Fix the rest of PR2279: a) correct rejection of ',' in pp expressions. b) the precedence of ',' was wrong w.r.t. ?:. Thanks again to Neil for finding these and providing testcases. llvm-svn: 50625 2008-05-05 02:36:18 +08:00			`// Comma is not allowed in C89`
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 2009-12-16 04:14:24 +08:00			`// RUN: not %clang_cc1 -E %s -std=c89 -pedantic-errors`
