Contrary to GCC, # Clang doesn't recognize any comments as implicit fall-through markings # when the -Wimplicit-fallthrough option is enabled. # # So, in order to avoid having more comments being introduced, we use # the option -Wimplicit-fallthrough=5 for GCC, which similar to Clang, # will cause a warning in case a code comment is intended to be used as # a fall-through marking. The patch for Makefile also enforces this. # # We had almost 4,000 of these issues for Clang in the beginning, and # there might be a couple more out there when building some # architectures with certain configurations. However, with the recent # fixes I think we are in good shape and it is now possible to enable # the warning for Clang" # # * tag 'Wimplicit-fallthrough-clang-5.14-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gustavoars/linux: (27 commits) # Makefile: Enable -Wimplicit-fallthrough for Clang # powerpc/smp: Fix fall-through warning for Clang # dmaengine: mpc512x: Fix fall-through warning for Clang # usb: gadget: fsl_qe_udc: Fix fall-through warning for Clang # powerpc/powernv: Fix fall-through warning for Clang # MIPS: Fix unreachable code issue # MIPS: Fix fall-through warnings for Clang # ASoC: Mediatek: MT8183: Fix fall-through warning for Clang # power: supply: Fix fall-through warnings for Clang # dmaengine: ti: k3-udma: Fix fall-through warning for Clang # s390: Fix fall-through warnings for Clang # dmaengine: ipu: Fix fall-through warning for Clang # iommu/arm-smmu-v3: Fix fall-through warning for Clang # mmc: jz4740: Fix fall-through warning for Clang # PCI: Fix fall-through warning for Clang # scsi: libsas: Fix fall-through warning for Clang # video: fbdev: Fix fall-through warning for Clang # math-emu: Fix fall-through warning # cpufreq: Fix fall-through warning for Clang # drm/msm: Fix fall-through warning in msm_gem_new_impl() # ... # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/mips-linux/bin/mips-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/mips-linux/bin/mips-linux-ld --version # < git log --format=%s --max-count=1 e9338abf0e186336022293d2e454c106761f262b # < make -s -j 48 ARCH=mips O=/kisskb/build/linus_mips-allmodconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/mips-linux/bin/mips-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # Added to kconfig CONFIG_MIPS_CPS_NS16550_BASE=0x1b0003f8 # Added to kconfig CONFIG_MIPS_CPS_NS16550_SHIFT=0 # < make -s -j 48 ARCH=mips O=/kisskb/build/linus_mips-allmodconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/mips-linux/bin/mips-linux- help # make -s -j 48 ARCH=mips O=/kisskb/build/linus_mips-allmodconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/mips-linux/bin/mips-linux- olddefconfig .config:13082:warning: override: reassigning to symbol MIPS_CPS_NS16550_SHIFT # make -s -j 48 ARCH=mips O=/kisskb/build/linus_mips-allmodconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/mips-linux/bin/mips-linux- /kisskb/src/lib/test_scanf.c: In function 'numbers_list_field_width_val_width': /kisskb/src/lib/test_scanf.c:530:1: warning: the frame size of 2144 bytes is larger than 2048 bytes [-Wframe-larger-than=] } ^ /kisskb/src/lib/test_scanf.c: In function 'numbers_list_field_width_typemax': /kisskb/src/lib/test_scanf.c:488:1: warning: the frame size of 2640 bytes is larger than 2048 bytes [-Wframe-larger-than=] } ^ /kisskb/src/lib/test_scanf.c: In function 'numbers_list': /kisskb/src/lib/test_scanf.c:437:1: warning: the frame size of 2144 bytes is larger than 2048 bytes [-Wframe-larger-than=] } ^ In file included from /kisskb/src/arch/mips/include/asm/sibyte/sb1250.h:28, from /kisskb/src/drivers/watchdog/sb_wdog.c:58: /kisskb/src/arch/mips/include/asm/sibyte/bcm1480_scd.h:261: warning: "M_SPC_CFG_CLEAR" redefined #define M_SPC_CFG_CLEAR M_BCM1480_SPC_CFG_CLEAR In file included from /kisskb/src/arch/mips/include/asm/sibyte/sb1250.h:27, from /kisskb/src/drivers/watchdog/sb_wdog.c:58: /kisskb/src/arch/mips/include/asm/sibyte/sb1250_scd.h:392: note: this is the location of the previous definition #define M_SPC_CFG_CLEAR _SB_MAKEMASK1(32) In file included from /kisskb/src/arch/mips/include/asm/sibyte/sb1250.h:28, from /kisskb/src/drivers/watchdog/sb_wdog.c:58: /kisskb/src/arch/mips/include/asm/sibyte/bcm1480_scd.h:262: warning: "M_SPC_CFG_ENABLE" redefined #define M_SPC_CFG_ENABLE M_BCM1480_SPC_CFG_ENABLE In file included from /kisskb/src/arch/mips/include/asm/sibyte/sb1250.h:27, from /kisskb/src/drivers/watchdog/sb_wdog.c:58: /kisskb/src/arch/mips/include/asm/sibyte/sb1250_scd.h:393: note: this is the location of the previous definition #define M_SPC_CFG_ENABLE _SB_MAKEMASK1(33) /kisskb/src/drivers/input/joystick/analog.c:160:2: warning: #warning Precise timer not defined for this architecture.
