There is, please see [1]. The vector register file handling is missing right now as I’m not sure if we have agreed upon a calling convention for RVV. In the spec, I have already specified the interaction with RVV: > Any other registers are callee-saved. This includes any vector registers when the vector extension is supported. Once the calling convention is decided, I will add saving of all caller-saved registers into the TLSDESC stub.
