This allows me to experimentally break stuff without having to check it in first. It also give me a way to build bootable images for when (not “if”!) I mess things up properly on the RPI.

If I fix that with a symlink, clang then objects to the -ffixed-r8 option. Clang has an equivalent -ffixed-r9, but the u-boot that is mandated for FreeBSD/Arm/RPI use doesn’t have the R9 fix. > > Questions: > > 1) Are you aware of any of this?

Long-term, we’d all like to see U-Boot build with clang. No idea yet whether that’s hard or not. No idea if I’ll have time to work on it in the near future. Timhome | help
