This works well if you configure # and build the kernel on the same host machine. # # It is inconvenient if you prepare the .config that is carried to a # different build environment (typically this happens when you package # the kernel for distros) because using a different compiler potentially # produces different CONFIG options than the real build environment. # So, you probably want to make as many options visible as possible. # In other words, you need to create a super-set of CONFIG options that # cover any build environment. If some of the CONFIG options turned out # to be unsupported on the build machine, they are automatically disabled # by the nature of Kconfig. # # However, it is not feasible to get a full-featured compiler for every # arch. # # This issue was discussed here: # # https://lkml.org/lkml/2019/12/9/620 # # Other than distros, savedefconfig is also a problem. Some arch sub-systems # periodically resync defconfig files. If you use a less-capable compiler # for savedefconfig, options that do not meet 'depends on $(cc-option,...)' # will be forcibly disabled. So, 'make defconfig && make savedefconfig' # may silently change the behavior. # # This commit adds a set of dummy toolchains that pretend to support any # feature. # # Most of compiler features are tested by cc-option, which simply checks # the exit code of $(CC). The dummy tools are shell scripts that always # exit with 0. So, $(cc-option, ...) is evaluated as 'y'. # # There are more complicated checks such as: # # scripts/gcc-x86_{32,64}-has-stack-protector.sh # scripts/gcc-plugin.sh # scripts/tools-support-relr.sh # # scripts/dummy-tools/gcc passes all checks. # # From the top directory of the source tree, you can do: # # $ make CROSS_COMPILE=scripts/dummy-tools/ oldconfig # # Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> # Reviewed-by: Philipp Rudo <prudo@linux.ibm.com> # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/m68k-linux/bin/m68k-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/m68k-linux/bin/m68k-linux-ld --version # < git log --format=%s --max-count=1 21466c8b8fbaaec5c54d1f8565657dc2f6b25583 # < make -s -j 24 ARCH=m68k O=/kisskb/build/kbuild_m68k-defconfig_m68k-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/m68k-linux/bin/m68k-linux- defconfig # < make -s -j 24 ARCH=m68k O=/kisskb/build/kbuild_m68k-defconfig_m68k-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/m68k-linux/bin/m68k-linux- help # make -s -j 24 ARCH=m68k O=/kisskb/build/kbuild_m68k-defconfig_m68k-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/m68k-linux/bin/m68k-linux- olddefconfig # make -s -j 24 ARCH=m68k O=/kisskb/build/kbuild_m68k-defconfig_m68k-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/m68k-linux/bin/m68k-linux- /kisskb/src/scripts/Makefile.asm-generic:25: redundant generic-y found in arch/m68k/include/asm/Kbuild: hardirq.h In file included from /kisskb/src/arch/m68k/include/asm/amigayle.h:21, from /kisskb/src/arch/m68k/include/asm/io_mm.h:59, from /kisskb/src/arch/m68k/include/asm/io.h:8, from /kisskb/src/include/linux/clocksource.h:21, from /kisskb/src/arch/m68k/amiga/config.c:20: /kisskb/src/arch/m68k/amiga/config.c: In function 'amiga_identify': /kisskb/src/arch/m68k/include/asm/amigahw.h:42:50: warning: this statement may fall through [-Wimplicit-fallthrough=] #define AMIGAHW_SET(name) (amiga_hw_present.name = 1) ~~~~~~~~~~~~~~~~~~~~~~~^~~~ /kisskb/src/arch/m68k/amiga/config.c:223:3: note: in expansion of macro 'AMIGAHW_SET' AMIGAHW_SET(PCMCIA); ^~~~~~~~~~~ /kisskb/src/arch/m68k/amiga/config.c:224:2: note: here case AMI_500: ^~~~ /kisskb/src/arch/m68k/mvme147/config.c: In function 'mvme147_hwclk': /kisskb/src/arch/m68k/mvme147/config.c:175:2: warning: #warning check me!
