| |
| <p><a name="index-directives-for-SCORE-2098"></a><a name="index-SCORE-directives-2099"></a>A number of assembler directives are available for SCORE. The |
| following table is far from complete. |
| |
| <dl> |
| <dt><code>.set nwarn</code><dd>Let the assembler not to generate warnings if the source machine |
| language instructions happen data dependency. |
| |
| <br><dt><code>.set fixdd</code><dd>Let the assembler to insert bubbles (32 bit nop instruction / |
| 16 bit nop! Instruction) if the source machine language instructions |
| happen data dependency. |
| |
| <br><dt><code>.set nofixdd</code><dd>Let the assembler to generate warnings if the source machine |
| language instructions happen data dependency. (Default) |
| |
| <br><dt><code>.set r1</code><dd>Let the assembler not to generate warnings if the source program |
| uses r1. allow user to use r1 |
| |
| <br><dt><code>set nor1</code><dd>Let the assembler to generate warnings if the source program uses |
| r1. (Default) |
| |
| <br><dt><code>.sdata</code><dd>Tell the assembler to add subsequent data into the sdata section |
| |
| <br><dt><code>.rdata</code><dd>Tell the assembler to add subsequent data into the rdata section |
| |
| <br><dt><code>.frame "frame-register", "offset", "return-pc-register"</code><dd>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". |
| |
| <br><dt><code>.mask "bitmask", "frameoffset"</code><dd>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. |
| |
| <br><dt><code>.ent "proc-name"</code><dd>Set the beginning of the procedure "proc_name". Use this directive |
| when you want to generate information for the debugger. |
| |
| <br><dt><code>.end proc-name</code><dd>Set the end of a procedure. Use this directive to generate information |
| for the debugger. |
| |
| <br><dt><code>.bss</code><dd>Switch the destination of following statements into the bss section, |
| which is used for data that is uninitialized anywhere. |
