automatically. Use -S with llvm-gcc rather than -c, so tests can work when llvm-gcc is really dragonegg (which can output IR with -S but not -c). llvm-svn: 120160

// The "basic_string" extern template instantiation declaration is supposed to
|
|
// suppress the implicit instantiation of non-inline member functions. Make sure
|
|
// that we suppress the implicit instantiation of non-inline member functions
|
|
// defined out-of-line. That we aren't instantiating the basic_string
|
|
// constructor when we shouldn't be. Such an instantiation forces the implicit
|
|
// instantiation of _S_construct<const char*>. Since _S_construct is a member
|
|
// template, it's instantiation is *not* suppressed (despite being in
|
|
// basic_string<char>), so we would emit it as a weak definition.
