ProsperoRadio (PPSA99001) imports six sceOpusCeltDec functions from
libSceOpusCeltDec and fails to load because no such module exists. It
opens this decoder only as a fallback when libSceOpusDec reports a
retryable error for a CELT packet, which libSceOpusDec here never
returns, so the module is exported without an implementation and each
function throws if it is called, as for sceSaveDataCancel.

Measured on RDNA2 (gfx1035) in review:
- the shared and private apertures are 4 GB windows (the gfx9+ layout of kfd_flat_memory.c), so a flat
address routes by its whole high dword, 0x80000000 or 0x70000000, not by its top 16 bits;
- a dword or short access whose last byte is past the end of LDS reads 0 or writes nothing as a whole;
multi-dword accesses are checked per dword.
The aperture test gets rows that straddle and pass the end of LDS; the TechnicalDebt line names the
public source of the layout and keeps only the PS5's base values as inferred.

Sub-dword stores and unaligned dword accesses go byte-wise; 32- and 64-bit FLAT atomics
route to LDS (64-bit under the workgroup lock), scratch (read-modify-write) or BDA.
agc_driver_flat_apertures covers them in 121 rows, with mixed-address waves and wave64.
The aperture bases and the unmodelled operands 235-238 are listed as inferred.

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.

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.
