lstat and readlink threw NotImplemented for every Windows reparse point
other than a symbolic link or a drive junction. A tag without the name
surrogate bit (cloud files, deduplication) does not stand for another path,
so lstat now answers as stat does and readlink returns EINVAL, as FreeBSD
does for a file that is not a link and as CPython's os.lstat and os.readlink
do (bpo-37834). A name surrogate that is neither a symbolic link nor a
junction (a mounted volume, a WSL link) is reported as the reparse point
itself with the mode of its attributes, and readlink returns EINVAL.
The tests set reparse tags with FSCTL_SET_REPARSE_POINT, one without the
name surrogate bit and one with it. A compact /exe (WOF) file cannot serve
as the fixture: on Windows 11 24H2 the WOF filter hides the reparse point
from GetFileAttributesW and FileAttributeTagInfo alike. Windows refuses
every open of an unhandled tag without FILE_FLAG_OPEN_REPARSE_POINT, so the
test requires lstat to agree with stat rather than to succeed.
mashingaan's boykopovar/AnyPS5#6447 returned EINVAL for other reparse
points without the tag check.

When the graph is built without the wave size and the return address
escapes under only one of wave32 and wave64, the graph records that size
and its error instead of throwing, and translation throws it only at
that size. A wave64 program that reads a compare mask written over a
call's link pair from a scalar instruction is now recompiled, while the
same program at wave32, where the high dword still holds the return
address, is refused.

The raw-byte check that runs before a syscall pattern between PS4 unwind
functions is skipped now also accepts mov rax, imm64, merges a following
mov al, imm8 or mov ax, imm16 into the earlier constant, and walks back
over any number of register moves or zeroings that leave rax alone
instead of at most seven. Visited states keep the walk linear in the
bytes it covers.

resource-lookup-changed skipped with its own texts when the device has no
host imports or refuses the import of the watched surface. Neither matches
DEVICE_LIMITATION in tools/check_skips.py, so a runner without host imports
would fail the job instead of recording a device skip. Both now print the
existing "skipped, host imports are unavailable".
The control-flow builder does not know the wave size (the front end is
shared across wave sizes), and with an unknown size it took a v_cndmask
mask to read two registers but a VOPC result to write only one. A wave64
compare that overwrote a call's link pair before a v_cndmask read it was
then rejected as a link register escaping the call/return model. The
check now runs once for wave32 and once for wave64 when the size is
unknown, so each read is matched with writes of the same width.

FreeBSD 11.4 vfs_cache_lookup answers ENOTDIR when the directory it searches
is not a directory (sys/kern/vfs_cache.c:2104-2105), the lookup behind the
calls fixed in the earlier ENOTDIR changes. These four calls answered ENOENT
for a path such as file/child on Windows.

A color view of one slice of a 2D array target refreshed the whole array
image before each draw, sampled lookup and present. When the array's unused
slices lie over other live targets (ps5-opengl declares every target as a
two-slice array and allocates the next one over its second slice), each
refresh stored the other targets' pending results, wrote back its own and
uploaded the whole image from guest memory again, on every pass.
StorageTexture::RefreshLayers refreshes the tracked layers that hold the
given array layers alone: it flushes and compares their memory only, and
results of other images pending over the other layers stay pending. A layer
outside the range whose memory changed or that holds another image's pending
results is left behind; GenerationFor reports it as never current, so a use
over it takes the whole Refresh. It falls back to Refresh for volumes,
single-layer and DCC images, an alias, or results of the image pending
outside the range.
A draw into an array slice, a 2D view of one layer of an array image and a
present of one layer use it. The compare memo of untracked memory is kept
per range, so a layer refresh's compare is memoized like the whole image's.

A voice callback runs during its system's render. A rack or system
destroyed from that callback was freed while the render still walked
it, which corrupted the heap. sceNgs2RackDestroy and
sceNgs2SystemDestroy now throw when the calling thread is rendering
that system; the console's behaviour there is not measured.

Follow-up to #7652. A raise on a thread running host code waited up to the
1 s RetryLimit before falling back, so Windows guest_raise_exception (about
220 host-resident raises) went from ~15 s to 17-30 s. Host code now has its
own HostCodeLimit of 50 ms; RetryLimit still guards NtContinue and winpthreads.
