Working-tree snapshot taken 2026-07-28 so this work is not lost. To be clear
about provenance: NONE of this was written in the session that committed it —
it is pre-existing uncommitted work on phase-a-tracing, last committed 2026-07-09,
from the xenia-rs decoder/deadlock investigation. It is recorded verbatim, not
reviewed and not tested.
Contents: 24 tracked modifications (ppc_emit_memory, xex_module, object_table,
shim_utils, xboxkrnl threading/rtl, xevent/xobject/xthread, memory) plus the
untracked probe sources audit_68_host_mem_watch, audit_69_event_signal_watch,
audit_70_semaphore_release_watch, phase_b_snapshot, and cmake/toolchains.
Deliberately excluded: build-cross/ (51 GB of build output) and
vkd3d-proton.cache. Note third_party/snappy is a submodule pointer change whose
target may not be pushed anywhere, so this branch is a preservation record rather
than a guaranteed-buildable tree.

GTK3, system SDL2 (pkg-config), Linux link libraries, linker groups,
and _GLIBCXX_DEBUG were in the generic non-MSVC branch, breaking
cmake configure on non-Linux POSIX platforms.
zstd ships a hand-written huf_decompress_amd64.S that was being
disabled on all non-MSVC builds. New behavior matches zstd's own
CMakeLists which enables it on GCC/Clang x86_64 and disables it
on MSVC and non-x86 architectures.
PCLMULQDQ CRC folding is excluded for now due to a runtime hang on
Linux — needs further investigation. The library does runtime feature
detection so all other paths should be safe on CPUs without these extensions.
Based entirely off existing xbyak x86 implementation and available
tests. Still needs a lot of optimization and testing on non-Windows
platforms.
So far passes all tests and boots at least some games on Windows.
