The wrong side of the war

I picked the wrong side...I've done a lot of work on PPC hardware, I think in Big Endian,
and I can read PPC assembly. With Apple's move to x86 hardware, how is that useful??

I thought this link provides a nice intro into stack frames and register usage in x86 assembly. This is very important - the x86 has so few registers that code that looks clean and simple on the PPC gets quite obtuse as things get juggled around. Between that, 453 addressing modes and 102,249 instructions, x86 assembler can look like the mad scribblings of Russel Crow in "A Beautiful Mind".

Any idea what this does? :-)
