However, when trying to compile score defconfig, I get internal compiler errors in cc1 when compiling drivers/tty/tty_mutex.o and block/elevator.o. CC block/elevator.o score-elf-gcc: internal compiler error: Segmentation fault (program cc1) 0x40c073 execute ../../gcc/gcc/gcc.c:2848 Please submit a full bug report, with preprocessed source if appropriate. Please include the complete backtrace with any bug report. See <http://gcc.gnu.org/bugs.html> for instructions. make[1]: *** [block/elevator.o] Error 4 make: *** [block/elevator.o] Error 2 Do you see that as well ? This is with GNU assembler version 2.24.51 (score-elf) using BFD version (GNU Binutils) 2.24.51.20140622 and gcc configured with: Configured with: ../gcc/configure --prefix=/opt/kernel/score --program-prefix=score-elf- \ --target=score-elf --without-header --disable-nls --enable-languages=c --disable-threads \ --disable-shared --enable-werror=no target_configargs=enable_vtable_verify=yes \ --enable-obsolete --disable-libssp --disable-libquadmath Tip of gcc source is commit d8686b0aa945a, tip of binutils source is commit d17c74c1d41. Your assembler fix is included in this version of binutils.
