That definetly doesn't apply to unrolling. In eve the ability to zip ranges is fundamental and is very important

Thanks for this example. Can you write the second one two? With two ranges? That's where I believe the variadics will be. FYI: The codegen is smaller because the loop is not unrolled. That's a 2x slower on my measurements. + at le

I don't think this works if your files are modules. Let's stop here, it doesn't seem like we understand each other.

Well. You have a file, something like: load.h You need to include it multiple times, compiled with different flags. So - it's never going to be in load.cxx or whatever that's called.

> is to re-include our source file Yeah - that means your source file is never a module. We would really like eve to be modularized, the CI times are unbearable. I'd love to be proven wrong here, that'd be amazing. But I don&#x

cppcast talked about soagen https://cppcast.com/soagen/ I didn't look into it too much.

I struggle to read the highway documentation, it focuses on things that are unrelated to me. So sorry if I'm wrong. Let me write the std::ranges code and ask you to write them with highway. https://godbolt.org/z/3s

I don't think we understand each other. We want to take one function and compile it twice: ``` namespace MEGA_MACRO { void foo(std::span<int> s) { super_awesome_platform_specific_thing(s); } } // namespace MEGA_MACRO

The algorithms I tried to make as good as I knew how. Maybe 95% there. Nice tail handling. A lot of things supported. I like or interface over other alternatives, but I'm biased here. Really massive math library.

You can do many thing with macros and inline namespaces but I believe they run into problems when modules come into play. Can you compile the same code twice, with different flags with modules?

FYI: You don't want to do this. `supports<avx512>` is an expensive check. You really want to put this check in a static.

Hi! Thanks for your interest in the library. Here is a godbolt example: https://godbolt.org/z/bEGd7Tnb3 Here is a bunch of simple examples: https://github.com/jfalcou/eve/blob/fb093a0553d

AMD we support pretty well. I tested Zen1 and a bit Zen4

Our answer to this - is dynamic dispatch. If you want to have multiple version of the same kernel compiled - compile multiple dlls. The big problem here is: ODR violations. We really didn't want to do the xsimd thing of forcing the use
