Recent versions of Gas, perhaps not available for djgpp(?), have an ".intel_syntax noprefix" switch, which produces *less* steam. It wasn't added for gcc's convenience, so the argument that Gas is "only fit for gcc's output" is no longer true. (although it *was*, at one time!!!) I'm one of Nasm's biggest fans, and I don't think you'll go far wrong choosing Nasm... *but*... Nasm doesn't have 64-bit support, and isn't likely to, soon. Gas (and Fasm and Yasm) do. This might influence your decision! Why not become "bilingual"? I can't *write* anything in Gas without making a lot of syntax errors, but I can read it and figure out what it's doing... usually. Pretty handy to have *some* familiarity with both! (Fasm and Yasm are similar enough to Nasm that they almost come free... couple subtleties...) As far as a tutorial... other than Dr. Carter's... Maybe: http://docs.cs.up.ac.za/programming/asm/derick_tut/ http://www.leto.net/writing/nasm.txt http://www.rawcode.org/ This last is brand new - mostly in Italian (except for the code, which is in Intel), but being translated to English "as we speak" - and the guy is looking for help! Seems to me there are a couple more - I can't find links right now - none of 'em as extensive as Dr. Carter's... http://www.linuxassembly.org is a good place to look for info and links... Best, Frank P.S. For BSD, add the BSD Developer's Handbook, chapter... 17, I think? You can find it. *Very* good! - To unsubscribe from this list: send the line "unsubscribe linux-assembly" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
