But in this case GCC is smart enough to notice that "base + # PLB4OPB_GESR0" will be constant, even though it's not something we can # immediately stringify into a register number. # # Segher pointed out that passing the register number to the inline asm # as a constant would be better, and in fact it fixes the build error, # presumably because it gives GCC a chance to resolve the value. # # While we're at it, change mtdcr() similarly. # # Reported-by: kernel test robot <lkp@intel.com> # Suggested-by: Segher Boessenkool <segher@kernel.crashing.org> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Acked-by: Feng Tang <feng.tang@intel.com> # Link: https://lore.kernel.org/r/20210218123058.748882-1-mpe@ellerman.id.au # < /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 b12483618d73c954c00faa49c276b4d9995fb95a # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc64_defconfig+UP_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc64_defconfig # Added to kconfig CONFIG_SMP=n # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc64_defconfig+UP_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_ppc64_defconfig+UP_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc64_defconfig+UP_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/drivers/net/ethernet/chelsio/cxgb4/sge.c: In function 'cxgb4_write_partial_sgl': /kisskb/src/drivers/net/ethernet/chelsio/cxgb4/sge.c:910:9: warning: missing braces around initializer [-Wmissing-braces] struct ulptx_sge_pair buf[MAX_SKB_FRAGS / 2 + 1] = {0}, *to; ^ /kisskb/src/drivers/net/ethernet/chelsio/cxgb4/sge.c:910:9: warning: (near initialization for 'buf[0]') [-Wmissing-braces] /kisskb/src/fs/btrfs/tree-checker.c: In function 'check_root_item': /kisskb/src/fs/btrfs/tree-checker.c:1064:9: warning: missing braces around initializer [-Wmissing-braces] struct btrfs_root_item ri = { 0 }; ^ /kisskb/src/fs/btrfs/tree-checker.c:1064:9: warning: (near initialization for 'ri.inode') [-Wmissing-braces] Completed OK # rm -rf /kisskb/build/powerpc-next_ppc64_defconfig+UP_powerpc-gcc4.9 # Build took: 0:03:27.925698
