In my experience, most libraries have C fallback for x64 assembly, if not another handrolled NEON assembly. I would like to know which libraries have x64 assembly without C fallback.
- tatersolid 7y agoI’m sure most have C fallback, but that code is 20x slower and isn’t actually tested or used by anybody else in practice. The devs probably don’t even have unit tests or build environments for ARM server platforms. As for which libraries, I’m too lazy to do a detailed search. All I can report anecdotally is that we very briefly tried ARM at dayjob on our codebase about a year ago and it seemed everything was immediately broken. Especially interop between high level languages and C libraries. The team tasked with it said almost imm fiat would “way too hard, let’s quit this experiment”.
