Fixing GCC Intrinsics: Highlighting a blindspot with a big Neon sign

Compiler intrinsics are often used to write high performance SIMD code for DSP applications such image and video codecs. In this presentation we'll share how we improved GCC's AArch64 backend implementation of Neon SIMD intrinsics to unlock significant gains in real-world application performance.
