WebJan 8, 2013 · Intrinsics Intrinsics are functions which are separately handled by the compiler. These functions are often optimized to perform in the most efficient ways possible and hence run faster than normal implementations. However, since these functions depend on the compiler, it makes it difficult to write portable applications.

NEON code generated by GCC¶ The GCC option -ftree-vectorize (implied by -O3) tries to exploit implicit parallelism, and generates NEON code from ordinary C source code. This is fully supported as long as the rules above are followed. NEON intrinsics¶
WebSIMD Everywhere. The SIMDe header-only library provides fast, portable implementations of SIMD intrinsics on hardware which doesn't natively support them, such as calling SSE functions on ARM. There is no performance penalty if the hardware supports the native implementation (e.g., SSE/AVX runs at full speed on x86, NEON on ARM, etc.).This makes …
