Support fixed size SVE

1

This PR adds fixed size SVE support to xsimd. Client must specify the vector size in compiler options to enable SVE features. E.g., `-march=armv8-a+sve -msve-vector-bits=128` Make sure the vector size...

[DISCUSSION] How to support Arm SVE

24

I'm investigating how to support Arm SVE/SVE2 [1] in xsimd. SVE vector is size agnotics. The register size (lanes) is determinted at run time, and the according C/C++ type is...

AArch64 Neon float16x4

2

As I understand, currently xsimd does not support vectors of 16-bit floats. Their support has been recently added by AVX512-FP16, but I'm particularly interested in `float16x4` of ARM Neon. What...

Hi folks! Thanks for the great library! It's a real pleasure to use and provides really fantastic performance improvements! (As you probably know :D ) I've tried to use `xsimd::bitwise_not(batch_bool)`...

Error when loading batch_bool data into a batch type [arm64] [xsimd 8.0.5]

Dear Xsimd team, I am trying to run the following code on an AppleSilicon (M1) processor. ``` xsimd::batch_bool theBoolA {false,true,false, true}; alignas(xsimd::batch::arch_type::alignment()) std::array buffer; theBoolA.store_aligned(buffer.data()); auto result = xsimd::batch::load_aligned(buffer.data()); std::cout

Compile error with xsimd on on ARM64/Apple Silicon

Here is the traceback, unfortunately I cannot share a bigger reproducible due to proprietary code, but feel free to ask for more information. The xtensor-dependent program compiles fine with xsimd...

Hiya, Have been experimenting with ways to reduce compile times in our work codebase, thought I'd try `extern template`-ing some of the `batch` and `batch_bool` instances we use so they're...
