vector intrinsics for both RV32/RV64

Guy Lemieux


I’m starting a project where we want to use vector intrinsics and generate both 64b and 32b code (for RV64 and RV32).

It looks line the best way to do this right now is with GCC, where we were able to find up-to-date intrinsics for the v0.10 spec:

Is there a similar ability with LLVM? Vector support seems to be added, but no up to date intrinsics yet. This is the closest I could find, but it appears to be a bit out of date (vector spec 0.8) and only for RV32:

Sorry if this is an obvious question — I haven’t dug very deeply into this yet, but I thought this group would be able to give me better answers and save me a bit of time.

Thanks for any pointers.
