Did you run clang under ARM kernel? (not cross)

I think no need patch to contrib/llvm if it use OABI only.
I don't know about EABI. (currently dropped EABI in my patch)
However, you can not use clang completely until other patch is applied.

1) no vmrs/vmsr op code (used by VFP) in contrib/binutils/gas/config/tc-arm.c
2) no enough text size in sys/arm/include/vmparam.h, config/RPI-B-test13 (32MB or more is 
recommended)
3) cannot change max text size in sys/arm/include/vmparam.h, sys/conf/options.arm

I don't know why MAX size under VA is limited so small.
The physical memory is allocated when it requires, isn't it?

Thanks,
