AMD Drops Steamroller "bdver3" Compiler Support


Second-generation Bulldozer processors only started appearing recently in the form of the Trinity APUs with Piledriver cores. The next Bulldozer-2 wave will come when AMD releases their Piledriver-bearing "Vishera" FX-Series desktop processors. While this hardware has yet to publicly arrive, AMD is are already working on compiler support for their third-generation Bulldozer -- a.k.a. "Steamroller" -- micro-architecture.

As first spotted via my Anzwix system, Ganesh Gopalasubramanian of AMD published the first patch work concerning "bdver3" enablement to gcc-patches on Thursday morning. "The attached patch (Patch.txt) enables the next version of AMD's bulldozer core. A new file (bdver3.md) is also attached which describes the pipelines."

As with previous generations, this compiler tuning/optimization support for next year's AMD hardware is being called "bdver3" in a similar naming convention to the original Bulldozer CPUs ("bdver1") and the new Piledriver / Bulldozer 2 support ("bdver3"). The bdver3 GCC patch in its early form copies most of the tuning work from bdver2 but the pipelines have already been modelled after the new Steamroller core.
