1 for either infinity like __isinff.

PokeMMO Prospero (PPSA98001) stops at siglongjmp (pebqbE5ws8s) from
libkernel. The title links its own FreeBSD sigsetjmp, so siglongjmp
follows FreeBSD's amd64 __siglongjmp and its sigjmp_buf layout: when the
save-mask flag at offset 88 is set it restores the mask saved at 72
through _sigprocmask, then reloads rbx, rsp, rbp, r12-r15 and the x87
control word and returns to the saved address with val, or 1 for 0.

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.

With graphics pipeline libraries a draw places the pixel shader's push
constants at the fixed fragment slot (Graphics::StagePushOffset) and the
draw cache records that offset, but lookupDraw still expected the stacked
offset after the vertex shader's push bytes. Every pixel stage then missed
as a layout mismatch, so no cached draw or draw recipe was reused and each
draw was captured and materialized again.

FreeBSD's unlink ignores the file's own permission bits, so it succeeds
on a file the guest made read-only with chmod(0400). On Windows the guest
chmod sets the read-only attribute and _wunlink then failed with EACCES,
which sceKernelUnlink and unlink reported. When the path is a regular file
without write permission, make it writable before the single _wunlink and
restore the read-only attribute if the unlink fails, as remove() does
since #2342.

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).

Unity reuses the memory of transient render targets: in FPV Simulator
(PPSA10698) an RGBA8 1920x1080 color texture is sampled at the address
that a D32S8 surface's stencil plane occupied earlier. The lookup found
the stencil plane and threw "sampling the stencil plane ... is not
implemented", which ended the presentation.
9d65003c made depth-plane views in a format that cannot hold the plane
fall through to the ordinary texture path. A stencil-plane view whose
texels are not one byte wide cannot hold the 8-bit stencil plane
either, so it now falls through the same way.

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".
CB_COLOR_INFO COMP_SWAP 1 (SWAP_ALT) on a two-channel format stores the
x and w exports in its two channels (Mesa si_translate_colorswap,
"X__Y"). COLOR_8_8 UNORM and SNORM targets with it bind as R8G8 with
export mapping 0xec; blending into them still throws, since Vulkan
would apply alpha factors to the wrong channel.
Uncharted: Legacy of Thieves Collection (PPSA05684) stopped in its
first level with "unsupported color format 3 number type 0 component
swap 1".
The specialization pass turned OpCompositeConstruct of extracts from one
composite into OpVectorShuffle without checking the types. When the
source is a struct (the {uint, uint} pairs of extended multiplies and
phis of them), the result is invalid SPIR-V ("The type of Vector 1 must
be a vector type"), which the NVIDIA driver (615.71.09) crashes on in
vkCreateGraphicsPipelines instead of rejecting. The fold now requires
both the source and the result to be vector types; a test builds the
struct and vector cases by hand.
Uncharted: Legacy of Thieves Collection (PPSA05684) crashed in the
driver's SPIR-V compiler right after loading its first level.
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.
The Linux patcher writes its own PT_PHDR and PT_INTERP but also copied
the input's. glibc takes the load bias from the last PT_PHDR, which was
the input's entry with the pre-relink address, so such an executable
crashed at start. Both copies also took program header slots, so an
input with PT_PHDR and PT_INTERP and no spare slots failed to relink.
The MinGW CRT delivers argv to main as ANSI code page bytes, and every narrow string became a filesystem path through the same code page, so a game in a directory with characters outside the code page failed to open (#2692). Read the command line as Unicode (wmain via -municode), keep paths as UTF-8 strings, convert at the filesystem boundaries through Io::NativePath and Io::Utf8Path, and run the --autorun output through CreateProcessW.

The background link-time-optimized link used the Pipeline's own layout, which ~Pipeline destroys right after marking the slot released, and ClearCachedPipelines destroys the cached pipelines before ClearPipelineLibraries waits for pending links. A link already past the released check then created its pipeline with a destroyed VkPipelineLayout. On Intel's Windows driver (Arrow Lake iGPU, 32.0.101.8991) agc_driver_vertex_fetch, agc_driver_pixel_interlock and agc_driver_mesh faulted inside igc-default64.dll every run, and agc_driver_prepared_exports and agc_driver_pixel_barycentric_emulation intermittently; all passed with APS5_NO_PIPELINE_LTO=1. The library store's layout, made from the same create info and used for the libraries, lives until ClearPipelineLibraries has waited for the pending links.
