2012-08-24Allow RecursiveASTVisitor to visit CXXCtorInitializer objects for whichJames Dennett
isWritten() returns false, if shouldVisitImplicitCode() returns true. Previously those CXXCtorInitializers were always skipped. In order to make this change easier to test, this patch also extends the test class template ExpectedLocationVisitor to support arbitrary numbers of expected matches and disallowed matches. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162544 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-20DeclPrinter: add terse output mode and lots of testsDmitri Gribenko
Add a flag PrintingPolicy::DontRecurseInDeclContext to provide "terse" output from DeclPrinter. The motivation is to use DeclPrinter to print declarations in user-friendly format, without overwhelming user with inner detail of the declaration being printed. Also add many tests for DeclPrinter. There are quite a few things that we print incorrectly: search for WRONG in DeclPrinterTest.cpp -- and these tests check our output against incorrect output, so that we can fix/refactor/rewrite the DeclPrinter later. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162245 91177308-0d34-0410-b5e6-96231b3b80d8

and remove ASTContext reference (which was frequently bound to a dereferenced null pointer) from the recursive lump of printPretty functions.

This is the other half of C++11 [class.cdtor]p4 (the destructor side was added in r161915).

2012-08-14Attaching comments to redeclarations: fix wrong assumptionsDmitri Gribenko
The reason for the recent fallout for "attaching comments to any redeclaration" change are two false assumptions: (1) a RawComment is attached to a single decl (not true for 'typedef struct X *Y' where we want the comment to be attached to both X and Y); (2) the whole redeclaration chain has only a single comment (obviously false, the user can put a separate comment for each redeclaration). To fix (1) I revert the part of the recent change where a 'Decl*' member was introduced to RawComment. Now ASTContext has a separate DenseMap for mapping 'Decl*' to 'FullComment*'. To fix (2) I just removed the test with this assumption. We might not parse every comment in redecl chain if we already parsed at least one. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@161878 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-08Implement warning for integral null pointer constants other than the literal 0.David Blaikie
This is effectively a warning for code that violates core issue 903 & thus will become standard error in the future, hopefully. It catches strange null pointers such as: '\0', 1 - 1, const int null = 0; etc... There's currently a flaw in this warning (& the warning for 'false' as a null pointer literal as well) where it doesn't trigger on comparisons (ptr == '\0' for example). Fix to come in a future patch. Also, due to this only being a warning, not an error, it triggers quite frequently on gtest code which tests expressions for null-pointer-ness in a SFINAE context (so it wouldn't be a problem if this was an error as in an actual implementation of core issue 903). To workaround this for now, the diagnostic does not fire in unevaluated contexts. Review by Sean Silva and Richard Smith. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@161501 91177308-0d34-0410-b5e6-96231b3b80d8
