Author: yaxunl Date: Wed Aug 29 13:39:22 2018 New Revision: 340967 URL: http://llvm.org/viewvc/llvm-project?rev=340967&view=rev Log: Add predefined macro __gnu_linux__ for proper aux-triple
Clang predefine macro __linx__ for aux-triple with Linux OS but does not predefine macro __gnu_linux__. This causes some compilation error for certain applications, e.g. Eigen. This patch fixes that.
