I'm using LLVM 2.6 to buid Linux 2.6.31-git. I read here and old thread about kernel and llvm-2.3 [1] so I'd like to ask again. # make CROSS_COMPILE=llvm- V=1 (...) llvm-gcc -Wp,-MD,init/.main.o.d -nostdinc -isystem /usr/lib/llvm-gcc-4.2-2.6/lib/gcc/i686-pc-linux-gnu/4.2.1/include -Iinclude -I/opt/linux-2.6/arch/x86/include -include include/linux/autoconf.h -D__KERNEL__ -Wall -Wundef -Wstrict-prototypes -Wno-trigraphs -fno-strict-aliasing -fno-common -Werror-implicit-function-declaration -Wno-format-security -fno-delete-null-pointer-checks -Os -m32 -msoft-float -mregparm=3 -freg-struct-return -mpreferred-stack-boundary=2 -march=i686 -mtune=core2 -mtune=generic -Wa,-mtune=generic32 -ffreestanding -DCONFIG_AS_CFI=1 -DCONFIG_AS_CFI_SIGNAL_FRAME=1 -pipe -Wno-sign-compare -fno-asynchronous-unwind-tables -mno-sse -mno-mmx -mno-sse2 -mno-3dnow -fno-stack-protector -fno-omit-frame-pointer -fno-optimize-sibling-calls -pg -Wdeclaration-after-statement -Wno-pointer-sign -fno-strict-overflow -D"KBUILD_STR(s)=#s" -D"KBUILD_BASENAME=KBUILD_STR(main)" -D"KBUILD_MODNAME=KBUILD_STR(main)" -c -o init/.tmp_main.o init/main.c UNREACHABLE executed! init/main.c:908: internal compiler error: Aborted Please submit a full bug report, with preprocessed source if appropriate.

What are the modification to the make system. Just some changes in Makefile or some changes on kernel machine specific files? [1] http://markmail.org/message/wekbyc5ju2eh32m3 --tm
Hi Tiago, please open a bug report. Use -save-temps to get the preprocessed compiler output (.i) and attach that to the bug-report. Also, please rerun that failing compile line by hand, but adding -emit-llvm to the command line. If it compiles successfully, then please attach the resulting .o to the bug report.> UNREACHABLE executed! > init/main.c:908: internal compiler error: AbortedCiao, Duncan.
