[Tuxnes-devel] help w/ tuxnes asm

[Rigel <ri...@an...>]

Hi all,
My name is Rigel Freden, I live in southern Utah, USA, I am 18, a freshman at Southern Utah Univ. majoring in CS (anything else?).  I want to write an assembly port of tuxnes in MIPS (R2000).  I need help w/ x86 asm.

I already sent this to the Mighty Mike Master, but he suggested I join the mailing list...

All right.  I know all about AT&T style syntax, I know many x86 opcodes, but I've never seen this type of addressing mode.  This found on line 148 of table.x86 (in the BRK inst.), and looks like this: 
"leal   0x0(%ebp,%ebx,2),%ebp".  What's inside the parentheses?

Got one more.  there's a nice little couplet directly before the previous (lines 146,147) that looks like this:
testl  $0xff,%edi
setz   %bl

This sets bl when? is it when edi == 0xff ?

	Thanks much,
		Rigel Freden
