2009-02-28"This patch addresses two FIXME on ObjCCategoryImplDecl:Chris Lattner
/// FIXME: Like ObjCImplementationDecl, this should not be a NamedDecl! /// FIXME: Introduce a new common base class for ObjCImplementationDecl and ObjCCategoryImplDecl It adds an IndentifierInfo ivar to the ObjCCategoryImplDecl, so it can inherits from Decl and not NamedDecl (I'm not sure about the memory management of this ivar). And now that both ObjCImplementationDecl and ObjCCategoryImplDecl have the same super classes, it allow creation of a common base class: ObjCImplDecl" Patch by Jean-Daniel Dupas! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65703 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-28after going around in circles a few times, finally cave and emit structureChris Lattner
copies with memcpy instead of memmove. This matches what GCC does and if it causes a problem with a particular libc we can always fix it with a target hook. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65699 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-28Fix <rdar://problem/6451399> problems with labels and blocks.Steve Naroff
- Move the 'LabelMap' from Sema to Scope. To avoid layering problems, the second element is now a 'StmtTy *', which makes the LabelMap a bit more verbose to deal with. - Add 'ActiveScope' to Sema. Managed by ActOnStartOfFunctionDef(), ObjCActOnStartOfMethodDef(), ActOnBlockStmtExpr(). - Changed ActOnLabelStmt(), ActOnGotoStmt(), ActOnAddrLabel(), and ActOnFinishFunctionBody() to use the new ActiveScope. - Added FIXME to workaround in ActOnFinishFunctionBody() (for dealing with C++ nested functions). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65694 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-28Check a few more kinds of declarations that make a scope.Eli Friedman
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65680 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-28Start of checking for gotos which jump to an illegal destination. Eli Friedman
As far as I know, this catches all cases of jumping into the scope of a variable with a variably modified type (excluding statement expressions) in C. This is missing some stuff we probably want to check (other kinds of variably modified declarations, statement expressions, indirect gotos/addresses of labels in a scope, ObjC @try/@finally, cleanup attribute), the diagnostics aren't very good, and it's not particularly efficient, but it's a decent start. This patch is a slightly modified version of the patch I attached to PR3259, and it fixes that bug. I was sort of planning on improving it, but I think it's okay as-is, especially since it looks like CodeGen doesn't have any use for this sort of data structure. The only significant change I can think of from the version I attached to PR3259 is that this version skips running the checking code when a function doesn't contain any labels. This patch doesn't cover case statements, which also need similar checking; I'm not sure how we should deal with that. Extending the goto checking to also check case statements wouldn't be too hard; it's just a matter of keeping track of the scope of the closest switch and checking that the scope of every case is the same as the scope of the switch. That said, it would likely be a performance hit to run this check on every function (it's an extra pass over the entire function), so we probably want some other solution. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65678 91177308-0d34-0410-b5e6-96231b3b80d8

natural alignment. Otherwise, the excess hole confuses the objc2 runtime (this is darwin specific). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65666 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-28Implement template instantiation for pointer, reference, and (some)Douglas Gregor
array types. Semantic checking for the construction of these types has been factored out of GetTypeForDeclarator and into separate subroutines (BuildPointerType, BuildReferenceType, BuildArrayType). We'll be doing the same thing for all other types (and declarations and expressions). As part of this, moved the type-instantiation functions into a class in an anonymous namespace. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65663 91177308-0d34-0410-b5e6-96231b3b80d8
