sceKernelSyncOnAddressWait parks the calling thread while the 32-bit word
at the address still holds the expected value, until
sceKernelSyncOnAddressWake releases it or the timeout expires.
sceKernelSyncOnAddressWake releases up to the requested number of threads
parked on the address, in arrival order.
The libc.prx bundled with SDK 9 titles imports both for its once
primitive, so those titles stopped at load with an unresolved import.
# Conflicts:
# docs/dev/TechnicalDebt.md
libkernel did not export sceKernelMapNamedFlexibleMemoryInternal, which
the libc bundled with SDK 9 titles imports. It now forwards to
sceKernelMapNamedFlexibleMemory: the mapping counts against the flexible
budget, gets the range name and is released by sceKernelMunmap. Older
libc builds call the public function at the same sites with the same
arguments and result handling.
The known callers pass flag 0x8000, whose meaning is unknown. It is
still rejected as an unsupported mapping flag and is recorded in
TechnicalDebt.

scePngEncQueryMemorySize, scePngEncCreate, scePngEncEncode and
scePngEncDelete encode R8G8B8A8 and B8G8R8A8 images with a pitch into
RGB or RGBA PNGs using the shared encoder in core/Decoder/Png.
Decoder::Png::Encode takes optional compression level and filter
options so the encode parameters are honoured.

All six exports are implemented: MP3 and AAC (ADTS or raw blocks) are
decoded with the bundled FFmpeg and ATRAC9 with LibAtrac9, one unit per
call, into interleaved S16 or float PCM, with the libSceAudiodec
validation and error codes. libSceAudiodec.native is built from the same
sources.

Sign-in, web browser and player dialogs finish cancelled; the message dialog finishes at once;
NpAuth, entitlement consumption, reachability, account age and the NpUtility bandwidth test
report signed out; sceKernelMtypeprotect changes the protection (the memory type has no host
equivalent); the APR ForEach resolvers resolve every path and report each failure in its own
result entry. vswprintf's stub is dropped in favor of the existing wide-formatter
implementation, which already covers it on every platform.

Keyboard input follows libSceMouse: the video out event loop forwards SDL
key and focus events, whose scancodes are USB HID usages, and the library
keeps the pressed keys, modifiers and lock LEDs in a 16-entry history for
sceKeyboardRead and a snapshot for sceKeyboardReadState.
sceKeyboardGetKey2Char translates the 101-key arrangement; the 106-key
one throws and is listed as technical debt.
KeyboardData holds 16 key codes (96 bytes), not 6.

sceSslGetCaCerts reports that no CA certificates are available and
sceSslFreeCaCerts clears the structure, in line with the library's
no-network behaviour. sceHttp2AbortRequest succeeds like
sceHttpAbortRequest. sceSslClose and sceSslGetSerialNumber keep throwing
and are listed as unknown signatures.

In 64-bit mode a REX prefix only takes effect when it immediately
precedes the opcode; a REX followed by a legacy prefix or another REX is
ignored. The instruction decoder, the rewriter's reference classifier,
DecodedInstruction and the SSE4a, SHA-256 and CLZERO operand decoders
read legacy prefixes and then at most one REX. `48 F3 0F 2B 00`
(MOVNTSS) was therefore scanned as `[48 F3][0F 2B 00]` and kept, and
`48 67 0F 01 FC` lost its address-size prefix.
All of them now accept REX bytes among the prefixes and keep only one
that directly precedes the opcode. The converter's guard against
prefix-only fragments is removed, since the decoder no longer produces
them, and the TechnicalDebt entry describing the split is dropped.

Lower CLZERO out of line instead of failing the relink: the 64-byte line
containing rAX (EAX with 67h) is cleared with four MOVNTDQ stores of
zero, the same non-temporal, weakly ordered store. The line address is
masked in xmm0 so RFLAGS stays untouched; xmm0 and rcx are spilled below
the red zone. Short sites share stubs through MatchSequence. CLZERO with
LOCK, an FS/GS override, a 66/F2/F3 prefix or longer than 15 bytes fails
the relink.
The decoder splits a REX followed by another prefix into a separate
instruction, which would hide a prefix that changes what CLZERO or the
next instruction does. The converter now fails the relink when such a
prefix-only fragment directly precedes an AMD-only instruction or would
be moved into a stub as a trailing instruction.

Replace MONITORX with a NOP and MWAITX with PAUSE in place, padded with
NOPs to the original length, instead of failing the relink. MWAITX may
return before its timer or a store to the monitored line, and without an
armed monitor it does not wait, so callers already re-check their
condition; the replacement takes that path every time.

