It's not easy though. I have been trying to bisect the problem for several days now, see: https://github.com/rust-lang/rust/issues/50960 There are also other important tasks on PowerPC that need to be worked on, most importantly the transition from Yaboot to GRUB for PowerPC Macs (we are already using GRUB for IBM PowerPC machines on powerpc and ppc64). Frank Scheiner has worked on the GRUB support for Macintosh, but there is still one unresolved issue. Switching from Yaboot to GRUB would alleviate all the boot problems people have when using Yaboot which doesn't support many modern filesystems or even ext4 features. >> Nice.

I don't think there are good chances to get JIT support for PowerPC merged into Firefox upstream, but if someone would do the job and be willing to maintain the code, it can happen. > I saw people mentioning that playing videos with mplayer, vlc etc is slow on > G4 machines.

Issues should be compiled into a list and reported as bugs, tagged accordingly: User: debian-powerpc@lists.debian.org Usertags: powerpc X-Debbugs-CC: debian-powerpc@lists.debian.org Please always check for existing bugs first and tag them if they haven't already been tagged.
