    Intel2gas for x64 asm

    I've been looking at the program Intel2gas but it hasn't been updated in about 10 years, and is definitely not 64-bit compatible. This is a start to get 64-bit asm to work...

    Does anyone know about how to add an update to a program like this? It's in the repos...

    You could email az at debian.org or maybe try ubuntu-devel-discuss at lists.ubuntu.com and see what they think.
