LoopVectorization.jl will be deprecated in Julia 1.11

[minecraft2048]

LoopVectorization will be deprecated in Julia 1.11: JuliaSIMD/LoopVectorization.jl#519 because of too much maintenance burden. This is currently used in the downconverter kernels at Tracking.jl and Acquisition.jl

The @turbo and @avx macros will be replaced by @inbounds @fastmath macro, which definitely can't SIMD complex-complex multiplication, and from my experience it will make the downconverter kernels run 40x slower, to the point that I even removed the fallback version completely in my fork: JuliaGNSS/Acquisition.jl@ac096f5

Hopefully someone will make a replacement for LoopVectorization before 1.11

I see three ways out of this situation:

• Make use the sincos function directly from https://github.com/JuliaSIMD/SLEEFPirates.jl
• Make use of the fixed point sincos function that I implemented here https://github.com/JuliaGNSS/FixedPointSinCosApproximations.jl
• Or instead of calculating sincos for every point, calculate a complex phasor at the beginning and multiply that with index number of the corresponding point
