Synopsis
#include "SDL3/SDL.h" #define SDL_HINT_CPU_FEATURE_MASK SDL_CPU_FEATURE_MASK"
Description
By default, SDL marks all features the current CPU supports as available. This hint allows to limit these to a subset.
When the hint is unset, or empty, SDL will enable all detected CPU features.
The variable can be set to a comma separated list containing the following items:
· "all"
· "altivec"
· "sse"
· "sse2"
· "sse3"
· "sse41"
· "sse42"
· "avx"
· "avx2"
· "avx512f"
· "arm-simd"
· "neon"
· "lsx"
· "lasx"
The items can be prefixed by '+'/'-' to add/remove features.
Availability
This hint is available since SDL 3.2.0.
