[PATCH] D121376: [RISCV][RVV] Introduce roundmode operand to PseudoVAADD instruction

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

Having RISCVVXRMRegister work per-basic-block is fine for now, but you probably want the capability to hoist the operations out of loops at some point.

Do you have any plan for the vxsat bit?  You might want the intrinsics to take it as an explicit argument/return value.  Or maybe if you don't expect users of the intrinsics to use the bit, you could just preserve it; instead of saving/restoring vxrm, just save/restore all of vcsr.
