> There are no bitmanip extensions in the core instruction set where it is needed. That's the whole idea of an extension. You may or may not include it depending on your needs. > And there are no bitmanip extensions in any existing chips RISC-V is a big project, and it is not yet complete. Some extensions are completed and some are not. The bitmanip extension is not finished yet, so it's understandable that it hasn't yet been integrated into chips. > may never be in any future chips Where did that statement come from? > The notion that basic bit manipulation primitives are an obscure optional feature is a serious problem in the RISC-V process. Bit manipulation is not an "obscure optional feature", but an "optional feature" just like the other extensions. Please explain why this is a problem? You're just blaming RISC-V without any argument there.
