CONTRIBUTING.md told authors to write `Depends on #N` in the
description, but the pr-template rule in tools/check_conventions.py
only accepts the checklist line `Depends on: #N` or `Depends on: none`
from the pull request template. A pull request that followed the
document failed the Conventions job with "fill Depends on with #N or
none". The sentence now shows the checklist form.

With git's default core.quotePath=true, paths with non-ASCII characters
were printed quoted and octal-escaped. The checker stored the quoted
string as the path and then failed in git show with a traceback. git()
now passes core.quotePath=false so raw UTF-8 paths are used. A test
covers a diff containing a non-ASCII file name.

Authors with no merged pull requests can have 1 open, with at least 1

Titles that import it now load; calling it throws like the other
coredump queries, since host crashes are not turned into guest dumps.

A descriptor dword built by S_BREV_B32, V_BFREV_B32 or S_BREV_B64 from a
constant stayed a runtime value, so the resource could not be resolved
and the shader failed to prepare. The constant folder now reverses the
bits of an immediate the way the hardware does (D[31-i] = S0[i]), like
the existing BitCount32 fold. ConstantBitTest covers the fold.

Waits on eventCondition go through libkernel's TimedWait::Condition (precise
timed waits on Windows) instead of std::condition_variable::wait_for, as
requested in review.
libkernel.prx does not export TimedWait::*, so libSceVideoOut.prx had an
unresolved import and titles stopped at load. Compile TimedWait.cpp into
libSceVideoOut, and use NotifyAll for the notify added on main.
The flip queue's condition variable went through winpthreads, whose
timed waits end on GetTickCount64 steps: the present thread's 10 ms poll
for SDL events and the pad, taken while no flip is queued, ended 11 to
24 ms later on Windows, and WaitForFlipRoom's 60 s bound had the same
granularity. Use TimedWait::Condition, which waits on an event and a
high-resolution timer, so the poll ends at 10 ms and a submitted flip
still wakes the present thread at once.

Use unlocked POSIX EOF/error queries after unlocked byte operations so status synchronization cannot reacquire the stream lock. Keep the verified UCRT status calls on Windows, and cover byte, status, error, and held-lock behavior.

sceKernelGetProcessTime and sceKernelGetProcessTimeCounter measured from
a start captured on their first call, so the first reading was about 0
however long the process had run, and exactly 0 when both reads fell in
one tick of the host clock (100 ns on Windows). Capture the start when
libkernel loads.
Titles that ship their own libc.prx or Unity's PS5Util.prx import
_umtx_op (04AjkP0jO9U) for atomic waits, call_once and futex-style
waits. Implement UMTX_OP_WAIT, UMTX_OP_WAKE, UMTX_OP_WAIT_UINT,
UMTX_OP_WAIT_UINT_PRIVATE and UMTX_OP_WAKE_PRIVATE as FreeBSD 11's
kern_umtx.c does, on the sceKernelSyncOnAddressWait waiter queue.

Two defects found in review of the Linux delivery:
A raise right after scePthreadCreate reached the new thread before
RunThread set currentThread, so scePthreadSelf() in the handler adopted
a second handle, and could deadlock on glibc's thread lock when the
signal interrupted pthread_getattr_np. The creator now blocks all
signals around the std::thread construction, so the child starts with
them blocked, and RunThread restores the creator's mask once the thread
is registered, as libthr does. A raise in that window stays pending and
is delivered just before the entry runs.
A handler that set reserved MXCSR bits made rt_sigreturn fail with
SIGSEGV. The MXCSR the handler leaves is now masked with the frame's
MXCSR_MASK (0xffbf when it reads 0), as FreeBSD's fpusetregs does, on
both platforms; Windows also keeps CONTEXT.MxCsr equal to
FltSave.MxCsr.
guest_raise_exception raises right after each of 50 thread creations and
checks scePthreadSelf() in the handler, and its context round trip sets
a reserved MXCSR bit and FZ and checks that only FZ is kept.

sceKernelRaiseException threw on Linux, so a title whose garbage
collector stops threads with it (Unity's PS5Util raises SIGUSR1 on each
thread and reads mc_rsp from the handler's context) could not run there.
The raise now sends the host SIGUSR1 to the target thread with
pthread_kill. The host handler, installed on first use with SA_SIGINFO
and SA_RESTART, builds the FreeBSD-layout ucontext from the interrupted
registers and the FXSAVE area, calls the guest handler on the target's
own stack and writes the registers back, so the handler's changes reach
the interrupted code, as they do on Windows. errno is left as the
handler leaves it, as libthr does.
A raise on another thread takes the target's join lock with the host
signal blocked and returns ESRCH once the thread has finished, so a
detached thread's pthread_t is never signalled after it exits. The
pthread_t is recorded when the thread is created or adopted. Handlers
are now lock-free atomics, as the host handler reads them.
guest_raise_exception now runs on every platform. It also checks that
r13 and xmm8 reach the handler and that r12 and xmm8 written by the
handler reach the interrupted code.

Comparison sampling of a color texture required the view's X channel to select red. A title runs image_sample_c_lz on a 1x1 R8 unorm placeholder whose dst_sel is constant 0 on all four channels.
On hardware the compare result is placed in every channel and each returned channel then applies its own dst_sel: 0 gives 0, 1 gives 1, R/G/B/A give the compare result. Return each dmask register from its own select, and throw only for the reserved selects 2 and 3.
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.
