Both dominance analyses start from sorted unique sets and intersect them.
Insert the current block ID with lower_bound instead of sorting again.
Preserve every intermediate set and the existing ID-order iteration.
Keep the generic unsorted helper and all graph rewrite logic unchanged.
Compare both analyses against the original algorithms on six raw CFGs.
Cover finite loops, closed SCCs, unreachable islands and permuted IDs.
With SDL's disk driver no pad audio device is open, so AudioOut2MixPorts
runs with no pad output. A vibration port and a mono pad speaker port
are pushed together: only the speaker's data reaches the main mix, and
a vibration port alone leaves it silent.
Without a DualSense audio device every AudioOut2 port was mixed into the
main output, including PAD_VIBRATION ports. Their waveforms drive the
controller's actuators on the console and are never heard; mixed into
the speakers they made PPSA28997's combat about 20 dB louder than its
dialogue. Vibration ports are now left out in that case; pad speaker
ports still go to the main output.
The f16 min/max/min3/max3/med3 now pick NaN results on the bits and
quiet a signaling NaN only with IEEE=1. With IEEE=0, v_min_f64 and
v_max_f64 return the other operand for a NaN, not a quieted NaN. This
completes #1826 for these forms, as measured on RDNA2 (gfx1036).

With IEEE_MODE=1 the hardware quiets a signaling NaN that v_cubesc,
v_cubetc or v_cubema_f32 returns, keeping the sign the instruction gives
it; with IEEE=0 the bits pass through. Same rule as #1867, measured on
gfx1036 in both modes.

Neither existed under the guest root, so opening them failed and titles
that then read from the descriptor crashed. Opening either for reading
now returns a descriptor whose reads, positioned reads and vector reads
fill the buffer from the host's random device, as
sceRandomGetRandomNumber does. Opening them for writing throws.

The executable is linked at a fixed base with a __PAGEZERO that fills the space below it, and
the guest assumes 16 KB pages. With MH_PIE set dyld slides the image by a multiple of 4 KB,
which breaks that assumption and ends in a SIGBUS (KERN_PROTECTION_FAILURE) in about half of
the launches under Rosetta 2. Clearing the flag keeps the image at its linked address.
test_macos_output.py now reads the header flags and checks that MH_PIE is clear.

Since #1178 the SPI_PS_INPUT_ENA/ADDR emplace calls did nothing, so the registered variant had no pixel inputs, and null pixel draws took the last pixel shader's user SGPR count and the bound targets' export mapping. Registration now overwrites those registers, the draw gives the null program no user SGPRs and an empty export mapping, and the at-draw preparation is left for wave32 only. Root cause found by @Raghav314.
A draw that rasterizes both faces with different front and back depth
bias was rejected, since Vulkan has one depth bias per draw and the
cull mode is pipeline state. Such a draw is now recorded twice in the
same pass: front faces with the back faces culled and the front bias,
then back faces with the front faces culled and the back bias. A face
whose offset is disabled gets no bias.
#2279 made agc_driver_f32_arithmetic_nan fail on NVIDIA (Windows):
v_fmamk_f32 returns a quiet NaN where the signalling one is expected
(lane 1 no float mode v_fmamk_f32 is 0x7fc12345, expected 0x7f812345),
5/5 runs on main and 5/5 passing with #2279 reverted. CI's Windows job
skips the AGC execution tests, so it did not show there.
v_fma_legacy was rewritten as a split multiply and add after #2279; it
keeps that and gets back the invalid-product argument it passed before.
Fixes#2581
scePthreadCreate on Linux started guest threads with std::thread, so every
thread got the host default stack (RLIMIT_STACK, usually 8 MiB) whatever the
title asked for. A thread that asks for more than that and uses it crashes
with SIGSEGV. Once the thread ran, scePthreadAttrGet also reported the host
size instead of the requested one.
Create the thread with pthread_create and a stack of the requested size plus
what glibc keeps at its top (static TLS, the thread control block and the
start_thread frame). That reserve is measured once with a probe thread.
The thread reports [top - reserve - size, top - reserve) as its stack, as
Windows reports [top - size, top), and the creator waits until the range is
set, as on Windows.
