If-statements are not affected because removing flow control can cause the i965 instrution scheduler to create some very long live ranges resulting in unncessary spilling. This causes some shaders to fall of a performance cliff. Since many small if-statements are already flattened to bcsel, this optimization covers more than 68% of the possible cases (2417 shaders helped for instructions on Skylake vs. 3554). v2: Reorder and add whitespace to make the relationship between the patterns more obvious.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most integer operations are omitted because dealing with integer overflow is hard. There are a few things that could be smarter if there was a small amount more tracking of ranges of integer types (i.e., operands are Boolean, operand values fit in 16 bits, etc.). The changes to nir_search_helpers.h are included in this patch to simplify reordering the changes to nir_opt_algebraic.py. v2: Memoize range analysis results. Without this, some shaders appear to get stuck in infinite loops. v3: Rebase on many months of Mesa changes, including 1-bit Boolean changes. v4: Rebase on "nir: Drop imov/fmov in favor of one mov instruction". v5: Use nir_alu_srcs_equal for detecting (a*a). Previously just the SSA value was compared, and this incorrectly matched (a.x*a.y). v6: Many code improvements including (but not limited to) better names, more comments, and better use of helper functions. All suggested by Caio. Rework the handling of several opcodes to use a table for mapping source ranges to a result range. This change fixed a bug that caused fmax(gt_zero, ge_zero) to be incorrectly recognized as ge_zero. Slightly tighten the range of fmul by recognizing that x*x is gt_zero if x is gt_zero. Add similar handling for -x*x. v7: Use _______ in the tables as an alias for unknown. Suggested by Caio. Reviewed-by: Caio Marcelo de Oliveira Filho <[email protected]>
