• Description:
    From 0.17 You are allowed to use inlined assembler also in PowerPC code. It can be usefull for disassembler output etc. It currently doesn't support all of the simplified mnemonics and several of supervisor instructions aren't allowed. Please use it with care. You can also use normal PowerD comments.

  • Syntax: 
      ASM
    here should be your assembler routines
  ENDASM

  APROC compute(r3:L,r4:L,r5:L)(L)
    here should be your assembler routines
  ENDPROC

  • Special mnemonics to access PowerD variables:
    Following instructions allows You to access normal variables. 
    sb, sh, sw, sf, ss: to store byte, halfword, word, float double, float single
lb, lh, lw, lf, ls: to load  byte, halfword, word, float double, float single
la:                 to obtain the address of the variable

    The instruction format is: 
      <instruction> rx,var
