Directed FLOAT_MODE modes for v_cvt_f16_f32, v_cvt_f16_i16,
v_cvt_f16_u16 and v_ldexp_f16 were ignored, so results stayed
round-to-nearest-even. Hardware uses FLOAT_MODE bits 3:2 (round16);
the directed path runs only when f16 denormals are preserved.

Rosetta runs AVX2, FMA, BMI1/2, F16C and MOVBE, but, unlike an Intel
host, it has neither RDSEED, CLWB nor RDPID. --to-rosetta converts
everything --to-intel does and lowers these three as well:
- RDSEED becomes RDRAND (the /6 form of the same opcode), which also
returns a random value and sets CF.
- CLWB only writes a cache line back, so it becomes a NOP of the same
length.
- RDPID becomes a load of 0 through an optional stub: Rosetta's TSC_AUX
is a constant, not a processor index, so every thread reports
processor 0. A site with no movable instruction after it for the jump
is kept.
The flag implies --to-intel and conflicts with --windows. It is
independent of --macos: it only changes what the conversion produces, so
--macos alone leaves these instructions as they are, as on an Intel Mac,
and a title for Rosetta is relinked with --macos --to-rosetta. Intel
output is unchanged: the target is a parameter of the converter, Intel by
default.
Scalar f16 add/mul/sub ignore FLOAT_MODE denorm16 flush bits on main.
Flush inputs when bit 0 is clear and results when bit 1 is clear at
nearest-even. Multiply checks tininess after 11-bit rounding
(0x387ff000); add/sub use 0x38800000.

Keep WAIT_REG_MEM diagnostic timeouts from completing unsatisfied waits.
Register the existing gated-dispatch capture test with a 1ms diagnostic
timeout and document the missing-producer limitation.
sceSystemServiceParamGetInt always reported English (United States) as
the console language, so a title that follows the console's language,
such as Jelly5 (PPSA99505) with its Arabic text, can only show English.
ANYPS5_LANGUAGE now selects a console language number from 0 to 30
(21 is Arabic). Unset or empty keeps English (United States); any other
value throws at the language query instead of being ignored.
(cherry picked from commit 9bcf196daa01b07a22be876a7f1143149503e054)
AI-assisted: yes. Record that gethostname exposes AnyPS5 rather than the native machine name. Console hostname configuration, sysctl integration and name resolution remain unverified and unimplemented. This one-line note is placed beside an unchanged libc compatibility entry so the branch merges cleanly into tested main 5edae3536.
PPSA11386 calls sceSharePlayInitialize(NULL, 0x1800) at start-up and stops
on any non-zero result, so the console accepts a null heap. The library
keeps no state and does not use the heap; a zero size still throws, as its
error is unknown. libSceSharePlay gets its own CMakeLists for the test.

An NGG passthrough program on the vertex path whose s_barrier only orders wave 0's GS_ALLOC_REQ produced a workgroup OpControlBarrier, which the Vertex execution model does not allow; SPIR-V validation rejected the module at the program's first draw. In a Vertex-stage program the barrier now emits nothing when the program has no LDS or GDS access and no memory write or atomic, so no wave can observe another. With any of those it throws.
A comparison sample with a 2D-array address on a plain 2D color T# takes the emulated comparison, whose runtime modes were only the 2D-array and cube ones. No mode matched, and materialization threw that the image descriptor was incompatible with the static runtime image interface. The emulated comparison now also gets a 2D mode, as the native modes of a 2D-array access already have; the slice is ignored.
The ternary forms share minMaxF16 with v_min_f16 and v_max_f16 and follow
the same rule on gfx1036: a subnormal half input becomes a signed zero when
bit 0 of the f16 denormal field is clear, at IEEE=0 and IEEE=1.

The mutex attribute now keeps its protocol and priority ceiling the way
FreeBSD's libthr does: the ceiling can be set and read only under
PTHREAD_PRIO_PROTECT (EINVAL otherwise), and setting a protocol resets it
to the highest SCHED_RR priority. Mutexes still do not apply priority
protection; that is listed as a silent stub.

A map without MAP_FIXED whose hint lies wholly inside a range still
reserved by sceKernelReserveVirtualRange is placed at the hint, as a fixed
map into the reservation would be. Hints outside reservations and ranges
that are partly mapped keep their hint behaviour. The reservation is
checked under the registry mutation, so it cannot be released and its
address reused between the check and the map (MarcZX100, #2687).

Registration prepares the variants a shader's registered state
predicts; a draw or dispatch whose state needs another one threw
"prepared shader artifact is missing for the requested static ABI".
Titles that link their own libSceAgc build that state themselves and
never call the driver's static ABI resolution, so their draws differ
from the registered prediction. The missing artifact is now prepared at use, logged, and kept
with the snapshot like the deferred and null pixel cases. SourceHandleFor
now checks that the request refers to the registered code, as
InvocationFor already did.
Uncharted: Legacy of Thieves Collection (PPSA05684) still misses on
main 197ffac9 (after the fixed push slots of #2661) for its own pixel
shaders: "prepared shader artifact is missing for the requested static
ABI: address=85899411712 stage=5 wave=64 pushOffset=128
pushCapacity=128".
sceVoiceSetMuteFlag was NotImplemented with an unknown signature and
sceVoiceGetMuteFlag was not exported. Signatures follow shadPS4's
voice.h: a port id and a bool, and for sceVoiceGetMuteFlag a port id
and a bool pointer. The flag is stored per port like the volume; an
unknown port throws and a null output pointer is an invalid argument.
Uncharted: Legacy of Thieves Collection (PPSA05684) imports
sceVoiceGetMuteFlag (Pc4z1QjForU), so on main it stops at startup with
"undefined symbol: Pc4z1QjForU".
sceAvPlayerAddSource queues an auto start for a player created with auto
start or without an event callback. When the title enabled its streams
and called sceAvPlayerStart before the controller thread ran it, the auto
start called Start again on the playing player, which stopped it, released
every video buffer, including the frame the title held, and started the
film over. guest_avplayer occasionally caught this as "video frame is not
a texture allocation"; right after the test's own start, 8 texture
buffers were released in 15 of 15 runs.
The auto start now starts the player only while it is still ready, and
checks that under the player lock together with the start.
TestAutoStartKeepsStartedPlayback starts a callback-less player itself and
checks that no texture buffer is released afterwards and that the frame
it holds stays allocated. It fails on every run without the fix.
RDNA2 min/max flush half inputs to signed zero when input
preservation is disabled, while output flushing alone keeps them.
Apply this to the measured binary forms and pin the hardware rows.
