This series add support for partial loop unrolling for loops with an unknown trip count. The new partial_unroll function allows the caller to specifiy how may times the loop should be unrolled and then the loop is inserted in the innermost continue branch of the unrolled loop.
For now we only do partial unrolling for loops where we can guess the iteration count based on array access that uses an induction variable as its index (see patch 7). Patches 1-6 are tidy-ups/refactors. Patch 7 adds a method for guessing the trip count for the loop. Patch 8 adds partial unrolling support and also support for removing redundant load/stores from the remaining loop when considering if we would be accessing an array out bounds. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
