If panic_on_warn was set, # __ubsan_handle_divrem_overflow would panic. # # The problem is is that panic_on_warn is run time configurable. If it's # disabled, then we cannot guarantee that we will be able to recover # safely. Disable this config for clang until we can come up with a # solution in LLVM. # # Link: https://github.com/ClangBuiltLinux/linux/issues/1657 # Link: https://github.com/llvm/llvm-project/issues/56289 # Link: https://lore.kernel.org/lkml/CAHk-=wj1qhf7y3VNACEexyp5EbkNpdcu_542k-xZpzmYLOjiCg@mail.gmail.com/ # Reported-by: Sudip Mukherjee <sudipm.mukherjee@gmail.com> # Suggested-by: Linus Torvalds <torvalds@linux-foundation.org> # Signed-off-by: Nick Desaulniers <ndesaulniers@google.com> # Acked-by: Nathan Chancellor <nathan@kernel.org> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/sh4-linux/bin/sh4-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/sh4-linux/bin/sh4-linux-ld --version # < git log --format=%s --max-count=1 e5d523f1ae8f2cef01f8e071aeee432654166708 # < make -s -j 32 ARCH=sh O=/kisskb/build/linus_sh-allmodconfig_sh4-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/sh4-linux/bin/sh4-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # < make -s -j 32 ARCH=sh O=/kisskb/build/linus_sh-allmodconfig_sh4-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/sh4-linux/bin/sh4-linux- help # make -s -j 32 ARCH=sh O=/kisskb/build/linus_sh-allmodconfig_sh4-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/sh4-linux/bin/sh4-linux- olddefconfig # make -s -j 32 ARCH=sh O=/kisskb/build/linus_sh-allmodconfig_sh4-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/sh4-linux/bin/sh4-linux- Generating include/generated/machtypes.h <stdin>:1517:2: warning: #warning syscall clone3 not implemented [-Wcpp] /kisskb/src/arch/sh/kernel/machvec.c: In function 'sh_mv_setup': /kisskb/src/arch/sh/kernel/machvec.c:105:33: error: array subscript 'struct sh_machine_vector[0]' is partly outside array bounds of 'long int[1]' [-Werror=array-bounds] 105 \| sh_mv = (struct sh_machine_vector )&__machvec_start; \| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ In file included from /kisskb/src/arch/sh/kernel/machvec.c:13: /kisskb/src/arch/sh/include/asm/sections.h:7:13: note: while referencing '__machvec_start' 7 \| extern long __machvec_start, __machvec_end; \| ^~~~~~~~~~~~~~~ cc1: all warnings being treated as errors make[3]: * [/kisskb/src/scripts/Makefile.build:249: arch/sh/kernel/machvec.o] Error 1 make[3]: * Waiting for unfinished jobs.... /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S: Assembler messages: /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S:85: Warning: overflow in branch to __restore_all; converted into longer instruction sequence /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S:357: Warning: overflow in branch to syscall_exit_work; converted into longer instruction sequence /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S:360: Warning: overflow in branch to syscall_exit_work; converted into longer instruction sequence In file included from /kisskb/src/arch/sh/include/asm/hw_irq.h:6, from /kisskb/src/include/linux/irq.h:594, from /kisskb/src/include/asm-generic/hardirq.h:17, from /kisskb/src/arch/sh/include/asm/hardirq.h:9, from /kisskb/src/include/linux/hardirq.h:11, from /kisskb/src/include/linux/interrupt.h:11, from /kisskb/src/include/linux/serial_core.h:13, from /kisskb/src/include/linux/serial_sci.h:6, from /kisskb/src/arch/sh/kernel/cpu/sh2/setup-sh7619.c:11: /kisskb/src/include/linux/sh_intc.h:100:63: error: division 'sizeof (void ) / sizeof (void)' does not compute the number of array elements [-Werror=sizeof-pointer-div] 100 \| #define _INTC_ARRAY(a) a, __same_type(a, NULL) ?
