Yes. I'm already working on it. It makes me unhappy in some of the generic parts of the code, but I think it's still a worthwhile reorganization. Last state is here: https://github.com/VcDevel/std-simd/tree/master/experimental/ bits I'll prepare a new patch. > Also all of the x86 conversion should be removed as > __builtin_convertvector is supported now. simd_x86_conversions.h is about PR85048 (and more missing optimizations). I'd prefer to implement simd_x86_conversions.h in the compiler, but I'd need some guidance. I'd like the first release of std::experimental::simd to have high performance - because that's the main reason for using it. I'd rather wait a release than taint the impression of its usefulness. > libstdc++v3 is only ever supported by the version that comes with the > compiler. Right, that's an artifact of having active users of this code. I'll clean it up.
