Greg Fischer 684997eb72 DeadInsertElim: Detect and DCE dead Inserts ... This adds Dead Insert Elimination to the end of the --eliminate-insert-extract pass. See the new tests for examples of code that will benefit. Essentially, this removes OpCompositeInsert instructions which are not used, either because there is no instruction which uses the value at the index it is inserted, or because a subsequent insert intercepts any such use. This code has been seen to remove significant amounts of dead code from real-life HLSL shaders being ported to Vulkan. In fact, it is needed to remove dead texture samples which cause Vulkan validation layer errors (unbound textures and samplers) if not removed . Such DCE is thus required for fxc equivalence and legalization. This analysis operates across "chains" of Inserts which can also contain Phi instructions.		2018-01-25 16:07:21 -05:00
