From 73bc73b5d2485f13f14c4c2475c436d90505ca65 Mon Sep 17 00:00:00 2001 From: ykiko Date: Wed, 25 Mar 2026 23:16:36 +0800 Subject: [PATCH 1/2] feat: add SearchConfig, ToolchainProvider, PathPool and related tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Introduce the search-config extraction pipeline that models clang's four-segment include directory layout (Quoted → Angled → System → After), a ToolchainProvider cache for `clang++ -###` queries, and a PathPool intern table for lightweight file-path identity. Also adds a shared TempDir test helper and ExtractSearchConfig unit tests.
