Author: ericwf Date: Fri Oct 2 21:32:23 2015 New Revision: 249226 URL: http://llvm.org/viewvc/llvm-project?rev=249226&view=rev Log: [libcxx] Use newest supported language dialect when running the test suite.
Summary: Currently the test suite defaults to C++11 mode if no standard version is supplied to LIT using `--param=std=c++XX`. This patch changes that behavior so that the newest possible dialect is selected instead. I have already patched the C++11 bot to explicitly specify `--param=std=c++11`. I'm just putting this up for review to see if anybody objects to this idea.
