simde VS archriscv-packages

I was curious about these libraries a few weeks ago and did some searching. Is there one that's got a clearly dominating set of users or contributors?

I don't know what a good way to compare these might be, other than perhaps activity/contributor count.

I note that SIMDe doesn't have RISC-V support yet (but it does support Loongson LoongArch):

There are still a ton of things to do to get the Debian riscv64 port going too:

SIMDe is everything you're after: https://github.com/simd-everywhere/simde

> low level code that can run on multiple hardware architectures

I thought SIMD Everywhere was a pretty interesting project for that, lets you write x86 SSE/AVX code and run it on non-x86 architectures:

> architecture-specific features such as SSE/AVX which is not portable.

I don’t have hands-on experience, but somewhere on HN I saw this: https://github.com/simd-everywhere/simde If starting a new cross-platform project today, I would try that library first, before doing the usual intrinsics.

Arch RISC-V port effort[0] is what I use, and has both firefox and chromium.

RVSpace forum also has some threads re: people testing recent Firefox releases on other distros: Javascript JIT is recent in Firefox, and helps a lot.

Yeah that's one of the use cases. IIUC Arch Linux RISC-V packages are mostly built in qemu binfmt chroots (https://archriscv.felixc.at/)

Sorry for the late response. Actually there're some useful guides inside the repo's wiki, and you can start from here: https://github.com/felixonmars/archriscv-packages/wiki/Setup...
