* compiler: Move double_inputs to gl_program::DualSlotInputsJason Ekstrand2018-09-061-3/+0
| | | | | | | | | | | | | | | | | | | | | | | Previously, we had two field in shader_info: double_inputs_read and double_inputs. Presumably, the one was for all double inputs that are read and the other is all that exist. However, because nir_gather_info regenerates these two values, there is a possibility, if a variable gets deleted, that the value of double_inputs could change over time. This is a problem because double_inputs is used to remap the input locations to a two-slot-per-dvec3/4 scheme for i965. If that mapping were to change between glsl_to_nir and back-end state setup, we would fall over when trying to map the NIR outputs back onto the GL location space. This commit changes the way slot re-mapping works. Instead of the double_inputs field in shader_info, it adds a DualSlotInputs bitfield to gl_program. By having it in gl_program, we more easily guarantee that NIR passes won't touch it after it's been set. It also makes more sense to put it in a GL data structure since it's really a mapping from GL slots to back-end and/or NIR slots and not really a NIR shader thing.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | v2: An attempt to support SpvExecutionModeStencilRefReplacingEXT's behavior also follows, with the interpretation to said mode being we prevent writes to the built-in FragStencilRefEXT variable when the execution mode isn't set. v3: A more cautious reading of 1db44252d01bf7539452ccc2b5210c74b8dcd573 led me to a missing change that would stop (what I later discovered were) GPU hangs on the CTS test written to exercise this. v4: Turn FragStencilRefEXT decoration usage without StencilRefReplacingEXT mode into a warning, instead of trying to make the variable read-only. If we are to follow the originating extension on GL, the built-in variable in question should never be readable anyway. v5/v6: rebases. v7: Fix check for gen9 lost in rebase. (Ilia) Reduce the scope of the bool used to track whether SpvExecutionModeStencilRefReplacingEXT was used. Was in shader_info, moved to vtn_builder. (Jason) v8: Assert for fragment shader handling StencilRefReplacingEXT execution mode. (Caio) Remove warning logic, since an entry point might not have StencilRefReplacingEXT execution mode, but the global output variable might still exist for another entry point in the module.

* mesa: Add GL/GLSL plumbing for ARB_fragment_shader_interlock.Plamena Manolova2018-06-011-0/+5
| | | | | | | | | | | | | This extension provides new GLSL built-in functions beginInvocationInterlockARB() and endInvocationInterlockARB() that delimit a critical section of fragment shader code. For pairs of shader invocations with "overlapping" coverage in a given pixel, the OpenGL implementation will guarantee that the critical section of the fragment shader will be executed for only one fragment at a time.

* spirv/radv: add AMD_gcn_shader capability, remove current extensionsAlejandro Piñeiro2018-03-151-5/+1
| | | | | | | | | | | | | | | | | | | | | | So now, during spirv_to_nir, it uses the capability instead of the extension. Note that we are really doing here is treating SPV_AMD_gcn_shader as other supported extensions. SPV_AMD_gcn_shader is not the first SPV extension supported. For example, the capability draw_parameters infers if the extension SPV_KHR_shader_draw_parameters is supported or not. This could be seen as counter-intuitive, and that it would be easier to define which extensions are supported, and based our checks on that, but we need to take into account that some capabilities are optional from core, and others came from new extensions. Also this commit would make the implementation of ARB_spirv_extensions easier. v2: AMD_gcn_shader capability renamed to gcn_shader (Daniel Schürmann) Reviewed-by: Daniel Schürmann <[email protected]> Reviewed-by: Bas Nieuwenhuizen <[email protected]>

* compiler: Merge shader_info's tcs and tes structs.Kenneth Graunke2017-01-101-4/+3
| | | | | | | | | | | | | | | Annoyingly, SPIR-V lets you specify all of these fields in either the TCS or TES, which means that we need to be able to store all of them for either shader stage. Putting them in a union won't work. Combining both is an easy solution, and given that the TCS struct only had a single field, it's pretty inexpensive. This patch renames the combined struct to "tess" to indicate that it's for tessellation in general, not one of the two stages.
