Justin Bogner	502155aff9	Fix whitespace handling in ## operator ... In x ## y, where x and y are regular tokens, whitespace between x and ## is ignored, and whitespace between ## and y is also ignored. When either x or y is a function argument, whitespace was preserved, but it should not be. This patch removes the checks for whitespace before ## and before y, and in the special case where x is an empty macro argument and y is a regular token, actively removes whitespace before y. One existing test is affected by that change, but as clang's output now matches the standard's requirements and that of GCC, I've tweaked the testcase.

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	8b57697954	Eliminate &&s in tests. ... - 'for i in $(find . -type f); do sed -e 's#\(RUN:.*[^ ]\) *&& *$#\1#g' $i | FileUpdate $i; done', for the curious. llvm-svn: 86430	2009-11-08 01:45:36 +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
Argyrios Kyrtzidis	351763e156	Multiple tests in a single test file must be linked with '&&'. ... Otherwise, failing tests other than the last one will not be reported. llvm-svn: 52231	2008-06-12 12:40:02 +00:00
Chris Lattner	0c8a1edb8b	Fix a bug where we would incorrectly emit a "cannot paste" error ... message when handling the GNU ", ## __VA_ARGS__" extension. While I'm at it, flag uses of this as extensions. llvm-svn: 46503	2008-01-29 07:54:23 +00:00
