John McCall	8377967543	Warn about code that uses variables and functions with internal linkage ... without defining them. This should be an error, but I'm paranoid about "uses" that end up not actually requiring a definition. I'll revisit later. Also, teach IR generation to not set internal linkage on variable declarations, just for safety's sake. Doing so produces an invalid module if the variable is not ultimately defined. Also, fix several places in the test suite where we were using internal functions without definitions. llvm-svn: 126016	2011-02-19 02:53:41 +00:00
Daniel Dunbar	8fbe78f6fc	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	2009-12-15 20:14:24 +00:00
Daniel Dunbar	a45cf5b6b0	Rename clang to clang-cc. ... Tests and drivers updated, still need to shuffle dirs. llvm-svn: 67602	2009-03-24 02:24:46 +00:00
