From 3c46bb9931ecea71167342322e09121ee48cde8e Mon Sep 17 00:00:00 2001 From: Ben Noordhuis Date: Fri, 5 Aug 2016 13:23:22 +0200 Subject: [PATCH] tools: add compile_commands.json gyp generator Add a compile_commands.json generator for use with clang-based tooling. Pass the (undocumented) -C switch to configure to make it generate the files in out/Debug and out/Release.
