Neon is a mandatory part of the ARMv8 architecture, unlike ARMv7, where it?s optional. > As I understand, your statement for ARMv8 is true for AAarch64 mode. But for ARMv8 in AAarch32 mode, neon is still optional (although I haven't heard of an implementation that does not support NEON even in AAarch32 mode). So, for AArch64 mode, I think rtcd can be disabled. Also, even the neon detection procedure currently in opus will not work on ARMv8 AArch32 mode. Please refer > htt...

...ready there in the project before this patch. I just re-used the infrastructure. ARMv8 shouldn?t need Neon detection at all ? Neon is a mandatory part of the ARMv8 architecture, unlike ARMv7, where it?s optional. As I understand, your statement for ARMv8 is true for AAarch64 mode. But for ARMv8 in AAarch32 mode, neon is still optional (although I haven't heard of an implementation that does not support NEON even in AAarch32 mode).
