Detailed Description

This file provides CPU features detection.

Macro Definition Documentation

◆ HAVE_FPU

#define HAVE_FPU 0

Are single precision floating point operations "fast"? If this preprocessor constant is zero, floating point should be avoided (especially relevant for audio codecs).

Function Documentation

◆ vlc_CPU()

unsigned vlc_CPU ( void )

Retrieves CPU capability flags.

References unlikely, and vlc_CPU_raw().

◆ vlc_CPU_raw()

unsigned vlc_CPU_raw ( void )

Computes CPU capability flags.

Do not call this function directly. Call vlc_CPU() instead, which caches the correct value.
