That way ie is # available regardless of math-emulation. # # Signed-off-by: Linus Torvalds # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 d4d016caa4b85b9aa98d7ec8c84e928621a614bc # < make -s -j 80 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux- randconfig # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # Added to kconfig CONFIG_CC_STACKPROTECTOR_STRONG=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_GCC_PLUGIN_CYC_COMPLEXITY=n # Added to kconfig CONFIG_GCC_PLUGIN_SANCOV=n # Added to kconfig CONFIG_GCC_PLUGIN_LATENT_ENTROPY=n # Added to kconfig CONFIG_BPF_PRELOAD=n # Added to kconfig # < make -s -j 80 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux- help # make -s -j 80 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux- olddefconfig .config:4990:warning: override: reassigning to symbol PREVENT_FIRMWARE_BUILD .config:4992:warning: override: reassigning to symbol GCC_PLUGINS .config:4996:warning: override: reassigning to symbol BPF_PRELOAD # make -s -j 80 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux- /kisskb/src/kernel/kcsan/kcsan_test.c: In function 'test_atomic_builtins': /kisskb/src/kernel/kcsan/kcsan_test.c:953:17: warning: 'atomic_thread_fence' is not supported with '-fsanitize=thread' [-Wtsan] 953 | __atomic_thread_fence(__ATOMIC_SEQ_CST); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ arch/x86/crypto/sm4-aesni-avx-asm_64.o: warning: objtool: sm4_aesni_avx_crypt8()+0x8: sibling call from callable instruction with modified stack frame lib/strncpy_from_user.o: warning: objtool: strncpy_from_user()+0x31a: call to do_strncpy_from_user() with UACCESS enabled lib/strnlen_user.o: warning: objtool: strnlen_user()+0x29e: call to do_strnlen_user() with UACCESS enabled vmlinux.o: warning: objtool: .altinstructions+0x1464: don't know how to handle non-section reloc symbol arch_stack_walk Completed OK # rm -rf /kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc11 # Build took: 0:06:47.502209
