* glsl: Make lower_constant_arrays_to_uniforms require dereferences.Kenneth Graunke2014-11-241-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ilia noticed that my lowering pass was converting the constant array used by textureGatherOffsets' offsets parameter to a uniform. This broke textureGather for Nouveau, and is generally a horrible plan, since it violates the GLSL constraint that offsets must be an immediate constant. When I wrote this pass, I neglected to consider whole array assignment. I figured opt_array_splitting would handle constant indexing, so this pass was really about fixing variable indexing. textureGatherOffsets is an example of whole array access that we really don't want to touch. Whole array copies don't appear to benefit from this either - they're most likely initializers for temporary arrays which are going to be mutated anyway. Since you're copying, you may as well copy from immediates, not uniforms. This patch makes the pass look for ir_dereference_arrays of ir_constants, rather than looking for any ir_constant directly. This way, it ignores whole array assignment. No shader-db changes or Piglit regressions on Haswell. Some Piglit tests generate different code (fixing textureGatherOffsets on Nouveau).

* glsl: Skip loop-too-large heuristic if indexing arrays of a certain sizeKenneth Graunke2014-11-061-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A pattern in certain shaders is: uniform vec4 colors[NUM_LIGHTS]; for (int i = 0; i < NUM_LIGHTS; i++) { ...use colors[i]... } In this case, the application author expects the shader compiler to unroll the loop. By doing so, it replaces variable indexing of the array with constant indexing, which is more efficient. This patch extends the heuristic to see if arrays accessed within the loop are indexed by an induction variable, and if the array size exactly matches the number of loop iterations. If so, the application author probably intended us to unroll it. If not, we rely on the existing loop-too-large heuristic. Improves performance in a phong shading microbenchmark by 2.88x, and a shadow mapping microbenchmark by 1.63x. Without variable indexing, we can upload the small uniform arrays as push constants instead of pull constants, avoiding shader memory access. Affects several games, but doesn't appear to impact their performance.

* glsl: Lower constant arrays to uniform arrays.Kenneth Graunke2014-11-064-0/+106
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Consider GLSL code such as: const ivec2 offsets[] = ivec2[](ivec2(-1, -1), ivec2(-1, 0), ivec2(-1, 1), ivec2(0, -1), ivec2(0, 0), ivec2(0, 1), ivec2(1, -1), ivec2(1, 0), ivec2(1, 1)); ivec2 offset = offsets[<non-constant expression>]; Both i965 and nv50 currently handle this very poorly. On i965, this becomes a pile of MOVs to load the immediate constants into registers, a pile of scratch writes to move the whole array to memory, and one scratch read to actually access the value - effectively the same as if it were a non-constant array. We'd much rather upload large blocks of constant data as uniform data, so drivers can simply upload the data via constbufs, and not have to populate it via shader instructions. This is currently non-optional because both i965 and nouveau benefit from it, and according to Marek radeonsi would benefit today as well. (According to Tom, radeonsi may want to handle this itself in the long term, but we can always add a flag when it becomes useful.)

This new implementation uses an 11th degree polynomial to approximate atan in the [-1..1] range, and the following identitiy to reduce the entire range to [-1..1]: atan(x) = 0.5 * pi * sign(x) - atan(1.0 / x) This range-reduction idea is taken from the paper "Fast computation of Arctangent Functions for Embedded Applications: A Comparative Analysis" (Ukil et al. 2011). The polynomial that approximates atan(x) is: x * 0.9999793128310355 - x^3 * 0.3326756418091246 + x^5 * 0.1938924977115610 - x^7 * 0.1173503194786851 + x^9 * 0.0536813784310406 - x^11 * 0.0121323213173444 This polynomial was found with the following GNU Octave script: x = linspace(0, 1); y = atan(x); n = [1, 3, 5, 7, 9, 11]; format long; polyfitc(x, y, n) The polyfitc function is not built-in, but too long to include here.

The algorithm is similar to alpha-beta pruning on a minmax search, from the field of AI. This optimization pass can optimize min/max expressions where operands are min/max expressions. Such code can appear in shaders by itself, or as the result of clamp() or AMD_shader_trinary_minmax functions. This optimization pass improves the generated code for piglit's AMD_shader_trinary_minmax tests as follows: total instructions in shared programs: 75 -> 67 (-10.67%) instructions in affected programs: 60 -> 52 (-13.33%) GAINED: 0 LOST: 0 All tests (max3, min3, mid3) improved.

Version 2 by Iago Toral Quiroga <[email protected]>: Changes from review feedback: - Squashed various cosmetic changes sent by Matt Turner. - Make less_all_components return an enum rather than setting a class member. (Suggested by Mat Turner). Also, renamed it to compare_components. - Make less_all_components, smaller_constant and larger_constant static. (Suggested by Mat Turner) - Change mixmax_range to call its limits "low" and "high" instead of "range[0]" and "range[1]". (Suggested by Connor Abbot). - Use ir_builder swizzle helpers in swizzle_if_required(). (Suggested by Connor Abbot). - Make the logic more clearer by rearrenging the code and commenting. (Suggested by Connor Abbot). - Added comment to explain why we need to recurse twice. (Suggested by Connor Abbot). - If we cannot prune an expression, do not return early. Instead, attempt to prune its children. (Suggested by Connor Abbot). Other changes: - Instead of having a global "valid" visitor member, let the various functions that can determine this status return a boolean and check for its value to decide what to do in each case. This is more flexible and allows to recurse into children of parents that could not be prunned due to invalid ranges (so related to the last bullet in the review feedback). - Make sure we always check if a range is valid before working with it. Since any use of get_range, combine_range or range_intersection can invalidate a range we should check for this situation every time we use any of these functions. Version 3 by Iago Toral Quiroga <[email protected]>: Changes from review feedback: - Now we can make get_range, combine_range and range_intersection static too (suggested by Connor Abbot). - Do not return NULL when looking for the larger or greater constant into mixed vector constants. Instead, produce a new constant by doing a component-wise minmax. With this we can also remove of the validations when we call into these functions (suggested by Connor Abbot). - Add a comment explaining the meaning of the baserange argument in prune_expression (suggested by Connor Abbot). Other changes: - Eliminate minmax expressions operating on constant vectors with mixed values by resolving them. No piglit regressions observed with Version 3.
