Double Precision Support For RadeonSI Driver

Double precision support is to be merged into the AMD LLVM back-end for the Radeon HD 7000 "RadeonSI" graphics cards on the open-source Linux graphics driver.

Niels Ole Salscheider, an independent open-source contributor, sent in a set of six patches last week to provide RadeonSI double precision support. These patches go against the R600 GPU LLVM back-end for those needing double precision support.

An updated patch-set were sent on Tuesday and AMD's Tom Stellard has said he will pull in this support for the AMD GPU LLVM back-end. A simple patch is also needed against Mesa's Gallium3D "Clover" OpenCL state tracker for allowing double precision operations.
