[PATCH] D26856: [AArch64] Introduce features that will allow only assemblersupport for neon, crypto, fp-armv8 and fullfp16.

[Tim Northover via llvm-commits]

t.p.northover added a comment.

This option seems like a near duplicate for `-mno-implicit-float` in the backend, which already works in this configuration. It differs over what happens if explicit floats are used, but we seem to produce thoroughly unsupported soft-float code at the moment, so that probably doesn't matter.

So I'd suggest changing how Clang treats `-mgeneral-regs-only` to match `-mno-implicit-float`. Then maybe deciding what that should do if someone actually uses floats.

Tim. (Also commented on bug  along similar lines).
