      Description

        https://developer.apple.com/documentation/apple_silicon/porting_just-in-time_compilers_to_apple_silicon?language=objc

        On Apple Silicon, it will be impossible to have memory regions that are writable and executable at the same time.

        We should investigate possibility to use pthread_jit_write_protect_np together with MAP_JIT (JDK-8234930)
