Hi, this series was originally motivated by fixing a VM fault and ended up growing a bit larger :-)
The goal of patches 1-7 is to change st/mesa so that it sets the UsageMask field in temporary array declarations. This ends up being helpful for lowering float and vecN arrays with N <= 3. The remaining patches are radeon (really radeonsi) specific. They begin with a bunch of cleanups, and then do two things: first, when alloca is used for arrays, make use of the UsageMask to allocate smaller arrays when possible. Second, add explicit bounds checks when accessing those arrays to prevent VM faults -- those temporary array accesses are not protected by limits in buffer descriptors. Note that the radeon part of the series exposes some pre-existing LLVM bugs in Piglit, at least one of which has already been encountered elsewhere, see http://reviews.llvm.org/D22556 and http://reviews.llvm.org/D23303. Please review! Thanks, Nicolai _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
