2010-08-16A field of incomplete type is sufficiently disruptive that we should markJohn McCall
the record invalid. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111211 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-13Change Sema's UnusedStaticFuncs to UnusedFileScopedDecls to allow also ↵Argyrios Kyrtzidis
keeping track of unused file scoped variables. This is only preparation, currently only static function definitions are tracked, as before. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111025 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-11Speculatively revert r110610 " Make ObjCInterfaceDecl redeclarable,Douglas Gregor
and create separate decl nodes for forward declarations and the definition," which appears to be causing significant Objective-C breakage. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110803 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-10Fix redefinition of typedefs of fixable variably-modified array types; shouldEli Friedman
fix an issue compiling <windows.h>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110651 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-09- Make ObjCInterfaceDecl redeclarable, and create separate decl nodes for ↵Sebastian Redl
forward declarations and the definition. - Eagerly create ObjCInterfaceTypes for declarations. - The two above changes lead to a 0.5% increase in memory use and no speed regression when parsing Cocoa.h. On the other hand, now chained PCH works when there's a forward declaration in one PCH and the interface definition in another. - Add HandleInterestingDecl to ASTConsumer. PCHReader passes the "interesting" decls it finds to this function instead of HandleTopLevelDecl. The default implementation forwards to HandleTopLevelDecl, but ASTUnit's handler for example ignores them. This fixes a potential crash when lazy loading of PCH data would cause ASTUnit's "top level" declaration collection to change while being iterated. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110610 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-07Store inheritance paths after CastExprs instead of inside them.John McCall
This takes some trickery since CastExpr has subclasses (and indeed, is abstract). Also, smoosh the CastKind into the bitfield from Expr. Drops two words of storage from Expr in the common case of expressions which don't need inheritance paths. Avoids a separate allocation and another word of overhead in cases needing inheritance paths. Also has the advantage of not leaking memory, since destructors for AST nodes are never run. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110507 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-06Make sure that we diagnose attribute((overloadable)) functions withoutDouglas Gregor
prototypes. Fixes PR7738. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110443 91177308-0d34-0410-b5e6-96231b3b80d8

found within contexts other than the translation unit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110417 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-01Kill off RequiresGlobalConstructor in favor of isConstantInitializer.John McCall

2010-08-01Make a first pass at implementing -Wglobal-constructors. I'm worried that thisJohn McCall
will end up bizarrely mirroring CGExprConstant, but that might be the hazard of this feature. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@109984 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-01Don't consider all local variables in C++ to mandate scope-checking, justJohn McCall
those with initializers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@109964 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-01Only run the jump-checker if there's a branch-protected scope *and* there'sJohn McCall
a switch or goto somewhere in the function. Indirect gotos trigger the jump-checker regardless, because the conditions there are slightly more elaborate and it's too marginal a case to be worth optimizing. Turns off the jump-checker in a lot of cases in C++. rdar://problem/7702918 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@109962 91177308-0d34-0410-b5e6-96231b3b80d8

qualifiers) when checking a K&R function definition against a previous prototype. Fixes <rdar://problem/8193107>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@109751 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-28Don't set out-of-line template specialization/definition informationDouglas Gregor

2010-07-25Remove the vast majority of the Destroy methods from the AST library,Douglas Gregor
since we aren't going to be calling them ever. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@109377 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-24Be careful; even though we had a proper name at the beginning ofDouglas Gregor
Sema::ActOnDeclarator doesn't mean that the Decl we ended up creating has a useful name. <rdar://problem/8229910> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@109296 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-16Revert Microsoft-specific override of the "typedef requires a name"Douglas Gregor

2010-07-16Add builtin definition for scanf, including extending the builtin encoding toTed Kremenek
represent builtins that have the "scanf" attribution (via the format attribute) just like we do with printf functions. Follow-up work is needed to add similar support for fscanf et al. This is to support format-string checking for scanf functions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108499 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-14When there are extra or missing template parameter lists in a templateDouglas Gregor
definition, we're likely going to end up breaking the invariants of the template system, e.g., that the depths of template parameter lists match up with the nesting template of the template. So, make sure we mark such ill-formed declarations as invalid or don't even build them at all. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108372 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-07Introduce Decl::hasBody() and FunctionDecl::hasBody() and use them instead ↵Argyrios Kyrtzidis
of getBody() when we are just checking the existence of a body, to avoid de-serialization of the body from PCH. Makes de-serialization of the function body even more "lazier". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@107768 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-01Reinstate fix for PR7526, which was failing because, now that weDouglas Gregor
aren't dropping all exception specifications on destructors, the exception specifications on implicitly-declared destructors were detected as being wrong (which they were). Introduce logic to provide a proper exception-specification for implicitly-declared destructors. This also fixes PR6972. Note that the other implicitly-declared special member functions also need to get exception-specifications. I'll deal with that in a subsequent commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@107385 91177308-0d34-0410-b5e6-96231b3b80d8
