New Revision: 197314
URL: http://llvm.org/viewvc/llvm-project?rev=197314&view=rev
Log:
Fix GCC unknown pragma warning in libc++.
We should check defined(__clang__) before the usage of the
clang diagnostic pragmas.
The [-Wswitch] warning in src/future.cpp should be ignored.
As the result, the equivalent GCC pragma is added.
