In particular, inline assembly doesn't have # the complete context available to resolve expressions. This is # intentional to avoid divergence in the resulting assembly code. # # We can work around this issue by borrowing a workaround done for ARM, # i.e. not directly testing the labels themselves, but by moving the # current output pointer by a value that should always be zero. If this # value is not null, then we will trigger a backward move, which is # explicitly forbidden. # # Signed-off-by: Bill Wendling <morbo@google.com> # [mpe: Put it in a macro and only do the workaround for clang] # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20201120224034.191382-4-morbo@google.com # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 cedd76eece11cab713330980da3fc04bd2462e86 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powerpc-randconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- randconfig KCONFIG_SEED=0x46EE1F2E # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_CPU_BIG_ENDIAN=y # Added to kconfig CONFIG_PPC64=y # Added to kconfig CONFIG_PPC_DISABLE_WERROR=y # Added to kconfig CONFIG_SECTION_MISMATCH_WARN_ONLY=y # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # Added to kconfig CONFIG_CC_STACKPROTECTOR_STRONG=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_LD_HEAD_STUB_CATCH=y # Added to kconfig CONFIG_TRIM_UNUSED_KSYMS=n # Added to kconfig CONFIG_UBSAN=n # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powerpc-randconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powerpc-randconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:4260:warning: override: reassigning to symbol PPC_DISABLE_WERROR .config:4261:warning: override: reassigning to symbol SECTION_MISMATCH_WARN_ONLY .config:4262:warning: override: reassigning to symbol PREVENT_FIRMWARE_BUILD .config:4267:warning: override: reassigning to symbol UBSAN # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powerpc-randconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/arch/powerpc/kernel/iommu.c:136:30: warning: 'fail_iommu_bus_notifier' defined but not used [-Wunused-variable] static struct notifier_block fail_iommu_bus_notifier = { ^ /kisskb/src/fs/btrfs/tree-checker.c: In function 'check_root_item': /kisskb/src/fs/btrfs/tree-checker.c:1056:9: warning: missing braces around initializer [-Wmissing-braces] struct btrfs_root_item ri = { 0 }; ^ /kisskb/src/fs/btrfs/tree-checker.c:1056:9: warning: (near initialization for 'ri.inode') [-Wmissing-braces] arch/powerpc/../../virt/kvm/vfio.o: In function `.kvm_vfio_group_set_kvm': vfio.c:(.text+0x7a): relocation truncated to fit: R_PPC64_TOC16_HA against undefined symbol `vfio_group_set_kvm' arch/powerpc/../../virt/kvm/vfio.o: In function `.kvm_vfio_group_put_external_user': vfio.c:(.text+0xe6): relocation truncated to fit: R_PPC64_TOC16_HA against undefined symbol `vfio_group_put_external_user' arch/powerpc/../../virt/kvm/vfio.o: In function `.kvm_vfio_update_coherency.isra.10': vfio.c:(.text+0x172): relocation truncated to fit: R_PPC64_TOC16_HA against undefined symbol `vfio_external_check_extension' arch/powerpc/../../virt/kvm/vfio.o: In function `.kvm_vfio_set_attr': vfio.c:(.text+0x50e): relocation truncated to fit: R_PPC64_TOC16_HA against undefined symbol `vfio_group_get_external_user' vfio.c:(.text+0x752): relocation truncated to fit: R_PPC64_TOC16_HA against undefined symbol `vfio_external_group_match_file' make[1]: * [/kisskb/src/Makefile:1164: vmlinux] Error 1 make: * [Makefile:185: __sub-make] Error 2 Command 'make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powerpc-randconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/powerpc-next-rand_powerpc-randconfig_powerpc-gcc4.9 # Build took: 0:03:51.424423
