Apple clang-1300.0.29.3 (ships with macOS 11.6) requires to use -Wno-shorten-64-to-32 and -Wsnoign-conversion, or explicitly cast to smaller type or signed type.
immediate is int64_t and opsize is 4 bits field which makes mask clearly no more than 5 bits => cast to uint8_t is safe here and just makes clang happy and code clean.
buf[] is also uint8_t and cast happened before but implicitly.
