--- Comment #6 from ktkachov at gcc dot gnu.org --- (In reply to Jakub Jelinek from comment #5) > Those options don't include -fsanitize=kernel-address, so no idea where that > earlier mentioned > _GLOBAL__sub_D_65535_0___odr_asan. > __mod_cpu__cpu_feature_match_SHA1_device_table > comes from. But, even with -fsanitize=kernel-address added to the option > there is no *__odr_asan* symbol. > cpu_feature_match_SHA1 is 4 bytes long regardless of that option. Sorry, I posted the wrong command line (I was playing with different combinations). The proper command line is: aarch64-none-linux-gnu-gcc -Wp,-MD,arch/arm64/crypto/.sha1-ce-glue.o.d -nostdinc -isystem /arm/pdtl/builds/fsf-trunk.1182/installed/rhe6x86_64/aarch64-none-linux-gnu/bin/../lib/gcc/aarch64-none-linux-gnu/7.0.0/include -I./arch/arm64/include -I./arch/arm64/include/generated/uapi -I./arch/arm64/include/generated -I./include -I./arch/arm64/include/uapi -I./include/uapi -I./include/generated/uapi -include ./include/linux/kconfig.h -D__KERNEL__ -mbig-endian -Wall -Wundef -Wstrict-prototypes -Wno-trigraphs -fno-strict-aliasing -fno-common -Werror-implicit-function-declaration -Wno-format-security -std=gnu89 -fno-PIE -mgeneral-regs-only -DCONFIG_AS_LSE=1 -fno-asynchronous-unwind-tables -mpc-relative-literal-loads -fno-delete-null-pointer-checks -Wno-frame-address -O2 --param=allow-store-data-races=0 -fno-reorder-blocks -fno-ipa-cp-clone -fno-partial-inlining -fno-stack-protector -Wno-unused-but-set-variable -Wno-unused-const-variable -fno-omit-frame-pointer -fno-optimize-sibling-calls -fno-var-tracking-assignments -pg -fno-inline-functions-called-once -Wdeclaration-after-statement -Wno-pointer-sign -fno-strict-overflow -fconserve-stack -Werror=implicit-int -Werror=strict-prototypes -Werror=date-time -Werror=incompatible-pointer-types -DCC_HAVE_ASM_GOTO -fsanitize=kernel-address -fasan-shadow-offset=0xdfffff9000000000 --param asan-stack=1 --param asan-globals=1 --param asan-instrumentation-with-call-threshold=0 -fsanitize-coverage=trace-pc -DMODULE -mcmodel=large -DKBUILD_BASENAME='"sha1_ce_glue"' -DKBUILD_MODNAME='"sha1_ce"' -c which does include -fsanitize=kernel-address
