- Add divan benchmarks for compiler semantic analysis phase (internal/compiler/benches/semantic_analysis.rs) - Add custom allocator to track allocations in the benchmark. - Add benches for individual phases of compilation and a proc-macro simulation mode. - Document allocation hotspots and optimization strategies (docs/semantic-analysis-optimization.md) Benchmarks cover: - Lexing and parsing performance - Full compilation with various stress scenarios - Specific hotspots: many children, properties, exports, states, nested components, deep expressions, binding chains The optimization doc identifies key issues: - O(n²) export sorting - Element duplication in inlining pass - Incremental Vec growth patterns - SmallVec sizing recommendations
