(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, -- Daisuke Aoyama
