Subject: [PATCH] sh: Fix build with CONFIG_UBSAN=y
Date: Tue, 30 Jan 2024 15:27:23 -0800 [thread overview]
Message-ID: <20240130232717.work.088-kees@kernel.org> (raw)

not supported. Disable it for this part of the build.
sh4-linux-ld: arch/sh/boot/compressed/misc.o: in function `zlib_inflate_table':
misc.c:(.text+0x670): undefined reference to `__ubsan_handle_shift_out_of_bounds'
Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202401310416.s8HLiLnC-lkp@intel.com/
