This patch allocates the NamespaceInfo types in the local arenas, and adapts the merging logic for the new list type and its children. Memory use and performance improve slightly. Micro-benchmarks show a regression in merge operations due to the more complex list operations. ## Build Clang-Doc Documentation | Metric | Baseline | Prev | This | Culm% | Seq% | | :--- | :--- | :--- | :--- | :--- | :--- | | Time | 920.5s | 1009.2s | 1002.4s | +8.9% | -0.7% | | Memory | 86.0G | 43.2G | 43.9G | -49.0% | +1.6% | ## Microbenchmarks (Filtered for >1% Delta) | Benchmark | Baseline | Prev | This | Culm% | Seq% | | :--- | :--- | :--- | :--- | :--- | :--- | | BM_BitcodeReader_Scale/10 | 67.9us | 69.7us | 69.3us | +1.9% | -0.7% | | BM_BitcodeReader_Scale/10000 | 70.5ms | 22.3ms | 24.8ms | -64.8% | +11.4% | | BM_BitcodeReader_Scale/4096 | 23.2ms | 4.7ms | 4.4ms | -80.9% | -5.7% | | BM_BitcodeReader_Scale/512 | 509.4us | 558.7us | 540.2us | +6.0% | -3.3% | | BM_BitcodeReader_Scale/64 | 114.8us | 119.2us | 117.0us | +1.9% | -1.8% | | BM_EmitInfoFunction | 1.6us | 1.6us | 1.6us | -1.1% | +0.8% | | BM_Index_Insertion/10 | 2.3us | 4.2us | 3.7us | +61.7% | -11.3% | | BM_Index_Insertion/10000 | 3.1ms | 5.4ms | 4.9ms | +56.8% | -9.1% | | BM_Index_Insertion/4096 | 1.3ms | 2.2ms | 2.0ms | +54.5% | -8.2% | | BM_Index_Insertion/512 | 153.6us | 259.6us | 236.7us | +54.1% | -8.8% | | BM_Index_Insertion/64 | 18.1us | 30.7us | 27.9us | +54.5% | -9.0% | | BM_JSONGenerator_Scale/10 | 36.8us | 37.6us | 36.6us | -0.7% | -2.7% | | BM_JSONGenerator_Scale/4096 | 33.7ms | 34.3ms | 34.2ms | +1.4% | -0.3% | | BM_JSONGenerator_Scale/64 | 222.4us | 225.6us | 220.2us | -1.0% | -2.4% | | BM_Mapper_Scale/10 | 2.5ms | 2.5ms | 2.5ms | -1.4% | -1.7% | | BM_Mapper_Scale/10000 | 104.3ms | 109.3ms | 105.9ms | +1.6% | -3.1% | | BM_Mapper_Scale/4096 | 44.3ms | 43.9ms | 44.7ms | +0.8% | +1.8% | | BM_Mapper_Scale/512 | 7.6ms | 7.6ms | 7.6ms | +0.8% | +1.2% | | BM_MergeInfos_Scale/10000 | 12.2ms | 1.6ms | 2.0ms | -83.6% | +28.7% | | BM_MergeInfos_Scale/2 | 1.9us | 1.7us | 1.7us | -8.1% | +0.9% | | BM_MergeInfos_Scale/4096 | 2.8ms | 520.5us | 557.4us | -79.9% | +7.1% | | BM_MergeInfos_Scale/512 | 68.9us | 37.9us | 39.9us | -42.0% | +5.3% | | BM_MergeInfos_Scale/64 | 10.3us | 6.3us | 6.5us | -36.7% | +2.7% | | BM_MergeInfos_Scale/8 | 2.8us | 2.2us | 2.2us | -20.7% | +1.2% | | BM_SerializeFunctionInfo | 25.5us | 25.8us | 26.1us | +2.1% | +1.1% |
//===----------------------------------------------------------------------===// // Clang Tools repository //===----------------------------------------------------------------------===// Welcome to the repository of extra Clang Tools. This repository holds tools that are developed as part of the LLVM compiler infrastructure project and the Clang frontend. These tools are kept in a separate "extra" repository to allow lighter weight checkouts of the core Clang codebase. All discussion regarding Clang, Clang-based tools, and code in this repository should be held using the standard Clang forums: https://discourse.llvm.org/c/clang https://discourse.llvm.org/c/clang/clang-tidy/71 https://discourse.llvm.org/c/clang/clangd/34 Code review for this tree should take place on Github: https://github.com/llvm/llvm-project/pulls?q=label%3Aclang-tools-extra If you find a bug in these tools, please file it in the LLVM bug tracker: https://github.com/llvm/llvm-project/issues/
