SDL_HINT_CPU_FEATURE_MASK - A variable that limits what CPU features are available.

HEADER FILE

Defined in SDL3/SDL_hints.h

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.
