This is reproducible for me locally with: $ make -skj"$(nproc)" ARCH=arm64 CC=clang CROSS_COMPILE=aarch64-linux-gnu- HOSTCC=clang LD=ld.lld clean allnoconfig all aarch64-linux-gnu-objcopy: vmlinux: file format not recognized ... This does not occur with llvm-objcopy via LLVM=1 nor does it happen with an all GNU setup. This feels like a bug in GNU objcopy though, as this is reproducible with: $ aarch64-linux-gnu-objcopy --set-section-flags .modinfo=noload vmlinux.unstripped vmlinux.objcopy $ file vmlinux.unstripped vmlinux.objcopy vmlinux.unstripped: ELF 64-bit LSB pie executable, ARM aarch64, version 1 (SYSV), statically linked, BuildID[sha1]=18512f67dae70a7fae145b34514054a8b8b3c105, not stripped vmlinux.objcopy: ELF 64-bit LSB pie executable, ARM aarch64, version 1 (SYSV), statically linked, BuildID[sha1]=18512f67dae70a7fae145b34514054a8b8b3c105, not stripped $ aarch64-linux-gnu-objcopy --remove-section=.modinfo -w --strip-unneeded-symbol='__mod_device_table__*' vmlinux.objcopy aarch64-linux-gnu-objcopy: vmlinux.objcopy: file format not recognized $ aarch64-linux-gnu-objcopy --version | head -1 GNU objcopy (GNU Binutils) 2.45.50.20251028 Cheers, Nathan _______________________________________________ linaro-toolchain mailing list -- [email protected] To unsubscribe send an email to [email protected]
