[ale] Q: RTFM pointer to GCC calling conventions on x86 targets

[Stephan Uphoff]

Take a look at:

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

and

	http://www.linux.com/howto/Assembly-HOWTO.html

There is also document called:
 "Tool Interface Standard (TIS) Portable Formats Specification"
available from Intel's developer website (sorry no link) that you
might find useful.  


Good luck
