Route oversized compute LDS through a per-workgroup storage buffer.
Retain native shared memory for programs that fit the device limit.
Carry the spill stride through prepared shader results and dispatches.
Preserve the stride in the full-result codec and its round-trip fixture.
Keep the Linux RecompileResult size guard aligned with the added field.
Exercise interleaved workgroups and the device-limit boundary.
This topic contains only the LDS change and its reviewer-requested repair.
The base includes upstream's separately merged NaN result correction.
VOP2 0x06 measured the same as VOP3 0x140 on gfx1010 (RX 5700 XT) in
wave32 and wave64, IEEE 0 and 1 and f32 denormal modes 0 to 3: the
product is rounded before the add, f32 denormal sources, product and
result are flushed in every mode, and a zero factor gives a +0 product.
It now shares the v_mad_legacy_f32 translation with the accumulator as
the addend, and f32DenormalFlushFor returns 3 for it as well. A new
execution test pins the measured results of its VOP2 and VOP3 forms.

The guest_interfaces test now follows guest_thread_callback_abi instead of guest_errors, and the TechnicalDebt entry follows the libc SSE4a trap emulation entry instead of ending the Functional list, where other open pull requests add theirs.
A formatted buffer load or store through a GPU-selected descriptor still
emitted the switch over every buffer format inline, at each access. A
Ghost of Yotei compute pass with ~300 such accesses compiled to 37M SPIR-V
words, and its pipeline took 40 s or more to create.
The switch is now emitted once per component count, direction, d16,
coherence, kind and stop mode, as a SPIR-V function that takes the
descriptor fields, the offsets and the access's PC. When faults stop the
invocation, the helper returns whether one did and the caller stops there.
BDA faults record the PC from BdaInstructionPc, the access's own PC or the
one a shared helper takes.

The --deferred-undecodable mode registers shaders through a Vulkan
device but, unlike --deferred, did not check for one first. On the
Windows CI runner, which has no Vulkan driver, vkCreateInstance returns
VK_ERROR_INCOMPATIBLE_DRIVER and the test fails instead of skipping, so
the windows job on main has failed since e5b32bb4. It now returns
VulkanTestSkipped like the other modes.
CB_BLENDn_CONTROL factors 15-18 (BLEND_SRC1_COLOR, BLEND_INV_SRC1_COLOR,
BLEND_SRC1_ALPHA, BLEND_INV_SRC1_ALPHA) threw "unsupported blend
factor". They blend MRT0 with the pixel shader's MRT1 export as the
second source, as RADV and radeonsi program it.
DecodeState maps them to the VK_BLEND_FACTOR_SRC1_* factors and accepts
them only with pixel exports to slots 0 and 1, color writes to slot 0
alone, an MRT1 export with MRT0's export format and shader mask, an
ADD, SUBTRACT or REVERSE_SUBTRACT operation and an identity component
order. The blend is draw state, so the specialized module of the
registered pixel shader moves its MRT1 output to location 0 index 1,
which ValidateShaders requires; pipelines need dualSrcBlend, now enabled
when present. The request field dualSourceBlend is in the module key,
the result memo, the draw key and the serialized request (version 15).
Drop IFF_POINTOPOINT from an address without a peer and compute an IPv4 broadcast address the host omits from the netmask, since FreeBSD always provides the address when the flag is set. Check zero port, flowinfo and padding in the test.
Return -1 with the FreeBSD errno for a null list and for expected host and allocation failures, as getcwd does. On Windows, give an unspecified prefix length a host mask, leave PPP and tunnel adapters without broadcast or point-to-point flags since their peer address is not reported, fall back to if<index> for long NDIS names, and bound the adapter query retries. Compare every entry with the host's own list in the test.
List the host's IPv4 and IPv6 addresses in FreeBSD's struct ifaddrs layout, with FreeBSD sockaddrs and interface flags, from getifaddrs on Linux and GetAdaptersAddresses on Windows. The list is one allocation, so freeifaddrs is a single free.
Move the image unregistration out of the Module destructor into
dlclose_nid_postfix. It runs while the handle is still registered, so a
failure (the image stays leased by GPU work) propagates to the caller and
leaves the module loaded and usable. Images shared by another open
handle stay registered until the last handle closes.
guest_memory now checks that dlclose under a held lease throws and keeps
the module, its symbols and its protection.

A .guest.prx image registered by sceKernelMprotect stayed in the guest
allocation registry after dlclose freed it, so its dead ranges blocked
later mappings at that address and could reach GPU builds.
The Windows module destructor now unregisters the image before
FreeLibrary. Unregistering waits for outstanding leases on the image like
unmap and protect do; if the wait fails the module stays loaded.

On Windows, sceKernelMprotect accepted only the executable's image and threw
"Memory protection of a foreign image is not supported" for every other
image. Bundled title modules are relinked into DLLs named <module>.guest.prx,
so a title that reprotects its own module pages failed. Dying Light 2's
bundled libNRD does this at start-up (#1794).
DoMprotect now also accepts images whose file name ends in .guest.prx, and
registers their committed pages like the executable's. Other images are
still refused.

On Windows, sceKernelPread and sceKernelPwrite called the POSIX pread and
pwrite wrappers, which throw on every failure, so a bad descriptor, a
negative offset or a write to a read-only descriptor aborted the process
instead of returning an error as the Linux build does. ftruncate and
sceKernelFtruncate threw on any host failure on both platforms.
Give the Windows sceKernelPread and sceKernelPwrite the same checks and
SceErrorFromErrno returns as the Linux ones, and accept a zero-length
transfer with a null buffer. Report a positioned transfer on a handle
opened without the needed access as EBADF instead of EIO. Return EINVAL
from ftruncate for a negative length and for a descriptor opened without
write access, as FreeBSD does, and pass other host errors to the guest.
Fixes#2423
Generate guest PRX dependencies with adjacent and separated repeats, equal names at distinct string offsets, and invalid-name controls. Check acceptance for Linux and Windows conversion and first-seen dependency order in ELF outputs.
