[webkit-help] 3 instructions

[Fern Moon]

Hi,

I am testing the interpreter in webkit.  And I always find that the
following 3 instructions get compiled, but never get executed in the
interpreter.

[   0] enter
[   1] sub		 r0, r-10, r-9
[   6] ret		 r0

What are those instructions for ?  Will them get executed someplace else?

Thanks,
Fern
