* spirv/nir: add support for ImageGatherExtendedIlia Mirkin2016-12-161-7/+69
| | | | | | | | | | The strategy is to do the same thing that the GLSL lower_offset_arrays pass does - create 4 separate texture gather ops, one per offset, and read in the results from each gather's w component to recreate the desired result.

* spirv: Use a simpler and more correct implementaiton of tanh()Jason Ekstrand2016-12-091-9/+14
| | | | | | | | | | The new implementation is more correct because it clamps the incoming value to 10 to avoid floating-point overflow. It also uses a much reduced version of the formula which only requires 1 exp() rather than 2. This fixes all of the dEQP-VK.glsl.builtin.precision.tanh.* tests.

* nir: Get rid of nir_constant_dataJason Ekstrand2016-12-022-42/+33
| | | | | | | | This has bothered me for about as long as NIR has been around. Why do we have two different unions for constants? No good reason other than one of them is a direct port from GLSL IR. Reviewed-by: Iago Toral Quiroga <[email protected]>
* nir/spirv: implement ordered / unordered floating point comparisons properlyIago Toral Quiroga2016-11-231-1/+52
| | | | | | | | | | | | | | | | | | | | | Besides the logical operation involved, these also require that we test if the operands are ordered / unordered. For ordered operations, both operands must be ordered (and they must pass the conditional test) while for unordered operations it is sufficient if only one of the operands is unordered (or they pass the logical test). Fixes the following Vulkan CTS tests: dEQP-VK.spirv_assembly.instruction.compute.opfunord.equal dEQP-VK.spirv_assembly.instruction.compute.opfunord.greater dEQP-VK.spirv_assembly.instruction.compute.opfunord.greaterequal dEQP-VK.spirv_assembly.instruction.compute.opfunord.less dEQP-VK.spirv_assembly.instruction.compute.opfunord.lessequal v2: Fixed typo: s/nir_eq/nir_feq Reviewed-by: Lionel Landwerlin <[email protected]>

Calls not switched to rzalloc_size: - ralloc_vasprintf - glsl_type::name allocation (it's filled with snprintf) - C++ classes where valgrind didn't show uninitialized values I switched most of non-glsl stuff to rzalloc without checking whether it's really needed.

* nir/spirv/cfg: Use a nop intrinsic for tagging the ends of blocksJason Ekstrand2016-10-032-4/+6
| | | | | | | | | | | | | | | | | | | | | Previously, we were saving off the last nir_block in a vtn_block before moving on so that we could find the nir_block again when it came time to handle phi sources. Unfortunately, NIR's control flow modification code is inconsistent when it comes to how it splits blocks so the block pointer we saved off may point to a block somewhere else in the shader by the time we get around to handling phi sources. In order to get around this, we insert a nop instruction and use that as the logical end of our block. Since the control flow manipulation code respects instructions, the nop will keeps its place like any other instruction and we can easily find the end of our block when we need it. This fixes a bug triggered by a couple of vkQuake shaders.

* nir/spirv/cfg: Detect switch_break after loop_break/continueJason Ekstrand2016-10-011-2/+2
| | | | | | | | | | | While the current CFG code is valid in the case where a switch break also happens to be a loop continue, it's a bit suboptimal. Since hardware is capable of handling the continue as a direct jump, it's better to use a continue instruction when we can than to bother with all of the nasty switch break lowering.

* nir/spirv/cfg: Handle switches whose break block is a loop continueJason Ekstrand2016-10-011-0/+13
| | | | | | | | | | | | | | | | It is possible that the break block of a switch is actually the continue of the loop containing the switch. In this case, we need to identify the break block as a continue and break out of current level of CFG handling. If we don't, the continue portion of the loop will get handled twice, once by following after the break and a second time by the loop handling code handling it explicitly. This fixes 6 of the new Vulkan CTS tests: - dEQP-VK.spirv_assembly.instruction.graphics.opphi.out_of_order* - dEQP-VK.spirv_assembly.instruction.graphics.selection_block_order.out_of_order* Signed-off-by: Jason Ekstrand <[email protected]> Cc: "12.0" <[email protected]>
