--- Comment #4 from Dave Witbrodt dawitbro@sbcglobal.net --- Emil's patch (now applied in Mesa 9.2.0-devel), along with an LLVM 3.5 build with the proper symlinks (bug 75919), nearly allows me to build Mesa for RadeonSI. In my scrambling about to get the build working again, I forgot that I also had to apply a patch from bug 70410 to get the build working.
Anyway, glad to see this bug closed.
