This helps the compiler to be more aggressive and do the expected optimizations to remove unused code which otherwise gets flagged on some architectures e.g. armv7l
errors like undefined reference to `bad_unaligned_access_length' Also see http://lists.infradead.org/pipermail/kexec/2009-August/003488.html Signed-off-by: Khem Raj <raj.k...@gmail.com> Cc: Andrea Adami <andrea.ad...@gmail.com> --- meta-initramfs/recipes-kernel/kexec/kexec-tools-klibc_git.bb | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/meta-initramfs/recipes-kernel/kexec/kexec-tools-klibc_git.bb b/meta-initramfs/recipes-kernel/kexec/kexec-tools-klibc_git.bb index fe34671987..25f5da48da 100644 --- a/meta-initramfs/recipes-kernel/kexec/kexec-tools-klibc_git.bb +++ b/meta-initramfs/recipes-kernel/kexec/kexec-tools-klibc_git.bb @@ -60,7 +60,7 @@ EXTRA_OECONF += "--without-zlib --without-lzma --without-xen" # fix purgatory/printf.c:2:10: fatal error: limits.h: No such file or directory # fix include/limits.h:42:10: fatal error: bitsize/limits.h: No such file or directory -COMMON_CFLAGS += "-I${STAGING_DIR_HOST}${libdir}/klibc/include -I${S}/purgatory/include" +COMMON_CFLAGS += "-O2 -I${STAGING_DIR_HOST}${libdir}/klibc/include -I${S}/purgatory/include" CFLAGS_x86_append = " ${COMMON_CFLAGS} -I${STAGING_DIR_HOST}${libdir}/klibc/include/bits32" CFLAGS_x86-64_append = " ${COMMON_CFLAGS} -I${STAGING_DIR_HOST}${libdir}/klibc/include/bits64" CFLAGS_arm_append = " ${COMMON_CFLAGS} -I${STAGING_DIR_HOST}${libdir}/klibc/include/bits32" -- 2.19.0 -- _______________________________________________ Openembedded-devel mailing list Openembedded-devel@lists.openembedded.org http://lists.openembedded.org/mailman/listinfo/openembedded-devel
