I think you should look more here: https://releases.linaro.org/components/toolchain/binaries/7.4-2019.02/ http://releases.linaro.org/components/toolchain/gcc-linaro/7.4-2019.02/ To my knowledge, they are the ones who are most responsible for support for aarch64. > The issue is for lower level code that can't be written in C, for > example making system calls.

QBE should also emit asm for noexecstack by adding (for GNU as): .section .note.GNU-stack,"",%progbits more info: https://wiki.gentoo.org/wiki/Hardened/GNU_stack_quickstart Daniel
