Support for func calls with SVE fixed length vector argument

[v01dXYZ]

Hello,

What is the current support of function calls with fixed length vector arguments when SVE is used for fixed length vectors (AArch64TargetLowering::useSVEForFixedLengthVectorVT) ?

It doesn't seem supported at all, as the calling convention tablegen file seems to only mention 128b vector types.

Are github issues the right way to ask question ? Is there a better channel for that ?

https://discourse.llvm.org is better place for questions.
