--- Comment #8 from rrorden at ptc dot com ---
So the proposal is to add an aarch64 linker option that places stubs after
input sections that need them, just like aarch32, and I would need to implement
the -ffunction-sections behavior in our aot compiler so each function (and they
are relatively small) gets a unique section name. The A53 erratum would not
force every stub section to align to 4k, but that is a worst-case scenario. If
this is correct, I am okay with it.

How does the linker know it is targeting an A53 core? I see ld options
--fix-cortex-a53-835769, --fix-cortex-a53-843419. Do these need to be set
explicitly?
