A title's executable can name a bundled module differently from the file it
ships: Dying Light 2 needs EOSSDK-PS5-Shipping.debug_prx and ships
EOSSDK-PS5-Shipping.prx. Needed names were matched by exact filename, so the
module was skipped without an error and start-up failed to load it. Renaming
the file does not help either: the title later loads the module at run time
by its shipped name (/app0//EOSSDK-PS5-Shipping.prx), and dlopen looks for
that name's .guest.prx (#1794).
When no file has the needed name, a module whose name differs only in its
.prx, .sprx or .debug_prx extension now satisfies it, in the module
directories or elsewhere under the input. The output keeps the shipped file
name, and the needed name is added as another name of that guest module.
Two such candidates for one needed name are ambiguous, as before.

FreeBSD vsyslog logs the complaint with LOG_ERR|LOG_CONS|LOG_PERROR|LOG_PID passed as the priority (0x23), not LOG_ERR.
Co-Authored-By: Claude <[email protected]>
ps5-opengl (PPSA99005) and ProsperoRadio (PPSA99001) import syslog
from libSceLibcInternal. Messages go to stderr with the priority, and
the format follows FreeBSD's vsyslog: %m expansion, masking of unknown
priority bits, LOG_USER as the default facility, errno preserved.

A title's descriptors are taken as never being terminals: a file or
pipe gets ENOTTY with the termios untouched, a socket gets what its
protocol answers a termios ioctl on FreeBSD (EADDRNOTAVAIL for AF_INET,
EOPNOTSUPP otherwise), and a closed or invalid descriptor EBADF.
tcsetattr gives EINVAL for an action other than TCSANOW, TCSADRAIN or
TCSAFLUSH, with or without TCSASOFT, before anything else, and EFAULT
for a null termios before the descriptor is checked; with TCSASOFT a
null termios throws, where FreeBSD's libc faults copying it. What the
console gives a title as descriptors 0 to 2 is unknown, as recorded in
TechnicalDebt.

The guest image reader and the module builder already produce a
platform-neutral GuestImage; --macos adds a third writer next to the ELF
and PE ones. The executable and every bundled module become x86-64 Mach-O
files (modules as dylibs in app0/sce_module) that run under Rosetta on
Apple silicon.
FreeBSD code reaches its thread pointer through %fs, which macOS cannot
set, so the writer rewrites each %fs access into a stub that reads the
image's thread pointer from a pthread key and allocates the TLS block on
a thread's first access. Dynamic TLS goes through the image's descriptor
instead of __tls_get_addr. Imports bind by NID to the prx libraries
beside the output, exports and TLS imports use the dynamic symbol names,
and the image's metadata lives in __APS5DATA,__meta.
--macos conflicts with --windows. The macOS runtime that consumes the
output (TLS allocation, libraries built for macOS) comes in separate
changes.
LibwuIonIBw registers video out event id 16, which the host never triggers because its VRR state does not change; kP2L8t3j-aM returns 0 without effect.
--registry only described the imports of the executable, so a title whose
own modules import system functions (PSN.prx, libc.prx and others) could
not be audited completely. With --registry the relinker now also writes
<output-stem>.<module>.registry.json for every converted guest module.
An entry is written for each relocation against an undefined symbol that
no other bundled module exports, the same test the module builder uses to
decide that a dependency is satisfied by a sibling. Entries carry nid,
library and targetOffset; the symbol name no longer has the # suffix by the
time the module is read, so the NID is the bare 11 characters. The
executable's registry is unchanged.
The test converts two modules where one is provided by its sibling, for
Linux and Windows output, covers the DT_RELA and DT_JMPREL tables, checks
that the same module imports the sibling's function once the sibling is
absent, and that nothing is written without --registry. Registered in
CTest as guest_registry.
Keeps this branch's CONTEXT_FULL | CONTEXT_SEGMENTS read, context-first
order and bounded retry in RaiseOn, and adds #1478's ymm save fields to
both deliveries. The test keeps both phase sets; the vectors phase runs
after the continuing, selfing and looping phases and counts their
deliveries. The TechnicalDebt entry about ymm upper halves is dropped,
since #1478 preserves them.

GuestOfflineImports still expected sceRudpGetStatus to throw not-implemented;
the implementation now returns RUDP_ERROR_NOT_INITIALIZED before init and
zeroes the status buffer after it.
v_dot2_f32_f16 rounded a.x * b.x + a.y * b.y + c once, computed with f64
TwoSums and round-to-odd. GeForce GPUs run f64 at 1/32 or 1/64 of the
f32 rate, which made it cost about 44 v_fma_f32 on an RTX 4060.
The f16 products are exact in f32, and the correctly rounded sum of
three f32 values only needs f32: two TwoSums, a round-to-odd sum of
their errors and a final add (Boldo and Melquiond, "Emulation of FMA and
Correctly Rounded Sums: Proved Algorithms Using Rounding to Odd",
IEEE TC 57(4), 2008), with round-to-odd emulated by stepping an even
rounded sum one ulp toward its error. With finite inputs, c zero or at
least 2^-100 and a result between 2^-100 and 2^127, every value involved
is zero or a multiple of 2^-123, so no driver flush can reach it. Other
inputs, and zero results, take the f64 lowering in a branch.
New test agc_driver_f32_dot2_rounding checks random, cancelling and tie
cases against an exact fixed-point sum, and the NaN, infinity and zero
rules.
Titles that link the release module libScePsml.prx failed to start
because no host library had that name; PPSA25344 links it. libScePsml
and libScePsml_debug are now built from the same source.
scePsmlMfsrGetDispatchMfsrPacket1000, which PPSA25344 imports, is
added without an implementation.

With the 16-bit RoundingModeRTE, DenormPreserve and
SignedZeroInfNanPreserve guarantees, convert each value to the nearest
half with OpFConvert, convert the half back to f32 and, when it is
further from zero than the source, step its bits one toward zero. That is
the toward-zero half for every finite value, including subnormal results
and 65504 for values from 65520 up; infinities and the quiet NaN with
the high payload bits are kept. Other devices keep the integer
conversion.
New test agc_driver_f16_pack_toward_zero checks every half, its f32
neighbours and the midpoints to the next half, with both signs.
The integer emulation of the round-to-nearest-even float-to-half
conversion is exact but costly: a compute shader with about 3600
conversions never finished compiling on NVIDIA. When the device enables
shaderFloat16 and guarantees shaderRoundingModeRTEFloat16,
shaderDenormPreserveFloat16 and shaderSignedZeroInfNanPreserveFloat16,
it advertises Float16, RoundingModeRTE and DenormPreserve, and the
recompiler emits OpFConvert under the 16-bit RoundingModeRTE,
DenormPreserve and SignedZeroInfNanPreserve execution modes instead.
NaNs keep the emulated quiet NaN with the high payload bits. Devices
without these guarantees keep the emulation.
Graphics validation accepts the RoundingModeRTE, DenormPreserve and
SignedZeroInfNanPreserve execution modes for 16-, 32- and 64-bit floats,
so vertex and pixel shaders with a native conversion still draw.
