Yes, using cortex-strings as the bridge is indeed the preferred way. I am
asking which strategy do you see:
- Adding ifunc variants and add them as default if system advertise SVE
support.
- Or adding as an extra option (as Szabolcs has proposed sometime ago
for LSE), where one would need to build and extra glibc library and
loader will select it if the case.
