This repository is (quasi-)forked from Arch Linux ARM PKGBUILDs repository. The changes are to enable ARM NEON SIMD support for better performance.
See branches for ARM cores that this fork supports.
When building, also change flags in /etc/makepkg.conf to enable optimization
and tuning for native CPU: -march=native -mtune=native -mfpu=neon -O3.
Before running the application linked against the library, enable access to HW performance counters as described in FFTW docs
