-
- <a name="index-directives-for-SCORE"></a>
- <a name="index-SCORE-directives"></a>
- <p>A number of assembler directives are available for SCORE. The
- following table is far from complete.
- </p>
- <dl compact="compact">
- <dt><code>.set nwarn</code></dt>
- <dd><p>Let the assembler not to generate warnings if the source machine
- language instructions happen data dependency.
- </p>
- </dd>
- <dt><code>.set fixdd</code></dt>
- <dd><p>Let the assembler to insert bubbles (32 bit nop instruction /
- 16 bit nop! Instruction) if the source machine language instructions
- happen data dependency.
- </p>
- </dd>
- <dt><code>.set nofixdd</code></dt>
- <dd><p>Let the assembler to generate warnings if the source machine
- language instructions happen data dependency. (Default)
- </p>
- </dd>
- <dt><code>.set r1</code></dt>
- <dd><p>Let the assembler not to generate warnings if the source program
- uses r1. allow user to use r1
- </p>
- </dd>
- <dt><code>set nor1</code></dt>
- <dd><p>Let the assembler to generate warnings if the source program uses
- r1. (Default)
- </p>
- </dd>
- <dt><code>.sdata</code></dt>
- <dd><p>Tell the assembler to add subsequent data into the sdata section
- </p>
- </dd>
- <dt><code>.rdata</code></dt>
- <dd><p>Tell the assembler to add subsequent data into the rdata section
- </p>
- </dd>
- <dt><code>.frame "frame-register", "offset", "return-pc-register"</code></dt>
- <dd><p>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".
- </p>
- </dd>
- <dt><code>.mask "bitmask", "frameoffset"</code></dt>
- <dd><p>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.
- </p>
- </dd>
- <dt><code>.ent "proc-name"</code></dt>
- <dd><p>Set the beginning of the procedure "proc_name". Use this directive
- when you want to generate information for the debugger.
- </p>
- </dd>
- <dt><code>.end proc-name</code></dt>
- <dd><p>Set the end of a procedure. Use this directive to generate information
- for the debugger.
- </p>
- </dd>
- <dt><code>.bss</code></dt>
- <dd><p>Switch the destination of following statements into the bss section,
- which is used for data that is uninitialized anywhere.
- </p>
- </dd>
