| | | | | | | | | | | | | | | | | | | | | | | | llvm::sys::getOS{Name,Version}. Right now the implementation just derives from LLVM_HOSTTRIPLE (which is wrong, but it doesn't look like we have a define for the target triple). Ideally this routine would actually be able to compute the triple for targets we care about. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68118 91177308-0d34-0410-b5e6-96231b3b80d8
