16 bit nop! Instruction) if the source machine language instructions

happen data dependency.

"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".

function’s stack frame, this is for the debugger to explain the

frame chain.

</dd>
|

<dt><code>.ent "proc-name"</code></dt>

when you want to generate information for the debugger.
