Can you describe what is extra compared to PAS_ASSERT_WITH_DETAIL in ChangeLog? (feature putting values to specific registers before crashing etc.).
And let's also mention to PAS_DEBUG_LOG_TO_SYSLOG's extension.

> Source/bmalloc/libpas/src/libpas/pas_log.c:97
> +#pragma clang diagnostic push
> +#pragma clang diagnostic ignored "-Wformat-nonliteral"

Use `PAS_IGNORE_WARNINGS_BEGIN("format-nonliteral")`

> Source/bmalloc/libpas/src/libpas/pas_log.c:99
> +#pragma clang diagnostic pop

Put PAS_IGNORE_WARNINGS_END

> Source/bmalloc/libpas/src/libpas/pas_utils.c:94
> +        pas_crash_with_info_impl((uint64_t) format, 0, 0, 0, 0, 0, 0);

Let's remove space between (uint64_t) format

> Source/bmalloc/libpas/src/libpas/pas_utils.c:110
> +    pas_crash_with_info_impl((uint64_t) filename, line, (uint64_t) function, (uint64_t) expression, 0xbeefbff0, 42, 1337);

Ditto.

> Source/bmalloc/libpas/src/libpas/pas_utils.c:117
> +    pas_crash_with_info_impl((uint64_t) filename, line, (uint64_t) function, (uint64_t) expression, extra, 1337, 0xbeef0bff);

Ditto.

I think I've waited long enough for api-ios.

I've reverted this file's change because these code can be used in the hot path, and we should keep things all inlined.
So, if we would like to collect more information, let's check things & add assertion in enumeration side :)
They are super cold code, so any perf problem does not matter.