Lower SHA256RNDS2, SHA256MSG1 and SHA256MSG2 (register forms) out of line
with legacy SSE2 instructions only, so relinked code no longer needs
SHA-NI. Consecutive short SHA-256 and SSE4a sites share one stub. The
SSE4a stub builder moves to StubBodyBuilder for reuse; IsShaNi now also
recognises SHA256RNDS2 (0F 38 CB). Memory operand forms fail the relink.

feat: export the AMPR command buffer waits and writes, sceAgcFuseShaderHalves, sceAgcSetSubmitMode, sceNpSessionSignalingCreateContext and sceNetEpollAbort
Lower INSERTQ xmm1, xmm2 (F2 0F 79) out of line with SSE2 only instead of
failing the --to-intel relink. Length and index are read from bits 69:64
and 77:72 of the source; dst[127:64] is zeroed as on hardware.

feat(relinker): lower register-form EXTRQ and relocate following instructions for short sites
- **Lowering:** register-form EXTRQ is emitted out of line with SSE2 only. Two scratch XMM registers (distinct from both operands) are spilled; one gets the index (`src >> 8 & 63`), the other `(64 - length) & 63` (`length` masked to 6 bits, so 0 means 64). The destination is shifted right by the index, then left and right by the complement, which keeps the low `length` bits. INSERTQ register form is still reported as unsupported.
- **Short sites:** when a site is shorter than a `jmp rel32`, the converter extends it over the instructions that follow it until it's 5 bytes long:
- following EXTRQ/INSERTQ instructions (before any other instruction) are lowered into the same stub, via a new `MatchSequence`;
- other instructions are copied after the lowered body (`LowerOutOfLine`'s new `trailing` bytes), but only if they're sequential, have no RIP-relative operand and no branch target;
- anything else (a return, a branch, RIP-relative code, the segment ending) still fails the relink, as does a branch target inside the extended site.
- `docs/TechnicalDebt.md` now lists only the INSERTQ register form, MONITORX/MWAITX/CLZERO/RDPRU/MCOMMIT and SHA-NI.
Brings in main up to 9958d26 (homebrew runtime, POSIX wrappers in
libkernel, sce_module guest modules and --skip-sce-module, the --to-intel
general pipeline, libSceRandom, libSceRtc, libScePosixForWebKit,
libRenoirCore, test wiring).
Resolutions where both sides implemented the same thing:
- libkernel pthread: main's structure (lazy static initialisation,
destroyed markers, MutexOperations/CondOperations, mutex protocol and
condattr clock) with this branch's TimedWait deadlines and condition
(precise timed lock/wait on Windows), wait tracing, the adaptive mutex
type 4, POSIX default ERRORCHECK mutexes, EDEADLK/EPERM results instead
of throws, and condition clocks honoured for absolute timeouts.
- libc locale: the guest Dinkumware ABI (_Locimp, facet vtables, short
ctype/case tables, locale ids, stream storage) is kept because guest code
inlines those layouts; main's C character functions are kept on top.
- libc stdio/strings/math: main's stream functions (guest FILE status
sync), strerror/perror, remove, formatting, string and math exports win
over this branch's duplicates.
- libc paths: main's working directory with this branch's path aliases
resolved on the normalised guest path.
- libkernel file: this branch's sceKernel* results as SCE errors, main's
POSIX wrappers and both fstat helpers.
- relinker: this branch's stub lowering keeps its trampolines through the
main executable path; guest modules refuse lowerings that need stubs.
- AGC driver: main's rendering wait is executed by this branch's workers.

Maintainer noted the opt-in-via-documented-flag SPIR-V validation gap
isn't the silent-stub category this doc tracks; the README correction
stands on its own.

EXTRQ, INSERTQ, MOVNTSS and MOVNTSD are rewritten at relink time: same-length in-place forms
where they exist, otherwise a jmp rel32 into an appended executable section holding a
scratch-free SSE body and a jump back, so no code shifts and no RIP-relative or jump-table
operand needs adjusting. Decoder fixes for POPCNT and 0F BB (BTC), codegen and elfpatcher
tests, README and technical-debt notes. The runtime illegal-instruction trap stays as a
fallback.

README stated SPIR-V is "successfully produces validated via Spirv-Tools"
unconditionally, but ANYPS5_ENABLE_SPIRV_TOOLS defaults OFF and the only
validation call is gated behind it, so this doesn't happen in a default
build. Caveated the README line and added the gap to TechnicalDebt.md's
silent-stubs list. Also fixed a stale line-number citation there (a prior
refactor moved the SpirvTargetOptions assignment block from row 219 to 212).
