We’ll see that a well designed function API can have an even larger impact.How will we compare performance? ● Benchmarks at this low level are how machine code is generated from C++ System V gABI psABI: ARM, x86, … C++ Itanium ABI Microsoft Windows ABIs C++ Standard 18armv8-a System V ABI - iPhone - M1 Mac and newer - Android smartphone x86-64 (AMD64) Microsoft ABI - Windows device armv7-a System V ABI - ancient iPhone - low-end Android smartphone x86 (IA-32) System V ABI - ancient Linux server x86 (IA-32) Microsoft ABI - ancient
