Author: kadircet Date: Fri Mar 8 00:38:25 2019 New Revision: 355669 URL: http://llvm.org/viewvc/llvm-project?rev=355669&view=rev Log: [clangd] Adjust compile commands to be applicable for tooling
Summary: As can be seen in https://github.com/llvm-mirror/clang/blob/master/lib/Tooling/Tooling.cpp#L385 clang tool invocations adjust commands normally like this. In clangd we have different code paths for invoking a frontend action(preamble builds, ast builds, background index, clangd-indexer) they all work on the same GlobalCompilationDatabase abstraction, but later on are subject to different modifications. This patch makes sure all of the clangd actions make use of the same compile commands before invocation. Enables background-index to work on chromium codebase(since they had dependency file output in their compile commands).
