Cray 1 Supercomputer Performance Comparisons With Home Computers Phones and Tablets
CPU architectures often gain interesting new instructions as they evolve, but application developers often find it difficult to take advantage of those instructions. Reluctance to lose backward-compatibility is one of the main roadblocks slowing developers from using advancements in newer computing architectures. Function multi-versioning (FMV), which first appeared in GCC 4.8, is a way to have multiple implementations of a function, each using a different architecture's specialized instruction-set extensions. GCC 6 introduces changes to FMV that make it even easier to bring architecture-b...
