simde VS capstone

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.

Maybe then they can help us with the Capstone[1][2] disassembly engine auto-sync (automatic synchronization from the LLVM TableGen files) effort[3]. ARMv7, ARMv8/9, PowerPC are nearly finished, and MIPS in in near-term plans. Nobody stepped in for RISC-V yet.

Bloaty is a nice tool.

When I worked on Matter a couple years ago, we had the problem that its backend http://www.capstone-engine.org/ did not support Xtensa, and produced some Python tools that could take output from bloaty or similar data from readelf or elftools, and produce several kinds of report.
