On Sat, Feb 07, 2015 at 12:50:34PM +0000 I heard the voice of Dimitry Andric, and lo! it spake thus: > > Log: > Pull in r224884 from upstream llvm trunk (by Keno Fischer): This blows up the kernel build for me. Apparently reproducible, as my first build was -j'd and so unreadable, and another non--j build yielded the below. With the rev patch -R'd out, build completes fine. cc -Werror -D_KERNEL -DKLD_MODULE -nostdinc -DHAVE_KERNEL_OPTION_HEADERS -include /usr/obj/usr/src/sys/MORTIS/opt_global.h -I. -I/usr/src/sys -I/usr/src/sys/contrib/altq -fno-common -g -fno-omit-frame-pointer -mno-omit-leaf-frame-pointer -I/usr/obj/usr/src/sys/MORTIS -mcmodel=kernel -mno-red-zone -mno-mmx -mno-sse -msoft-float -fno-asynchronous-unwind-tables -ffreestanding -fwrapv -fstack-protector -gdwarf-2 -Wno-error-tautological-compare -Wno-error-empty-body -Wno-error-parentheses-equality -Wno-error-unused-function -Wno-error-pointer-sign -Wall -Wredundant-decls -Wnested-externs -Wstrict-prototypes -Wmissing-prototypes -Wpointer-arith -Winline -Wcast-qual -Wundef -Wno-pointer-sign -fformat-extensions -Wmissing-include-dirs -fdiagnostics-show-option -Wno-unknown-pragmas -Wno-error-tautological-compare -Wno-error-empty-body -Wno-error-parentheses-equality -Wno-error-unused-function -Wno-error-pointer-sign -mno-aes -mno-avx -std=iso9899:1999 -c /usr/src/sys/modules/hptmv/../../dev/hptmv/hptproc.c Cannot emit physreg copy instruction UNREACHABLE executed at /usr/src/lib/clang/libllvmx86codegen/../../../contrib/llvm/lib/Target/X86/X86InstrInfo.cpp:3176!
