Folks might also give intel2gas a whirl; it goes both directions and
handles inline code as well as gas/MSVC/NASM syntaxes.  It's not perfect,
but it was very helpful with the last of the big pnggccrd.c functions
(opposite direction from what you want, though).

It used to be here but seems to have moved on:

According to freshmeat, this is the current home page:

	http://www.niksula.cs.hut.fi/~mtiihone/intel2gas/

However, it hasn't been updated in four years, and I'd bet there's a
newer version out there somewhere.  (Either way, it's simple enough to
add the 64-bit instructions to the existing lists of opcodes.)
