2 # This file tests how we handle a 16-bit direct jump. In particular, it tests
3 # whether we actually disallow prefix 66 on the direct jump.
5 # Define direct (16-bit) jump, which NaCl doesn't allow
8 # Padding in case the parser of the previous instruction recognizes
9 # the wrong byte length for the jump constant.
