#### 9.33.2 SCORE Assembler Directives

A number of assembler directives are available for SCORE. The following table is far from complete.

`.set nwarn`
  Let the assembler not to generate warnings if the source machine language instructions happen data dependency.
`.set fixdd`
  Let the assembler to insert bubbles (32 bit nop instruction / 16 bit nop! Instruction) if the source machine language instructions happen data dependency.
`.set nofixdd`
  Let the assembler to generate warnings if the source machine language instructions happen data dependency. (Default)
`.set r1`
  Let the assembler not to generate warnings if the source program uses r1. allow user to use r1
`set nor1`
  Let the assembler to generate warnings if the source program uses r1. (Default)
`.sdata`
  Tell the assembler to add subsequent data into the sdata section
`.rdata`
  Tell the assembler to add subsequent data into the rdata section
`.frame "frame-register", "offset", "return-pc-register"`
  Describe a stack frame. "frame-register" is the frame register, "offset" is the distance from the frame register to the virtual frame pointer, "return-pc-register" is the return program register. You must use ".ent" before ".frame" and only one ".frame" can be used per ".ent".
`.mask "bitmask", "frameoffset"`
  Indicate which of the integer registers are saved in the current function's stack frame, this is for the debugger to explain the frame chain.
`.ent "proc-name"`
  Set the beginning of the procedure "proc_name". Use this directive when you want to generate information for the debugger.
`.end proc-name`
  Set the end of a procedure. Use this directive to generate information for the debugger.
`.bss`
  Switch the destination of following statements into the bss section, which is used for data that is uninitialized anywhere.
