Author: manojgupta Date: Sat Apr 7 12:59:58 2018 New Revision: 329512 URL: http://llvm.org/viewvc/llvm-project?rev=329512&view=rev Log: [Driver] Update GCC libraries detection logic for Gentoo.
Summary: 1. Find GCC's LDPATH from the actual GCC config file. 2. Avoid picking libraries from a similar named tuple if the exact tuple is installed.
