Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'. - This is designed to make it obvious that %clang_cc1 is a "test variable" which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it can be useful to redefine what gets run as 'clang -cc1' (for example, to set a default target). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91446 91177308-0d34-0410-b5e6-96231b3b80d8

Add support for global initializers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@78515 91177308-0d34-0410-b5e6-96231b3b80d8

If a global initializer has a non-trivial constructor or destructor, we never want to defer generation of it, even if it is declared static. With this change we're finally able to compile and run the (infamous) #include <string> #include <iostream> int main(int argc, char **argv) { std::cout << "Hello, World" << std::endl; } $ clang hello.cpp -lstdc++ -o hello $ ./hello Hello, World git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83559 91177308-0d34-0410-b5e6-96231b3b80d8
