Where is there documentation on how to write inline asm?

[pineapple]

I've managed to get a few functions working before mostly by 
copying whatever Phobos was doing for a similar purpose, but now 
that I'm trying to do something different I am really hitting a 
wall.

My issue is that I can't figure out how to access a function's 
arguments from within inline asm or how to ensure that the 
correct value is returned. I haven't found a single piece of 
documentation about this so far!

I am mainly concerned about doing this for naked asm functions, 
but any documentation on the subject would be helpful.
