But that seems to have been fixed somewhere in the interim. # # So move the -Werror addition to the top-level of the arch, this saves # us from repeating it in every Makefile and means we won't forget to # add it to any new sub-dirs. # # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < git log --format=%s --max-count=1 265e51be6d27250edf42e9045db287b406897873 # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc64le_allmodconfig_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc64le_allmodconfig # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc64le_allmodconfig_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/scripts/unifdef.c: In function 'Mpass': /kisskb/src/scripts/unifdef.c:453:28: warning: 'strncpy' output truncated before terminating nul copying 4 bytes from a string of the same length [-Wstringop-truncation] static void Mpass (void) { strncpy(keyword, "if ", 4); Pelif(); } ^~~~~~~~~~~~~~~~~~~~~~~~~~~ In file included from /kisskb/src/arch/powerpc/include/asm/paca.h:19, from /kisskb/src/arch/powerpc/include/asm/current.h:16, from /kisskb/src/include/linux/sched.h:12, from /kisskb/src/kernel/debug/kdb/kdb_support.c:15: In function 'strncpy', inlined from 'kallsyms_symbol_next' at /kisskb/src/kernel/debug/kdb/kdb_support.c:239:4: /kisskb/src/include/linux/string.h:246:9: warning: '__builtin_strncpy' specified bound depends on the length of the source argument [-Wstringop-overflow=] return __builtin_strncpy(p, q, size); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/kernel/debug/kdb/kdb_support.c: In function 'kallsyms_symbol_next': /kisskb/src/include/linux/string.h:267:10: note: length computed here return __builtin_strlen(p); ^~~~~~~~~~~~~~~~~~~ /kisskb/src/arch/powerpc/platforms/pseries/hotplug-memory.c: In function 'dlpar_memory': /kisskb/src/arch/powerpc/platforms/pseries/hotplug-memory.c:962:5: warning: 'rc' may be used uninitialized in this function [-Wmaybe-uninitialized] if (!rc) { ^ In file included from /kisskb/src/arch/powerpc/include/asm/paca.h:19, from /kisskb/src/arch/powerpc/include/asm/hw_irq.h:64, from /kisskb/src/arch/powerpc/include/asm/irqflags.h:12, from /kisskb/src/include/linux/irqflags.h:16, from /kisskb/src/include/linux/spinlock.h:54, from /kisskb/src/include/linux/seqlock.h:36, from /kisskb/src/include/linux/time.h:6, from /kisskb/src/include/linux/stat.h:19, from /kisskb/src/include/linux/module.h:10, from /kisskb/src/lib/test_hexdump.c:8: In function 'strncpy', inlined from 'test_hexdump_prepare_test.isra.0' at /kisskb/src/lib/test_hexdump.c:102:3: /kisskb/src/include/linux/string.h:246:9: warning: '__builtin_strncpy' specified bound depends on the length of the source argument [-Wstringop-overflow=] return __builtin_strncpy(p, q, size); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/lib/test_hexdump.c: In function 'test_hexdump_prepare_test.isra.0': /kisskb/src/include/linux/string.h:267:10: note: length computed here return __builtin_strlen(p); ^~~~~~~~~~~~~~~~~~~ /kisskb/src/drivers/scsi/esas2r/esas2r_ioctl.c: In function 'esas2r_write_vda': /kisskb/src/drivers/scsi/esas2r/esas2r_ioctl.c:1910:19: warning: 'dma_addr' may be used uninitialized in this function [-Wmaybe-uninitialized] a->ppvda_buffer = dma_addr; ~~~~~~~~~~~~~~~~^~~~~~~~~~ In file included from /kisskb/src/arch/powerpc/include/asm/paca.h:19, from /kisskb/src/arch/powerpc/include/asm/hw_irq.h:64, from /kisskb/src/arch/powerpc/include/asm/irqflags.h:12, from /kisskb/src/include/linux/irqflags.h:16, from /kisskb/src/include/linux/spinlock.h:54, from /kisskb/src/include/linux/seqlock.h:36, from /kisskb/src/include/linux/time.h:6, from /kisskb/src/include/linux/stat.h:19, from /kisskb/src/include/linux/module.h:10, from /kisskb/src/drivers/scsi/ibmvscsi_tgt/ibmvscsi_tgt.c:27: In function 'strncat', inlined from 'ibmvscsis_probe' at /kisskb/src/drivers/scsi/ibmvscsi_tgt/ibmvscsi_tgt.c:3478:2: /kisskb/src/include/linux/string.h:313:10: warning: '__builtin_strncat' specified bound 64 equals destination size [-Wstringop-overflow=] return __builtin_strncat(p, q, count); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ WARNING: vmlinux.o(.text+0x35c4): Section mismatch in reference from the variable __boot_from_prom to the function .init.text:prom_init() The function __boot_from_prom() references the function __init prom_init().
