "<__progname>: <message>", as warnx does.
The struct option layout and argument kinds are include/getopt.h.
The code lives in libSceLibcInternal because __progname is a libkernel
export that libc cannot link.
A null getopt option string, a null argument vector or argument, a
negative optind and an optind moved inside a pending permutation throw
where FreeBSD faults. getopt_long_only is not exported.
guest_getopt runs the FreeBSD getopt_test cases (contrib/netbsd-tests
t_getopt.sh with the h_getopt and h_getopt_long result format) plus
grouped and optional arguments, "--", permutation order, "+" and "-"
prefixes, optreset and optind 0 restarts, POSIXLY_CORRECT, all three
long argument kinds, abbreviations, ambiguity, flag pointers, "W;",
optopt with opterr 0 and the exact stderr text.

(cherry picked from commit a2740166d93920c301e1add23ceea762b4acad27)
The title-module variants of sceKernelGetModuleList and
sceKernelGetModuleInfo, following shadPS4: the list leaves out system
libraries and the info call answers EPERM for one. A system library is
a loaded .prx image that is not a relinked title module.
NHL 27 (PPSA34063) imports both and fails to load without them.

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.
