Add passes to eliminate dead output stores (#4970) This adds two passes to accomplish this: one pass to analyze a shader to determine the input slots that are live. The second pass is run on the preceding shader to eliminate any stores to output slots that are not consumed by the following shader. These passes support vert, tesc, tese, geom, and frag shaders. These passes are currently only available through the API. These passes together with dead code elimination, and elimination of dead input and output components and variables (WIP), will allow users to do dead code elimination across shader boundaries.

Add spirv-opt convert-to-sampled-image pass (#4340) convert-to-sampled-image pass converts images and/or samplers with given pairs of descriptor set and binding to sampled image. If a pair of an image and a sampler have the same pair of descriptor set and binding that is one of the given pairs, they will be converted to a sampled image. In addition, if only an image has the descriptor set and binding that is one of the given pairs, it will be converted to a sampled image as well. For example, when we have %a = OpLoad %type_2d_image %texture %b = OpLoad %type_sampler %sampler %combined = OpSampledImage %type_sampled_image %a %b %value = OpImageSampleExplicitLod %v4float %combined ... 1. If %texture and %sampler have the same descriptor set and binding %combine_texture_and_sampler = OpVaraible %ptr_type_sampled_image_Uniform ... %combined = OpLoad %type_sampled_image %combine_texture_and_sampler %value = OpImageSampleExplicitLod %v4float %combined ... 2. If %texture and %sampler have different pairs of descriptor set and binding %a = OpLoad %type_sampled_image %texture %extracted_image = OpImage %type_2d_image %a %b = OpLoad %type_sampler %sampler %combined = OpSampledImage %type_sampled_image %extracted_image %b %value = OpImageSampleExplicitLod %v4float %combined ...

Add a new legalization pass to dedupe invocation interlock instructions (#5409) Add a new legalization pass to dedupe invocation interlock instructions DXC will be adding support for HLSL's rasterizer ordered views by using the SPV_EXT_fragment_shader_interlock_extension. That extension stipulates that if an entry point has an interlock ordering execution mode, it must dynamically execute OpBeginInvocationInterlockEXT and OpEndInvocationInterlockEXT, in that order, exactly once. This would be difficult to determine in DXC's SPIR-V backend, so instead we will emit these instructions potentially multiple times, and use this legalization pass to ensure that the final SPIR-V follows the specification. This PR uses data-flow analysis to determine where to place begin and end instructions; in essence, determining whether a block contains or is preceded by a begin instruction is similar to a specialized case of a reaching definitions analysis, where we have only a single definition, such as `bool has_begun = false`. For this simpler case, we can compute the set of blocks using BFS to determine the reachability of the begin instruction. We need to do this for both begin and end instructions, so I have generalized portions of the code to run both forward and backward over the CFG for each respective case.

This pass can be used for VUID-StandaloneSpirv-VulkanMemoryModel-04678 and VUID-StandaloneSpirv-VulkanMemoryModel-04679 (See "Standalone SPIR-V Validation" section of Vulkan spec "Appendix A: Vulkan Environment for SPIR-V"). Handle variables used by multiple entry points: 1. Update error check to make it working regardless of the order of entry points. 2. For a variable, if it is used by two entry points E1 and E2 and it needs the Volatile semantics for E1 while it does not for E2 - If VulkanMemoryModel capability is enabled, which means we have to set memory operation of load instructions for the variable, we update load instructions in E1, but do not update the ones in E2. - If VulkanMemoryModel capability is disabled, which means we have to add Volatile decoration for the variable, we report an error because E1 needs to add Volatile decoration for the variable while E2 does not. For the simplicity of the implementation, we assume that all functions other than entry point functions are inlined.

opt: add capability trimming pass (not default). (#5278) This commit adds a new optimization which tries to remove unnecessary capabilities from a SPIR-V module. When compiling a SPIR-V module, you may have some dead-code using features gated by a capability. DCE will remove this code, but the capability will remain. This means your module would still require some capability, even if it doesn't require it. Calling this pass on your module would remove obsolete capabilities. This pass wouldn't be enabled by default, and would only be usable from the API (at least for now). NOTE: this commit only adds the basic skeleton/structure, and doesn't mark as supported many capabilities it could support. I'll add them as supported as I write tests.
