* Use IR pass to eliminate phi nodes (#2226)Theresa Foley2022-05-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Use IR pass to eliminate phi nodes "Phi nodes" are one of the key contrivances that makes SSA (Static Single Assignment) form work. Because SSA is so great for compiler IRs, we kind of need to deal with phi nodes, but they also get in the way because they don't have a direct analog in most lower-level machine ISAs or execution models, nor in most of the high-level languages a transpiler wants to emit. As a result a compiler like ours needs to be able to eliminate the phi nodes from a program as part of generating output code. (For any clever people noting that SPIR-V supports phi nodes directly: yes, it does. It doesn't need to and it probably *shouldn't*. Anybody involved in the decision-making knows my reasoning, and anybody else should feel free to ask me if they want the lecture. Anyway...) The basic idea of elimiating phi nodes is simple enough. We replace each phi node with a temporary variable. Uses of the phi use values loaded from the temporary. The operation of the phi itself (assigning a value based on the branch taken) amounts to an assignment into the temporary. Previously, the Slang compiler dealt with phi nodes very late in the process of generating code: in the middle of emitting strings of source code in a high-level language like HLSL or GLSL. Doing the work that late in compilation has two big drawbacks: 1. Our ability to emit clean and/or optimal code is limited because we may not be able to make certain changes to the IR, or because we cannot make use of additional information like a dominator tree that might be available at other points in compilation. 2. Any other IR passes that relate to temporary variables won't be able to see the variables that we generate for phi nodes. This could raise issues with correctness (e.g., if we want to compute live-range information for *all* temporary variables), or performance (we have no way to run additional IR optimization passes after phis are eliminated). This change addresses these problems by making the elimination of phi nodes an explicit IR pass. Additional optimizations can easily be run after this pass (although we'd need to be careful not to run passes that could end up introducing new phis). The pass makes use of the information available to it to try to produce code that will emit to "clean" HLSL/GLSL. The core of the pass is in `slang-ir-eliminate-phis.cpp`, and is heavily commented, so I won't describe the approach in detail here. There are two related issues that came up, though: First, it turned out that our emit logic for local variables (`IRVar` instructions) wasn't using the function we'd defined named `emitVar()`. One worrying consequence of that oversight was that the `precise` modifier would impact generated HLSL/GLSL for variables that turned into SSA values (including phi nodes), but *not* for local variables that had not been SSA'd (or that had been SSA'd and then de-SSA'd). This change also fixes that bug; it is unclear how widespread the impact of the original issue might be. Second, generating explicit IR temporaries for phi nodes exposed a pre-existing bug in the `slang-ir-restructure-scoping` pass. That pass basically detects cases where we have an instruction `I` with a use `U` such that the use follows the rules of SSA form ("def dominates use," meaning `I` dominations `U`), but does not follow the more restrictive scoping rules of high-level-language output (where a value computed "inside" a loop is not automatically visible to code outside the loop just because it dominates that code). That pass did not correctly account for the case where `I` was a temporary variable. It seems that case could not arise before now because we didn't have any passes that would move `var`, `load`, or `store` operations out of the basic block they started in. The fix for that pass was relatively simple, and will make the whole thing more robust in case we add more aggressive optimizations later. * fixup: expected test output
