[Top posted note: I have submitted bugzilla 220024 for this powerpc64 and powerpc issue. It has also been reproduced when using /usr/local/powerpc64-freebsd/bin/ for binutils for a powerpc64 buildworld attempt.] On 2017-Jun-15, at 11:32 PM, Mark Millard <markmi at dsl-only.net> wrote: [powerpc64 has the same problem.] On 2017-Jun-15, at 9:34 PM, Mark Millard <markmi_at_dsl-only.net> wrote: > [I should have listed more about my build context for clang.] > > On 2017-Jun-15, at 9:20 PM, Mark Millard <markmi at dsl-only.net> wrote: > >> [A gcc 4.2.1 based buildworld buildkernel did not have this problem.] >> >> On 2017-Jun-15, at 5:34 PM, Mark Millard <markmi at dsl-only.net> wrote: >> >>> Context: amd64 -> powerpc cross build of -r319936 >>> (one of my usual clang-based experiments): >>> >>> --- all_subdir_sys --- >>> Building /usr/obj/powerpcvtsc_clang/powerpc.powerpc/usr/src/sys/boot/powerpc/boot1.chrp/boot1.elf >>> --- boot1.elf --- >>> boot1.o: In function `fsread_size': >>> /usr/src/sys/boot/powerpc/boot1.chrp/boot1.c:(.text+0x14b8): undefined reference to `__udivdi3' >>> /usr/src/sys/boot/powerpc/boot1.chrp/boot1.c:(.text+0x1508): undefined reference to `__udivdi3' >>> cc: error: linker command failed with exit code 1 (use -v to see invocation) >>> --- all_subdir_lib --- >>> Building /usr/obj/powerpcvtsc_clang/powerpc.powerpc/usr/src/lib/msun/s_remquo.po >>> --- all_subdir_sys --- >>> *** [boot1.elf] Error code 1 >>> >>> make[6]: stopped in /usr/src/sys/boot/powerpc/boot1.chrp >>> .ERROR_TARGET='boot1.elf' >>> .ERROR_META_FILE='/usr/obj/powerpcvtsc_clang/powerpc.powerpc/usr/src/sys/boot/powerpc/boot1.chrp/boot1.elf.meta' >>> >>> >>> # Meta data file /usr/obj/powerpcvtsc_clang/powerpc.powerpc/usr/src/sys/boot/powerpc/boot1.chrp/boot1.elf.meta >>> CMD cc -target powerpc-unknown-freebsd12.0 --sysroot=/usr/obj/powerpcvtsc_clang/powerpc.powerpc/usr/src/tmp -B/usr/obj/powerpcvtsc_clang/powerpc.powerpc/usr/src/tmp/usr/bin -ffreestanding -msoft-float -I/usr/src/sys/boot/powerpc/boot1.chrp/../../common -I/usr/src/sys/boot/powerpc/boot1.chrp/../../../ -D_STANDALONE -std=gnu99 -Qunused-arguments -nostdlib -static -Wl,-N -o boot1.elf boot1.o ashldi3.o syncicache.o >>> CWD /usr/obj/powerpcvtsc_clang/powerpc.powerpc/usr/src/sys/boot/powerpc/boot1.chrp >>> TARGET boot1.elf >>> -- command output -- >>> boot1.o: In function `fsread_size': >>> /usr/src/sys/boot/powerpc/boot1.chrp/boot1.c:(.text+0x14b8): undefined reference to `__udivdi3' >>> /usr/src/sys/boot/powerpc/boot1.chrp/boot1.c:(.text+0x1508): undefined reference to `__udivdi3' >>> cc: error: linker command failed with exit code 1 (use -v to see invocation) >>> *** Error code 1 >>> >>> Note: This was -j16 for the build. >>> >>> I updated /usr/src and amd64 to -r319991 and then >>> retried cross building for powerpc: same result. >>> >>> >>> Note: I'd frozen at -r317820 until this update.
