Product: SDL Reporter: Haneef Mubarak <haneef503>

Status: RESOLVED FIXED QA Contact: Sam Lantinga <slouken>

Description Haneef Mubarak 2014-02-02 01:26:23 UTC 
AVX is the successor to SSE* and is fairly widely available. As such, it really ought to be detectable.

This functionality ought to be trivial to implement, and not having it means being forced to write an ugly workaround to check for AVX (so that normal SSE can be used if AVX is not available).

Here is an example on detecting AVX from SO (it actually shows ways to cehck for all of teh fancy instructions):
