unrecognized command line option '-mno-unaligned-access'

[Stephen Wu]

Hi There,

I got the error message when I add the option '-mno-unaligned-access' in.

aarch64-none-elf-gcc: error: unrecognized command line option '-mno-unaligned-access'

It looks like a validation GCC option. What's the issue?

[Zhenqiang Chen (zhenqiang-chen)]

-mno-unaligned-access is a valid GCC option for some ports like ARM. But not for all. It is not enabled for aarch64 yet.

BTW, Why do you want to use this option? Do you have unaligned-access issue?

[Ramana Radhakrishnan (ramana)]

-mstrict-align has the same effect for AArch64.
