Transition quicksort and selection (qselect) for all supported types
from Intel’s x86 SIMD sort to Google Highway’s VQSort/VQSelect. This
unifies the sorting backend on Highway, reduces code complexity and
dependencies, preserves performance, and this patch also enables qselect
on other architectures.
Changes
x86_simd_qsort_16bit.dispatch.cpp
.highway_qsort.hpp
to call Highway VQSort/VQSelect directly.Follow-up (part 2/2)
argsort
to Highway (requires corresponding Highway changes).
