2009-03-04Change Parser::ParseCaseStatement to use an iterative approach to parsingChris Lattner
multiple sequential case statements instead of doing it with recursion. This fixes a problem where we run out of stack space parsing 100K directly nested cases. There are a couple other problems that prevent this from being useful in practice (right now the example only parses correctly with -disable-free and doesn't work with -emit-llvm), but this is a start. I'm not including a testcase because it is large and uninteresting for regtesting. Sebastian, I would appreciate it if you could scrutinize the smart pointer gymnastics I do. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66011 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-01ObjCAtCatchStmt's ParamStmt is always a DeclStmt.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65759 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-13Remove DeclGroupOwningRef, since we intend for declarations to be ownedDouglas Gregor
by DeclContexts (always) rather than by statements. DeclContext currently goes out of its way to avoid destroying any Decls that might be owned by a DeclGroupOwningRef. However, in an error-recovery situation, a failure in a declaration statement can cause all of the decls in a DeclGroupOwningRef to be destroyed after they've already be added into the DeclContext. Hence, DeclContext is left with already-destroyed declarations, and bad things happen. This problem was causing failures that showed up as assertions on x86 Linux in test/Parser/objc-forcollection-neg-2.m. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64474 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-07Overhaul of Stmt allocation:Ted Kremenek
- Made allocation of Stmt objects using vanilla new/delete a *compiler error* by making this new/delete "protected" within class Stmt. - Now the only way to allocate Stmt objects is by using the new operator that takes ASTContext& as an argument. This ensures that all Stmt nodes are allocated from the same (pool) allocator. - Naturally, these two changes required that *all* creation sites for AST nodes use new (ASTContext&). This is a large patch, but the majority of the changes are just this mechanical adjustment. - The above changes also mean that AST nodes can no longer be deallocated using 'delete'. Instead, one most do StmtObject->Destroy(ASTContext&) or do ASTContextObject.Deallocate(StmtObject) (the latter not running the 'Destroy' method). Along the way I also... - Made CompoundStmt allocate its array of Stmt* using the allocator in ASTContext (previously it used std::vector). There are a whole bunch of other Stmt classes that need to be similarly changed to ensure that all memory allocated for ASTs comes from the allocator in ASTContext. - Added a new smart pointer ExprOwningPtr to Sema.h. This replaces the uses of llvm::OwningPtr within Sema, as llvm::OwningPtr used 'delete' to free memory instead of a Stmt's 'Destroy' method. Big thanks to Doug Gregor for helping with the acrobatics of making 'new/delete' private and the new smart pointer ExprOwningPtr! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63997 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-27- Move ExprIterator to Stmt.h so that it can be used by classes defined in ↵Ted Kremenek
Stmt.h - Implement child_begin() and child_end() for AsmStmt.

2008-08-11More #include cleaningDaniel Dunbar
- Kill unnecessary #includes in .cpp files. This is an automatic sweep so some things removed are actually used, but happen to be included by a previous header. I tried to get rid of the obvious examples and this was the easiest way to trim the #includes in one fell swoop. - We now return to regularly scheduled development. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54632 91177308-0d34-0410-b5e6-96231b3b80d8

2008-05-20Try to plug some memory leaks...Ted Kremenek
1) Sema::ParseAST now constructs a TranslationUnit object to own the top-level Decls, which releases the top-level Decls upon exiting ParseAST. 2) Bug fix: TranslationUnit::~TranslationUnit handles the case where a Decl is added more than once as a top-level Decl. 3) Decl::Destroy is now a virtual method, obviating the need for a special dispatch based on DeclKind. 3) FunctionDecl::Destroy now releases its Body using its Destroy method. 4) Added Stmt::Destroy and Stmt::DestroyChildren, which recursively delete the child ASTs of a Stmt and call their dstors. We may need to special case dstor/Destroy methods for particular Stmt subclasses that own other dynamically allocated objects besides AST nodes. 5) REGRESSION: We temporarily are not deallocating attributes; a FIXME is provided. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51286 91177308-0d34-0410-b5e6-96231b3b80d8
