// Used as part of emulator detection. The dynarec core of PJ64 4.0 only updates
// the COUNT register in between recompiled functions, so this will return 0 on
// PJ64 4.0 dynarec, but will instead return the count factor on other versions.

Added emulator detection (#651) * Added emulator detection * Fixed missing assignments * Disable interrupts around the count factor test * Added more comments to emutest * Changed PJ64 enum values so the versions work as a bitfield * Updated README * Fixed comments * Updated enum values so you can safely AND and OR all emulator version flags together * Remove redundant gIsConsole, gIsVC, and gCacheEmulated global variables * Changed console check to be more future proof against Ares * Use assembly file instead of casting to a function pointer * Moved round_double_to_float back to its own compilation unit * Moved the ParallelN64 check before the Ares check for better future-proofing * Align pj64_get_count_factor_asm with cache lines... not that it actually matters for pj64 * Adjusted some comments * Made emulator check thread-safe on emulators that emulate PI timings * Added gIsConsole macro for backwards compatibility * Added cen64 to INSTANT_INPUT_BLACKLIST * Updated comment 2023-08-28 18:03:26 -04:00			`// Used as part of emulator detection.
