* spirv: Allow block-decorated struct types for constantsJason Ekstrand2020-07-121-1/+2
| | | | | | | | | | | Whenever a struct type is decorated Block or BufferBlock we turn that into a GLSL_TYPE_INTERFACE. Since these decorations can end up random places, we should allow them for constants. Closes: #3252 Fixes: 9d0ae777dd6 "spirv: Use interface type for block and buffer..."

* nir: Add an option for lowering TessLevelInner/Outer to vecsBrian Ho2020-06-222-0/+30
| | | | | | | | | | | | The GLSL to NIR compiler supports the LowerTessLevel flag to convert gl_TessLevelInner/Outer from their GLSL declarations as arrays of floats to vec4/vec2s to better match how they are represented in hardware. This commit adds the similar support to the SPIR-V to NIR compiler so turnip can use the same IR3/NIR tess lowering passes as freedreno.

* spirv: Rewrite CFG constructionJason Ekstrand2020-04-242-294/+503
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit completely rewrites the way we extract a structured CFG from SPIR-V. The new approach is different in a few ways: 1. It does a breadth-first search instead of depth-first. This means that we've visited the merge node for a construct before we visit any of the nodes inside the construct. This makes it easier to validate things like loop and switch nesting. 2. We record more information in the CFG. Earlier commits added a parent pointer to vtn_cf_node but we now record all of the merge and other special blocks for each CFG node. This lets us validate things more precisely. 3. It makes heavy use of merge blocks for walking the CFG. Previously, we sort of used them as hints for trying to guess the CFG structure but things got dicey whenever a merge was missing. We had some heuristics for how to handle short-circuiting if statements but it was a bunch of special cases. Now, we make them a fundamental part of walking the CFG. When we encounter a control-flow construct, we add the body components of the construct to the BFS work list and then jump to the merge block if one exists to continue scanning the current CFG nesting level. If no merge block exists, we assume that means that control-flow never re-converges in a normal way and that the only way to get back to normality is with a direct jump such as a loop break or continue. This should make things far more robust when trying to deal with the more creative placement (or lack thereof) of merge instructions.
