Certainly, using the feature flags is a far more appropriate approach than maintaining a list of CPU types known to work, and not at least having a list of them would be (is?) VERY bad -- assuming, of course, that the features needed *have* flags. Using the Linux-specific information from /proc/cpuinfo may or may not be the best way to do it (of course, the CPU-provided flags will not tell us things like f00f_bug...), depending on whether we want dosemu to work on anything but Linux (and on what other systems it works (or could easily be made to work) on right now). Unfortunately, I have no idea what CPU features dosemu actually requires on x86_64... ------------------------------------------------------------------------------ Come build with us!
