Except I’m wondering if FreeMiNT (userspace) will get shared libraries some day. It would help Debian GNU/MiNT ☺ > 4) Running GCC on ColdFire.

That would need to be addressed during porting, sure. We basically need a userspace CPU switch between: - 68020+ or CF, no distinguishing needed (generic mode) - 68020+ (generic) - some as-of-yet unspecified CF baseline (generic) High-performance applications could then also distinguish between different 680x0 implementations, etc. but most of the code would need to work on both unmodified, and some (like those libraries using asm code) could be changed to detect the CPU and use the appropriate routines instead. > Anyway, I would love using Debian on my FireBee :-) When you express it like this… 233 MHz is already faster than what I can emulate, and I’ve heard of CF up to 400… bye, //mirabilos -- “Having a smoking section in a restaurant is like having a peeing section in a swimming pool.” -- Edward Burr -- To UNSUBSCRIBE, email to debian-68k-requ...@lists.debian.org with a subject of "unsubscribe".
