That can # be seen in the output above, the only flag passed to the compiler is # -Wno-error. # # Fix it by dropping the conditional setting of CFLAGS in flags.mk. # Instead always set CFLAGS, but also append USERCFLAGS if they are set. # # Note that appending to CFLAGS (with +=) wouldn't work, because flags.mk # is included by multiple Makefiles (to support partial builds), causing # CFLAGS to be appended to multiple times. Additionally that would place # the USERCFLAGS prior to the standard CFLAGS, meaning the USERCFLAGS # couldn't override the standard flags. Being able to override the # standard flags is desirable, for example for adding -Wno-error. # # With the fix in place, the CFLAGS are set correctly, including the # USERCFLAGS: # # $ make -C tools/testing/selftests/powerpc V=1 USERCFLAGS=-Wno-error # ... # gcc -std=gnu99 -O2 -Wall -Werror -DGIT_VERSION='"v6.10-rc2-7-gdea17e7e56c3"' # -I/home/michael/linux/tools/testing/selftests/powerpc/include -Wno-error # cache_shape.c ... # # Fixes: 5553a79387e9 ("selftests/powerpc: Add flags.mk to support pmu buildable") # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://msgid.link/20240706120833.909853-1-mpe@ellerman.id.au # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 8b7f59de92ac65aa21c7d779274dbfa577ae2d2c # make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-fixes_44x_sam440ep_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 44x/sam440ep_defconfig # < make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-fixes_44x_sam440ep_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-fixes_44x_sam440ep_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-fixes_44x_sam440ep_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/arch/powerpc/boot/dts/sam440ep.dts:266.22-287.5: Warning (interrupt_provider): /plb/pci@ec000000: '#interrupt-cells' found, but node is not an interrupt provider arch/powerpc/boot/dts/sam440ep.dtb: Warning (interrupt_map): Failed prerequisite 'interrupt_provider' Completed OK # rm -rf /kisskb/build/powerpc-fixes_44x_sam440ep_defconfig_powerpc-gcc5 # Build took: 0:00:36.720560
