|

|
|
|

|
|
<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.
