* glsl: Remove bonus tree walking in opt_constant_folding().Kenneth Graunke2016-05-151-2/+0
| | | | | | | | | | | | | | It looks like this was missed when converting opt_constant_folding() from a hierarchical visitor to an rvalue visitor in 6606fde3. ir_rvalue_visitor already processes values on the way back up the tree, so we will have already visited every child node. There's no point in doing it again. No change in shader-db. Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Ian Romanick <[email protected]>
* glsl: Make opt_constant_variable() bail in useless cases.Kenneth Graunke2016-05-151-0/+7
| | | | | | | | | | | | | | | The pass ultimately skips over any entries with assignment_count != 1, so there's no need to do further work once we've determined that there are multiple assignments. The constant value could be a large array (i.e. uvec4[327]), at which point skipping the constant_expression_value() call (and the clone() call within) can save us piles of memory.

* nv50/ir: avoid asserts when the state tracker feeds us bogus inputsIlia Mirkin2016-05-151-12/+48
| | | | | | | | | | | | | | | | | | INTERP is defined (by me) to have to have a INPUT source. However the state tracker does not always obey this. This happens due to varying packing logic introducing additional mov's which can't always be undone. Instead of just giving up, we instead try harder to find the original input. This won't always be possible, for example with indirect accesses. There's not much we can (easily) do about that though. This fixes the remaining interpolateAt* failures in dEQP: dEQP-GLES31.functional.shaders.multisample_interpolation.interpolate_at* some of which were asserting due to INTERP_* being passed a non-input.

| | | | | | | | | | | | | | This fixes dEQP-GLES31.functional.draw_indirect.draw_elements_indirect.*.default_attribute These tests were causing a const vbo to be set up, and were small enough draws that the logic was trying to go via the push path (which emits data directly into the cmd stream rather than uploading a user vbo).

* nvc0/ir: make sure to align the second arg of TXD to 4, as we do for TEXIlia Mirkin2016-05-151-0/+14
| | | | | | | | | | | | | This was handled in handleTEX(), however the way the logic works, those extra arguments aren't added on by then, so it did nothing. Instead we must duplicate that bit here. GK110 appears to complain about MISALIGNED_GPR, however it's reasonable to believe that GK104 has the same requirements.

* nir: Add texture opcodes and source types for multisample compressionJason Ekstrand2016-05-142-0/+12
| | | | | | | | | | | Intel hardware does a form of multisample compression that involves an auxilary surface called the MCS. When an MCS is in use, you have to first sample from the MCS with a special opcode and then pass the result of that operation into the next sample instrucion. Normally, we just do this ourselves in the back-end, but we want to expose that functionality to NIR so that we can use MCS values directly in NIR-based blorp.
