And on 64-bit architectures it causes warnings. # # Admittedly, 64-bit architectures with ISA are basically dead - I think # the only example of this is alpha, and nobody would ever use the dmascc # driver there. But hey, the fix is easy enough, the end result is # cleaner, and it's yet another configuration that now builds without # warnings. # # If somebody actually uses this driver on an alpha and this fixes it for # you, please email me. Because that is just incredibly bizarre. # # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/m68k-linux/bin/m68k-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/m68k-linux/bin/m68k-linux-ld --version # < git log --format=%s --max-count=1 bc1abb9e55cedaeac4602426f8fc83fb3a5b1c35 # < make -s -j 32 ARCH=m68k O=/kisskb/build/linus_m5272c3_defconfig_m68k-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/m68k-linux/bin/m68k-linux- m5272c3_defconfig # < make -s -j 32 ARCH=m68k O=/kisskb/build/linus_m5272c3_defconfig_m68k-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/m68k-linux/bin/m68k-linux- help # make -s -j 32 ARCH=m68k O=/kisskb/build/linus_m5272c3_defconfig_m68k-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/m68k-linux/bin/m68k-linux- olddefconfig # make -s -j 32 ARCH=m68k O=/kisskb/build/linus_m5272c3_defconfig_m68k-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/m68k-linux/bin/m68k-linux- In file included from /kisskb/src/include/linux/string.h:20, from /kisskb/src/include/linux/bitmap.h:10, from /kisskb/src/include/linux/cpumask.h:12, from /kisskb/src/include/linux/mm_types_task.h:14, from /kisskb/src/include/linux/mm_types.h:5, from /kisskb/src/include/linux/buildid.h:5, from /kisskb/src/include/linux/module.h:14, from /kisskb/src/drivers/net/ethernet/freescale/fec_main.c:25: In function 'fec_get_mac', inlined from 'fec_enet_init' at /kisskb/src/drivers/net/ethernet/freescale/fec_main.c:3510:8, inlined from 'fec_probe' at /kisskb/src/drivers/net/ethernet/freescale/fec_main.c:3932:8: /kisskb/src/arch/m68k/include/asm/string.h:72:25: warning: '__builtin_memcpy' reading 6 bytes from a region of size 0 [-Wstringop-overread] 72 \| #define memcpy(d, s, n) __builtin_memcpy(d, s, n) \| ^~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/drivers/net/ethernet/freescale/fec_main.c:1771:9: note: in expansion of macro 'memcpy' 1771 \| memcpy(ndev->dev_addr, iap, ETH_ALEN); \| ^~~~~~ Completed OK # rm -rf /kisskb/build/linus_m5272c3_defconfig_m68k-gcc11 # Build took: 0:00:20.443800
