Author: fedor.sergeev Date: Tue Feb 6 05:21:12 2018 New Revision: 324344 URL: http://llvm.org/viewvc/llvm-project?rev=324344&view=rev Log: [Solaris] Silence -pthread warning on Solaris
Summary: During make check-all on Solaris, I see several instances of this warning: clang-6.0: warning: argument unused during compilation: '-pthread' [-Wunused-command-line-argument] Since Solaris 10, libpthread has been folded into libc, so there's nothing to do. gcc just ignores -pthread here. Darwin claims the option to silence the warning, and this patch follows that lead.
