One that can convert between NASM or MASM or Gas is at http://hermes.terminal.at/intel2gas/ Note that this program was designed to convert from gas to nasm; conversion from nasm to gas is spotty, and the data files used needed extensive modification to even nearly get floating point in gas correct. I can make the changes available, but this program is not ready for wholesale conversion of very large amounts of Intel floating point source. jasonp _ Unsubscribe list info -- http://www.scruz.net/~luke/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers
Re: Mersenne: primes source
It would be easier to convert the source from MASM to NASM. Both use intel syntax. NASM is free and its source code available. This is a list of the object formats it supports. if I recall correctly, the assembler code also makes extensive use of the MASM macro facilities to generate highly repetitious code sequences. Do NASM's macros work the same as MASM's? There are a lot of subtle things going on in MASM when you get into nested macros and parameter expansions and so forth. -jrp _ Unsubscribe list info -- http://www.scruz.net/~luke/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers
Re: Mersenne: primes source
I have a question though. Why make the Linux source dependant on code which needs to be assembled under DOS, when there is an assembler for Linux (as) ? Probably because of the hugely differing syntax and macro facilities. The assembler code was originally written with MASM on a Microsoft platform, if you feel up for converting it to `as` by all means, feel free. Make sure the resultant macro expansions are identical to the last byte of binary code. -jrp _ Unsubscribe list info -- http://www.scruz.net/~luke/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers

Also, the source seems to be released something like "feel free to use this code to make the world a better place as you see fit", but doesn't actually have a license. I would incourage you to release it under either the GNU General Public License (http://www.gnu.org/copyleft/gpl.html), or if you want to allow commercial use, the BSD license (which I'm significantly less familiar with). I may look into changing this when the v19 sources are released.
