 9.39.3 Assembler Directives
 ---------------------------
 
 The RX version of 'as' has the following specific assembler directives:
 
 '.3byte'
      Inserts a 3-byte value into the output file at the current
      location.
 
 '.fetchalign'
      If the next opcode following this directive spans a fetch line
      boundary (8 byte boundary), the opcode is aligned to that boundary.
      If the next opcode does not span a fetch line, this directive has
      no effect.  Note that one or more labels may be between this
      directive and the opcode; those labels are aligned as well.  Any
      inserted bytes due to alignment will form a NOP opcode.
