* nir/opt_loop_unroll: Remove unneeded phis if we make progressTimothy Arceri2018-08-291-1/+9
| | | | | | | | | | | Now that SSA values can be derefs and they have special rules, we have to be a bit more careful about our LCSSA phis. In particular, we need to clean up in case LCSSA ended up creating a phi node for a deref. This avoids validation issues with some CTS tests with the following patch, but its possible this we could also see the same problem with the existing unrolling passes.

* mesa: Add GL/GLSL plumbing for INTEL_fragment_shader_orderingKevin Rogovin2018-08-281-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | This extension provides new GLSL built-in function beginFragmentShaderOrderingIntel() that guarantees (taking wording of GL_INTEL_fragment_shader_ordering extension) that any memory transactions issued by shader invocations from previous primitives mapped to same xy window coordinates (and same sample when per-sample shading is active), complete and are visible to the shader invocation that called beginFragmentShaderOrderingINTEL(). One advantage of INTEL_fragment_shader_ordering over ARB_fragment_shader_interlock is that it provides a function that operates as a memory barrie (instead of a defining a critcial section) that can be called under arbitary control flow from any function (in contrast the begin/end of ARB_fragment_shader_interlock may only be called once, from main(), under no control flow.

* nir: Add an array copy optimizationJason Ekstrand2018-08-233-0/+414
| | | | | | | | | | | | This peephole optimization looks for a series of load/store_deref or copy_deref instructions that copy an array from one variable to another and turns it into a copy_deref that copies the entire array. The pattern it looks for is extremely specific but it's good enough to pick up on the input array copies in DXVK and should also be able to pick up the sequence generated by spirv_to_nir for a OpLoad of a large composite followed by OpStore. It can always be improved later if needed. Reviewed-by: Caio Marcelo de Oliveira Filho <[email protected]>
* nir: Add a array-of-vector variable shrinking passJason Ekstrand2018-08-232-0/+718

* nir: Add an array splitting passJason Ekstrand2018-08-232-0/+584
| | | | | | | | | | | | | | | | | | | | | | | This pass looks for array variables where at least one level of the array is never indirected and splits it into multiple smaller variables. This pass doesn't really do much now because nir_lower_vars_to_ssa can already see through arrays of arrays and can detect indirects on just one level or even see that arr[i][0][5] does not alias arr[i][1][j]. This pass exists to help other passes more easily see through arrays of arrays. If a back-end does implement arrays using scratch or indirects on registers, having more smaller arrays is likely to have better memory efficiency. v2 (Jason Ekstrand): - Better comments and naming (some from Caio) - Rework to use one hash map instead of two v2.1 (Jason Ekstrand): - Fix a couple of bugs that were added in the rework including one which basically prevented it from running Reviewed-by: Caio Marcelo de Oliveira Filho <[email protected]>

* nir: Skip common instructions when comparing deref pathsCaio Marcelo de Oliveira Filho2018-08-221-0/+3
| | | | | | | | | | | | | | | | | | | Deref paths may share the same deref instructions in their chains, e.g. ssa_100 = deref_var A ssa_101 = deref_struct "array_field" of ssa_100 ssa_102 = deref_array "[1]" of ssa_101 ssa_103 = deref_struct "field_a" of ssa_102 ssa_104 = deref_struct "field_a" of ssa_103 when comparing the two last deref instructions, their paths will share a common sequence ssa_100, ssa_101, ssa_102. This patch skips to next iteration if the deref instructions are the same. Path[0] (the var) is still handled specially, so in the case above, only ssa_101 and ssa_102 will be skipped.

* nir: allow more nested loops to be unrolledTimothy Arceri2018-08-181-14/+17
| | | | | | | | | | | | | | | | | | | | The innermost check was added to stop us from unrolling multiple loops in a single pass, and to stop outer loops from unrolling. When we successfully unroll a loop we need to run the analysis pass again before deciding if we want to go ahead an unroll a second loop. However the logic was flawed because it never tried to unroll any nested loops other than the first innermost loop it found. If this innermost loop is not unrolled we end up skipping all other nested loops. This unrolls a loop in a Deus Ex: MD shader on ultra settings and also unrolls a loop in a shader from the game Prey when running on DXVK. Reviewed-by: Jason Ekstrand <[email protected]>
