Hi folks,

in our copy of GCC, it looks like the ARMv3 stuff is not yet removed.
I'm not sure maintaining just-before-ARMv4 is that hard, assuming ARMv4

Does this diff help?

I get this when compiling:
/usr/src/current/sys/arch/arm/arm/bcopyinout.S:717: Error: selected processor does not support `ldrh r3,[r0]' in ARM mode
/usr/src/current/sys/arch/arm/arm/bcopyinout.S:721: Error: selected processor does not support `strh r3,[r1]' in ARM mode

I also tried with -a arm, but that kernel panicked soon after doing podule enumeration.
