* Handle a code-completion token being passed to the macro stringify operator.Argyrios Kyrtzidis2011-09-041-0/+2
| | | | | | Fixes http://llvm.org/PR10826. llvm-svn: 139087
* Support code-completion for C++ inline methods and ObjC buffering methods.Argyrios Kyrtzidis2011-09-0415-179/+250
| | | | | | | | | | | | | | Previously we would cut off the source file buffer at the code-completion point; this impeded code-completion inside C++ inline methods and, recently, with buffering ObjC methods. Have the code-completion inserted into the source buffer so that it can be buffered along with a method body. When we actually hit the code-completion point the cut-off lexing or parsing. Fixes rdar://10056932&8319466 llvm-svn: 139086
* Fix Lexer::ComputePreamble when MaxLines parameter is non-zero.Argyrios Kyrtzidis2011-09-042-4/+20
| | | | | | | | The function was only counting lines that included tokens and not empty lines, but MaxLines (mainly initiated to the line where the code-completion point resides) is a count of overall lines (even empty ones). llvm-svn: 139085

* Teach -Wdangling-field to warn about temporaries bound to references asChandler Carruth2011-09-031-9/+17
| | | | | | | | | | | | | well. Also, clean up the flow of the code a bit, and factor things more nicely. Finally, add the test case that was missing from my previous commit (sorry), with new tests added to cover temporaries and other fun cases. llvm-svn: 139077
* Add a simple new warning to catch blatantly dangling pointer andChandler Carruth2011-09-031-2/+51
| | | | | | | | | | | | | | | | | reference members of classes. We've had several bugs reported because of this, and there's no reason not to flag it right away in the compiler. Comments especially welcome on the strategy for implementing this warning (IE, what should trigger this?) and on the text of the warning itself. I'm going to extend this to cover obvious cases with temporaries and beef up the test cases some in subsequent patches. I'll then run it over a large codebase and make sure its not misbehaving before I add it to -Wall or turn it on by default. I think this one might be a good candidate for on by default. llvm-svn: 139075

* Make StmtDumper::VisitCXXFunctionalCastExpr dump the attached cast kind. ↵Eli Friedman2011-09-022-4/+6
| | | | | | Fix the cast kind for a cast from floating-point to enum type. (The difference isn't actually visible, but that's just because IRGen is overly forgiving.) Per report by Enea Zaffanella on cfe-dev. llvm-svn: 139011

| | | | | | | | | Preprocessor, eliminating the constructor that was used by ASTUnit (which didn't provide an ASTContext or Prepreprocessor). Ensuring that both objects are non-NULL will simplify module loading (but none of that is done yet). llvm-svn: 138986

| | | | | | | | builtin types (When requested). This is another step toward making ASTUnit build the ASTContext as needed when loading an AST file, rather than doing so after the fact. No actual functionality change (yet). llvm-svn: 138985
* Allow the preprocessor to be constructed without performing target-Douglas Gregor2011-09-014-80/+115

* Modules hide macro definitions by default, so that silly things likeDouglas Gregor2011-09-019-43/+104
| | | | | | | | | | | include guards don't show up as macro definitions in every translation unit that imports a module. Macro definitions can, however, be exported with the intentionally-ugly #__export_macro__ directive. Implement this feature by not even bothering to serialize non-exported macros to a module, because clients of that module need not (should not) know that these macros even exist. llvm-svn: 138943
* Enable -fdelayed-template-parsing by default on Win32.Francois Pichet2011-09-011-2/+3
| | | | | | I had to force -fno-delayed-template-parsing on some Index tests because delayed template parsing will change the output of some tests. llvm-svn: 138942

* When defining the implicit move assignment operator, don't performDouglas Gregor2011-09-011-3/+9
| | | | | | | | semantic analysis when taking the address of an xvalue. Instead, just build the unary operator directly, since it's safe to do so (from the IRgen and AST perspectives) for any glvalue. Fixes PR10822. llvm-svn: 138935
* Support importing of ObjC categories from modules.Argyrios Kyrtzidis2011-09-014-1/+192
| | | | | | | | | | | | The initial incentive was to fix a crash when PCH chaining categories to an interface, but the fix was done in the "modules way" that I hear is popular with the kids these days. Each module stores the local chain of categories and we combine them when the interface is loaded. We also warn if non-dependent modules introduce duplicate named categories. llvm-svn: 138926
* Create a CaretDiagnostic class to hold the logic for emittingChandler Carruth2011-08-311-263/+331
| | | | | | | | | | | | | | (unsurprisingly) caret diagnostics. This is designed to bring some organization to the monstrous EmitCaretDiagnostic function, and allow factoring it more easily and with less mindless parameter passing. Currently this just lifts the existing function into a method, and splits off the obviously invariant arguments to be class members. No functionality is changed, and there are still lots of warts to let existing code continue functioning as-is. Definitely WIP, more cleanups to follow. llvm-svn: 138921
