 9.26.2.4 Assembler Extensions
 .............................
 
 `@rN'
      As destination operand being treated as `0(rn)'
 
 `0(rN)'
      As source operand being treated as `@rn'
 
 `jCOND +N'
      Skips next N bytes followed by jump instruction and equivalent to
      `jCOND $+N+2'
 
 
    Also, there are some instructions, which cannot be found in other
 assemblers.  These are branch instructions, which has different opcodes
 upon jump distance.  They all got PC relative addressing mode.
 
 `beq label'
      A polymorph instruction which is `jeq label' in case if jump
      distance within allowed range for cpu's jump instruction. If not,
      this unrolls into a sequence of
             jne $+6
             br  label
 
 `bne label'
      A polymorph instruction which is `jne label' or `jeq +4; br label'
 
 `blt label'
      A polymorph instruction which is `jl label' or `jge +4; br label'
 
 `bltn label'
      A polymorph instruction which is `jn label' or `jn +2; jmp +4; br
      label'
 
 `bltu label'
      A polymorph instruction which is `jlo label' or `jhs +2; br label'
 
 `bge label'
      A polymorph instruction which is `jge label' or `jl +4; br label'
 
 `bgeu label'
      A polymorph instruction which is `jhs label' or `jlo +4; br label'
 
 `bgt label'
      A polymorph instruction which is `jeq +2; jge label' or `jeq +6;
      jl  +4; br label'
 
 `bgtu label'
      A polymorph instruction which is `jeq +2; jhs label' or `jeq +6;
      jlo +4; br label'
 
 `bleu label'
      A polymorph instruction which is `jeq label; jlo label' or `jeq
      +2; jhs +4; br label'
 
 `ble label'
      A polymorph instruction which is `jeq label; jl  label' or `jeq
      +2; jge +4; br label'
 
 `jump label'
      A polymorph instruction which is `jmp label' or `br label'
