2011-09-27When 'bool' is not a built-in type but is defined as a macro, printDouglas Gregor

2011-09-19Fix a QoI bug with overloaded operators inside macros.Matt Beaumont-Gay
We were failing to set source locations and ranges in isUnusedResultAWarning for CXXOperatorCallExprs, leading to an "expression result unused" warning with absolutely no context if the expression was inside a macro. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140036 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-13In general, don't look through explicit casts when tryingJohn McCall
to find the called declaration. Explicit casts can radically change the semantics of a call, and it's no longer really a builtin call any more than it would be a builtin call if you stored the function pointer into a variable and called that. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139659 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-13[PCH] Fix a regression that r139441 introduced (decls were getting passedArgyrios Kyrtzidis
to the consumer without being fully deserialized). The regression was on compiling boost.python and it was too difficult to get a reduced test case unfortunately. Also modify the logic of how objc methods are getting passed to the consumer; codegen depended on receiving objc methods before the implementation decl. Since the interesting objc methods are ones with a body and such methods only exist inside an ObjCImplDecl, deserialize and pass to consumer all the methods of ObCImplDecl when we see one. Fixes http://llvm.org/PR10922 & rdar://10117105. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139644 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-13Switch LangOptions over to a .def file that describes header of theDouglas Gregor
language options. Use that .def file to declare the LangOptions class and initialize all of its members, eliminating a source of annoying initialization bugs. AST serialization changes are next up. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139605 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-10When converting a block pointer to an Objective-C pointer type, extendJohn McCall
the lifetime of the block by copying it to the heap, or else we'll get a dangling reference because the code working with the non-block-typed object will not know it needs to copy. There is some danger here, e.g. with assigning a block literal to an unsafe variable, but, well, it's an unsafe variable. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139451 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-10Clean up our handling of Objective-C definitions in AST files. RatherDouglas Gregor
than having CodeGen check whether a declaration comes from an AST file (which it shouldn't know or care about), make sure that the AST writer and reader pass along "interesting" declarations that CodeGen needs to know about. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139441 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-10Extend the Stmt AST to make it easier to look through label, default,Chandler Carruth
and case statements. Use this to make the logic in the CFG builder more robust at finding the actual statements within a compound statement, even when there are many layers of labels obscuring it. Also extend the test cases for a large chunk of PR10063. Still more work to do here though. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139437 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-09Give conversions of block pointers to ObjC pointers a different cast kindJohn McCall
than conversions of C pointers to ObjC pointers. In order to ensure that we've caught every case, add asserts to CastExpr that strictly determine which cast kind is used for which kind of bit cast. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139352 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-08Allow C++0x enumerations with a fixed underlying type inDouglas Gregor
Objective-C. The @encode'ing of such an enumeration type is the same as its underlying type. <rdar://problem/5276348>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139297 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-08Implement the Objective-C 'instancetype' type, which is an alias ofDouglas Gregor
'id' that can be used (only!) via a contextual keyword as the result type of an Objective-C message send. 'instancetype' then gives the method a related result type, which we have already been inferring for a variety of methods (new, alloc, init, self, retain). Addresses <rdar://problem/9267640>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139275 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-06When extracting the callee declaration from a call expression, be sureDouglas Gregor
to look through SubstNonTypeTemplateParmExprs. Then, update the IR generation of CallExprs to actually use CallExpr::getCalleeDecl() rather than attempting to mimick its behavior (badly). Fixes <rdar://problem/10063539>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139185 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-05Implement the suggested resolution of WG21 N3307 issue 19: When determining ↵Richard Smith
whether a class is an aggregate in C++0x, treat all functions which are neither deleted nor defaulted as user-provided, not just special member functions. The wording of the standard only defines the term "user-provided" for special member functions, but the intent seems to be that any function can be user-provided. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139111 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-02Make StmtDumper::VisitCXXFunctionalCastExpr dump the attached cast kind. ↵Eli Friedman
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139011 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-02Extend the ASTContext constructor to delay the initialization ofDouglas Gregor
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). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138985 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-01Teach ASTContext and Preprocessor to hold on to references to the sameDouglas Gregor
LangOptions, rather than making distinct copies of LangOptions. Granted, LangOptions doesn't actually get modified, but this will eventually make it easier to construct ASTContext and Preprocessor before we know all of the LangOptions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138959 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-01Support importing of ObjC categories from modules.Argyrios Kyrtzidis
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138926 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-31Improve the diagnostic text for -Wmissing-noreturn to include the nameChandler Carruth
of the function in question when applicable (that is, not for blocks). Patch by Joerg Sonnenberger with some stylistic tweaks by me. When discussing this weth Joerg, streaming the decl directly into the diagnostic didn't work because we have a pointer-to-const, and the overload doesn't accept such. In order to make my style tweaks to the patch, I first changed the overload to accept a pointer-to-const, and then changed the diagnostic printing layer to also use a pointer-to-const, cleaning up a gross line of code along the way. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138854 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-30Declare and define implicit move constructor and assignment operator.Sebastian Redl
This makes the code duplication of implicit special member handling even worse, but the cleanup will have to come later. For now, this works.

2011-08-26When we're deserializing declarations lexically stored in a RecordDeclDouglas Gregor
after having already deserialized the fields, clear out the fields first. This makes sure that we keep all of the declarations in the lexical context (including those implicitly added by later type-checking) within the same list. A test case for this behavior is coming as part of another commit; testing for this problem in isolation is a nightmare. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138661 91177308-0d34-0410-b5e6-96231b3b80d8
