From d5217515002d468a3095243975e21e89eccc46b7 Mon Sep 17 00:00:00 2001 From: hlopko Date: Thu, 27 Apr 2017 10:47:15 +0200 Subject: Init absent action configs for CppCompile actions So far only link actions were initialized in CppLinkActionConfigs. This cl changes this class to also initialize CppCompile actions. This is needed for our ongoing work removing hard-coded flags from Bazel and moving them into Crosstool. RELNOTES: None.
