* Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.Daniel Dunbar2009-12-151-1/+1
| | | | | | | | | - 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

* Adopt a more principled approach to invalid declarations:Douglas Gregor2009-02-161-3/+1
| | | | | | | | | | | | | | | | | | | | | | | - If a declaration is an invalid redeclaration of an existing name, complain about the invalid redeclaration then avoid adding it to the AST (we can still parse the definition or initializer, if any). - If the declaration is invalid but there is no prior declaration with that name, introduce the invalid declaration into the AST (for later error recovery). - If the declaration is an invalid redeclaration of a builtin that starts with __builtin_, we produce an error and drop the redeclaration. If it is an invalid redeclaration of a library builtin (e.g., malloc, printf), warn (don't error!) and drop the redeclaration. If a user attempts to define a builtin, produce an error and (if it's a library builtin like malloc) suggest -ffreestanding. This addresses <rdar://problem/6097585> and PR2892. However, PR3588 is still going to cause some problems when builtins are redeclared without a prototype. llvm-svn: 64639
