On Windows every unwind step called VirtualQuery to find the frame's
module, and a module with a plain .eh_frame (libstdc++, libgcc, libwinpthread)
was searched by decoding each FDE in turn. A C++ exception crossing those
frames cost about a millisecond. Look the module up with RtlPcToFileHeader
first, falling back to VirtualQuery for images the loader does not know,
and binary-search a per-module index of FDE start addresses built on first
use.
A 1D sample or load of a 2D T# had no runtime image mode after the mode table landed, so it was still refused at materialization. Sampled 1D accesses now also accept a 2D view; the address completion in the emitter reads the missing row as 0.
Measured on hardware: a position component the instruction omits reads as 0, like an explicit 0, and the next VGPR is ignored. Missing array layers and derivative components are 0 too. Cube coordinates still need all components.
Multi-level views, and views starting above mip 0, are bound as their base
level only when every use of the image is image_sample_lz through an
unnormalized S# without minimum LOD or LOD bias, the case measured exact on
RDNA2. Selected-LOD, implicit-LOD and offset uses keep throwing.
The recompiler records selected-LOD uses (SamplerUseNonZeroLod) and proves
the case per image (imageUnnormalizedBaseLevel); the shader disk cache
format goes to 27.

Vulkan only accepts unnormalized samplers on single-level views, while the
guest binds full mip chains and samples their base level. Bind a lazily
created one-level view of the descriptor's base mip instead of refusing
mipmapped views and views that start above mip 0.
Forwards _sceUltWaitingQueueResourcePoolCreate and _sceUltSemaphoreCreate to the existing calls, like the other underscore Ult exports. Declares sceNetShowIfconfig, sceNpWebApi2GetMemoryPoolStats, Json::Value::setNullAccessCallBack, kqueue, kevent and one pad call of unknown name without an implementation.

Map red and blue exports, write masks and constant-color blend factors together. Reject conflicting simultaneous target constants.
Semantics: Mesa 26.2.2 src/amd/common/ac_formats.c ac_translate_colorswap; console equivalence remains unverified. Graphics tests passed. Written with AI assistance.
Allocate cached sets without individual-free pools. Reset a pool after its
last owner releases it. Keep stable pool indices, skip full pools, and
terminate if reset fails. No GPU wait is added.
This avoids RADV 26.2.2's affected individual-free allocation path.
Validation: Fedora 44 Release graphics tests pass. The reset-failure
regression fails on the previous behavior and passes on this change.
llvmpipe and RX 6600 pass the 3,301-set lifecycle test with core and
synchronization validation. Windows was not tested.
AI-assisted: yes.
Add an optional input helper for test runs without desktop input injection. Preserve physical input and release injected buttons automatically.
Validation: guest_pad tests and Python helper CLI smoke checks passed. Written with AI assistance.
Drops the stale pending-dependency note (#553#683#684#685 are merged), adds the
package source and the Linux, extended-gameplay, save/load and audio results
reported in the thread, and replaces the cold-start note with the measured cause.
The UCRT diagnostic note is removed: no report on current main.

Add standard quiet NaN generators nanf (DZU+K1wozGI) and nan (zck+6bVj5pA) to libc.
Resolves startup failure in VLC for PS5 (PPSA85300) where execution halts at nanf on Linux once strsep is available.
PPSA21703's Unity PSN plugin imports sceNpWebApi2GetMemoryPoolStats
(Xweb+naPZ8Y), so the title did not start.
sceNpWebApi2Initialize now records the pool size of each context and
sceNpWebApi2Terminate forgets it. The statistics report that size with
no peak or current use, as sceHttp2GetMemoryPoolStats does, since nothing
is allocated from the pool. A null output or an unknown context throws.
The signature and layout follow the Http2 statistics and are recorded in
TechnicalDebt.
The library gets its own CMakeLists.txt, equivalent to the generic rule,
to register its test.
