31 ; then the simple loop which checks each byte for zero.
40 ; if ( y & z ) = 0 then all bytes in dataWord are non-zero
42 ; The test maps any non-zero byte to zeros and any zero byte to 0x80,
43 ; with one exception: 0x01 bytes preceeding the first zero are also
72 beq LLoop ; if r4 is zero, then all bytes are non-zero
74 ; Now we know one of the bytes in r8 is zero,
78 ; 0x01 bytes preceeding the first zero are also mapped to 0x80.
