From 5915af4533963ef3e759365465806767c74fb73b Mon Sep 17 00:00:00 2001 From: carlos-alm <127798846+carlos-alm@users.noreply.github.com> Date: Tue, 3 Mar 2026 22:43:11 -0700 Subject: [PATCH 1/3] =?UTF-8?q?perf:=20fix=20v3.0.1=20build=20performance?= =?UTF-8?q?=20regression=20(14.1=20=E2=86=92=20~5.8=20ms/file)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Three optimizations to recover build speed after CFG/dataflow default-on: 1. Eliminate redundant WASM parsing (biggest win): - Remove complexity.js clearing _tree after each file (builder already clears all trees after all phases complete) - Add ensureWasmTrees() in parser.js for a single WASM pre-parse pass before CFG/dataflow, replacing two independent parse passes - Memoize createParsers() so repeated calls return cached parsers 2. Filter CFG/dataflow to changed files only: - Build changedSymbols map excluding reverse-dep-only files - Pass changedSymbols (not allSymbols) to buildCFGData/buildDataflowEdges - Reverse-dep files only need edge rebuilding, not AST re-analysis 3.
