The mass rebuild of openbios reveals an error in the cross-gcc cross compiler (powerpc64-linux-gnu-gcc). https://koji.fedoraproject.org/koji/taskinfo?taskID=12854344 https://kojipkgs.fedoraproject.org//work/tasks/4344/12854344/build.log powerpc64-linux-gnu-gcc $EXTRACFLAGS -m32 -msoft-float -fno-builtin-bcopy -fno-builtin-log2 -Os -g -DNATIVE_BITWIDTH_EQUALS_HOST_BITWIDTH -USWAP_ENDIANNESS -Wall -Wredundant-decls -Wshadow -Wpointer-arith -Wstrict-prototypes -Wmissing-declarations -Wundef -Wendif-labels -Wstrict-aliasing -Wwrite-strings -Wmissing-prototypes -Wnested-externs -Werror -MMD -MP -MT target/arch/ppc/qemu/ofmem.o -MF 'target/arch/ppc/qemu/ofmem.d' -I/builddir/build/BUILD/openbios-1.1/include -I/builddir/build/BUILD/openbios-1.1/kernel/include -I./target/include -c -o target/arch/ppc/qemu/ofmem.o /builddir/build/BUILD/openbios-1.1/arch/ppc/qemu/ofmem.c /tmp/ccRSW9xm.s: Assembler messages: /tmp/ccRSW9xm.s:544: Error: missing operand rules.mak:293: recipe for target 'target/arch/ppc/qemu/ofmem.o' failed I would file a bug about this, but I noticed that cross-gcc is at version 5.2.1. Are we going to update it to 6.0? If so, are there any testing packages that you would like me to try?
