The Windows EnterMode stub added in ca8cedd83f uses pxFailRel, but
nothing in this TU's include chain declares it on Windows — the Linux
build never compiles that branch, so it got past the local gate and
died only on the Windows CI leg.
Both are yaps2 offline-diagnostic TUs that had never seen a Windows
build (yaps2 is Linux-only); they were the last two compile failures
on the arm64 Windows CI leg.
vu_capture.cpp only needed getpid — now a capture_pid() helper that
uses _getpid/<process.h> on Windows; the probe itself is fully
functional there.
microVU_Divtrace's capture mechanism is SIGTRAP + ucontext (the JIT
emits brk, the handler snapshots vuRegs and advances the faulting PC),
which has no Windows equivalent — the signal machinery compiles out,
while the shared globals and FingerprintRegs stay so the interp/JIT
consumer sites link unchanged. EnterMode pxFailRel's loudly on Windows
so a future replay-driver port can't mistake an unhandled brk for a
JIT crash. Only the offline replay drivers call it, and they don't
build on Windows.
recompiler_tests 1359/1359 on linux-arm64.
Darwin's <ucontext.h> #errors without _XOPEN_SOURCE; use <sys/ucontext.h> for the ucontext_t type (mirrors CrashHandler.cpp / DarwinMisc.cpp) and read PC via uc_mcontext->__ss.__pc on Apple. Linux arm64 path is unchanged.
Only compiled under PCSX2_RECOMPILER_TESTS.
DiffJitVsInterp harness (EE/IOP/VU synthetic JIT-vs-interpreter tests) plus the
shared capture/divergence-localizer infrastructure (vu_capture, ee_divtrace,
microVU_Divtrace, VU1Trace) and the test hooks they install in interp/GIF/COP2 paths.
All hook sites are guarded by PCSX2_RECOMPILER_TESTS and compile out of release builds.
