Shahbaz Youssefi 776c6015 2021-02-26T00:00:57 Vulkan: Call glslang at compile time With this change, the ANGLE translator immediately compiles the generated GLSL into SPIR-V with glslang and discards the source. This is in preparation for generating SPIR-V directly, by making the frontend and backend already able to digest it. This change also allows the expensive glslang calls to be parallelized, improving the following perf test by about 20%: LinkProgramBenchmark.Run/vulkan_compile_and_link_multi_thread Previously, the test was run as such in the Vulkan backend: Main Thread 1 Thread 2 Compile1 ---> Compile2 ---------------------> Translator Translator <--- <--------------------- Link glslang for shader1 glslang for shader2 Done With this change, it is run as such: Main Thread 1 Thread 2 Compile1 ---> Compile2 ---------------------> Translator Translator glslang glslang <--- <--------------------- Link Done glslang_wrapper_utils no longer interacts with glslang!

Shahbaz Youssefi 77637f2d 2021-02-19T15:18:52 Vulkan: Generate xfb support code in SPIR-V for emulation path This change moves the code generation at link time from source code to SPIR-V. As a result, transform feedback extension and emulation paths are more similarly handled before SPIR-V transformation (they both store information identically in the ShaderInterfaceVariableInfoMap). This change gets rid of the @@ XFB-OUT @@ marker. With no source code generation at link time, shader compilation can be moved to glCompileShader time.

Jamie Madill 093250e0 2020-12-23T12:07:46 Vulkan: Make shader variable info maps a class. Instead of using a map type directly we abstract the info maps into an encapsulated class. We can enforce a specific API set instead of using the same API as the map class. This also cleans up a few of the APIs related to these maps. This change will allow future changes to the way the variables are stored in the class without drastically changing the interface.

Le Hoang Quyen 6136cbcb 2020-09-23T21:31:05 Metal: Implement transform feedback - XFB is currently emulated by writing to storage buffers. - Metal doesn't allow vertex shader to both write to storage buffers and to stage output (i.e clip position). So if GL_RASTERIZER_DISCARD is NOT enabled, the draw with XFB enabled will have 2 passes: + First pass: vertex shader writes to XFB buffers + not write to stage output + disable rasterizer. + Second pass: vertex shader writes to stage output (i.e. [[position]]) + enable rasterizer. If GL_RASTERIZER_DISCARD is enabled, the second pass is omitted. + This effectively executes the same vertex shader twice. TODO: possible improvement is writing vertex outputs to buffer in first pass then re-use that buffer as input for second pass which has a passthrough vertex shader. - If GL_RASTERIZER_DISCARD is enabled, and XFB is enabled: + Only first pass above will be executed, and the render pass will use an empty 1x1 texture attachment since rasterization is not needed. - If GL_RASTERIZER_DISCARD is enabled, but XFB is NOT enabled: + we still enable Metal rasterizer. + but vertex shader must emulate the discard by writing gl_Position = (-3, -3, -3, 1). This effectively moves the vertex out of clip space's visible area. + This is because GLSL still allows vertex shader to write to stage output when rasterizer is disabled. However, Metal doesn't allow that. In Metal, if rasterizer is disabled, then vertex shader must not write to stage output. - See src/libANGLE/renderer/metal/doc/TransformFeedback.md for more details.

Le Hoang Quyen 1677cf14 2020-09-13T20:14:59 Metal: Implement Uniform buffers Uniform buffer is implemented in two forms: - If number of ubo used in shader program is low, each buffer will use one discrete Metal buffer slot. - If number of ubo used is large, they will be embedded into one Metal argument buffer. Argument buffer is similar to Vulkan descriptor set. This is due to limit of number of Metal's discrete buffer slots which is only 31 and over half of them are already used by vertex attributes, default uniforms, driver uniforms, etc. The downside is that whenever a buffer binding is changed, the argument buffer must be updated also. Added empty TransformFeedbackMtl implementation to enable ES3 context creation on Metal.

Le Hoang Quyen 5e13757b 2020-05-11T00:50:00 Metal: Fix array of structs containing array of samplers bug. Previously ProgramMtl could try to bind fixed slots to samplers based on layout (set=..., binding=...). However, GLSL layout model is different from Metal slots assignment. For example, The following is valid layout in GLSL: - array samplers A[2] is bound to index 0. - array samplers B[2] is bound to index 1. It is invalid to do so in Metal, since A occupies 2 slots, thus samplers B[2] must be bound to slots starting from 2. New binding method: let spirv-cross auto assigns the texture slots and retrieve them after compilation. Incomplete textures moved to ContextMtl using IncompleteTextureSet. New test added: GLSLTest.ArrayOfStructContainingArrayOfSamplers.

Shahbaz Youssefi e5385ea9 2020-01-27T13:40:18 Vulkan: Compile shaders at link time Since line raster emulation was changed to use specialization constants, it has been possible to compile shaders at link time. However, program pipeline objects would have required keeping the shader sources around for recompilation. Now that all necessary decorations are modified directly in SPIR-V, it's possible to compile the shaders at link time and forget about their sources. Program pipeline objects then simply "reconfigure" the generated SPIR-V. A next step could be to also create the Vulkan pipeline object at link time. A number of failures due to gaps in CTS testing prevent that work currently. In particular, in some situations the generated SPIR-V is not per spec, for example it may contain vertex attributes with aliasing locations, or have transform feedback capture of array elements misconfigured.

Currently, descriptor set and binding indices are set by the transformer. The shader translator outputs arbitrary set and binding indices. Once compiled by glslang, the SPIR-V transformer modifies these decorations. The ultimate goal is to be able to modify the SPIR-V again when program pipeline objects decide a different set/binding is necessary.
