From 7e03c676e4d1b9bde9d8a50ba6521f07df218704 Mon Sep 17 00:00:00 2001 From: Kousik Kumar Date: Tue, 22 Oct 2019 05:05:18 +0000 Subject: Refactor DependencyScanningTool to its own file Summary: There's no behavior change - just moving DependencyScanningTool to its own file since this tool can be reused across both clang-scan-deps binary and an interface exposed as part of libClang APIs.
