Oh, and for posterity, strfllw in #winehackers tracked down the original thread from 2017: https://lists.freedesktop.org/archives/mesa-dev/2017-January/140613.html Not sure how I missed it, I even looked in Jan 2017, but there we are. Apparently part of the difficulty for radeonsi is LLVM, but perhaps ACO could soften some of that blow. -ilia _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
