Black Myth: Wukong (PPSA23226) exits at start-up with
STATUS_DLL_NOT_FOUND after "Failed to load module:
libs\libSceDbgThreadSanitizer.prx". The executable does not need the
library: its bundled sce_module/libSceJobManager_nosubmission.prx lists
it in DT_NEEDED and imports __tsan_acquire and __tsan_release from it,
plus sceKernelIsThreadSanitizerEnabled from libkernel. The relinker
converts every module in sce_module and loads it at start-up (only
--module-dir directories are deferred), and GuestModuleBuilder adds each
module's host dependencies to the executable's DT_NEEDED, which the
Windows start-up stub loads.
libSceDbgThreadSanitizer now exports __tsan_acquire and __tsan_release
with the void(void* addr) signatures of LLVM compiler-rt's
tsan_interface.h (llvm-project 87f0227cb601, LLVM 20.1.8). Both throw:
AnyPS5 runs no race detector, and the module calls them only after
sceKernelIsThreadSanitizerEnabled reports the sanitizer enabled.
libkernel's sceKernelIsThreadSanitizerEnabled returns 0, as
sceKernelIsAddressSanitizerEnabled does; its int(void) signature is
assumed and recorded in the libkernel debt file.
