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). llvm-svn: 91446

Turn access control on by default in -cc1. Remove -faccess-control from -cc1; add -fno-access-control. Make the driver pass -fno-access-control by default. Update a bunch of tests to be correct under access control. llvm-svn: 100880

Emit weak vtables of non-template classes with hidden visibility. llvm-svn: 110107

Just disable the hidden-visibility optimization for now by hiding it behind a -cc1 option. The Darwin linker complains about mixed visibility when linking gcc-built objects with clang-built objects, and the optimization isn't really that valuable. Platforms with less ornery linkers can feel free to enable this. llvm-svn: 110979

It turns out that linkers (at least, the Darwin linker) don't necessarily do the right thing with mixed-visibility symbols, so disable the visibility optimization where that's possible, i.e. with template classes (since it's possible that an arbitrary template might be subject to an explicit instantiation elsewhere). 447.dealII actually does this. I've put the code under an option that's currently not hooked up to anything. llvm-svn: 110374
