Preliminary work of mine can be found here: https://github.com/jrlanglois/JUCE/commit/969690ba5a7c64426db34f3635248c37c33dd5cd
Edit: Well, this is now redundant to FR: Pull Request - Add FMA3 and FMA4 instruction detection, and improved Linux information support .
I suppose this is from the GitHub issues which are being copied into the forum… @t0m @ed95 ?
