* Change Parser::ParseCaseStatement to use an iterative approach to parsingChris Lattner2009-03-041-5/+4
| | | | | | | | | | | | | | | | | | 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. llvm-svn: 66011

* ObjCAtCatchStmt's ParamStmt is always a DeclStmt.Daniel Dunbar2009-03-011-1/+2
| | | | llvm-svn: 65759
* Remove DeclGroupOwningRef, since we intend for declarations to be ownedDouglas Gregor2009-02-131-1/+0
| | | | | | | | | | | | | | | 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. llvm-svn: 64474
* Overhaul of Stmt allocation:Ted Kremenek2009-02-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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! llvm-svn: 63997
* Use ASTContext's allocator to deallocate Stmt objects instead of using ↵Ted Kremenek2009-02-061-3/+5

* Don't require us to manually number the statements and expressions in ↵Douglas Gregor2008-11-141-3/+3
| | | | | | StmtNodes.def. We don't need stable numbers yet, renumbering is a pain, and LAST_STMT had the wrong value anyway. llvm-svn: 59300
* - Move ExprIterator to Stmt.h so that it can be used by classes defined in ↵Ted Kremenek2008-10-271-2/+19
| | | | | | | | | Stmt.h - Implement child_begin() and child_end() for AsmStmt. Previously these had stub implementations that did not iterate over the input/output operands of an inline assembly statement. - Use ExprIterator for performing iteration over input/output operands. llvm-svn: 58261
* Migrate DeclStmt over to using a DeclGroup instead of a pointer to a ↵Ted Kremenek2008-10-071-9/+5
| | | | | | | | ScopedDecl*. This also removes the ugly hack needed in CFG.cpp for subclassing DeclStmt to create a DeclStmt with one Decl*. llvm-svn: 57275
* Add DeclStmt::hasSolitaryDecl() and DeclStmt::getSolitaryDecl()Ted Kremenek2008-10-061-1/+5
| | | | llvm-svn: 57204
* More #include cleaningDaniel Dunbar2008-08-111-2/+0
| | | | | | | | | | | - 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. llvm-svn: 54632
* remove spaces at eol to test commit accessNico Weber2008-08-051-23/+23
| | | | llvm-svn: 54381
* Added decl_iterator to DeclStmt to provide an abstract interface to iterate ↵Ted Kremenek2008-08-051-0/+5
| | | | | | | | over the ScopedDecls of a DeclStmt. Updated a few clients of DeclStmt::getNextDeclarator() to use decl_iterator instead. Will update other clients after additional testing. llvm-svn: 54368

* Try to plug some memory leaks...Ted Kremenek2008-05-201-2/+7
| | | | | | | | | | | | | | | | 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. llvm-svn: 51286

* Make a major restructuring of the clang tree: introduce a top-levelChris Lattner2008-03-151-0/+293
lib dir and move all the libraries into it. This follows the main llvm tree, and allows the libraries to be built in parallel. The top level now enforces that all the libs are built before Driver, but we don't care what order the libs are built in. This speeds up parallel builds, particularly incremental ones. llvm-svn: 48402
