I've got my hands on an Allwinner D1, is it possible to use intrinsics for rvv 0.7.1? I'd like to already test a few things in my c libraries. Are there any resources other than carefully reading the spec, that documents the differences between 0.7.1 and 1.0?
- brucehoult 3y agoThere was no work on C intrinsics yet when 0.7.1 was the current draft. That started with 0.8, if I recall correctly. I'd rather program directly in assembly language, or in inline asm, than in intrinsics anyway. They are verbose, ugly, hard to write, hard to read, and even hard to modify because things such as the LMUL are baked into every single function name. I don't know of any document that carefully shows the differences. I'd like to create one, if I had someone to pay for my time to do it.
