The article discusses using lookup tables to efficiently convert enums to strings, noting that naive switch-case implementations produce poor assembly at low optimization levels. Modern GCC at -O2 and above automatically rewrites such switch statements into compact lookup tables, improving performance significantly.
Background
The article originates from corsix.org, a blog by a game developer/programmer, published October 21, 2026. It covers a common C programming pattern where enum-to-string conversion is needed, typically in graphics APIs like DirectX DXGI format naming.
