2007-12-17Fixed another case where sizeof() returns the size in bytes, not bits.Ted Kremenek
This parallels a previous patch (duplicate logic caused the bug to appear in multiple locations): r44316 (http://llvm.org/viewvc/llvm-project?rev=44316&view=rev). Patch provided by Nuno Lopes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45098 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-15Removed "isSizeOfExpr" mode from StmtIterator. It turned out not to beTed Kremenek
so useful and introduced a few bugs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45051 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-14Added "mode" to StmtIterator to record if the expression being iteratedTed Kremenek
over is the subexpression of a sizeof(expression). Different clients will wish to handle iteration over such subexpressions differently, and can now easily query if they are iterating over such statements using the StmtIterator's inSizeOfExpr(). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45047 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-14- Remove getInstanceMethods/getClassMethods API on ObjcInterfaceDecl, ↵Steve Naroff
ObjcProtocolDecl, and ObjcCategoryDecl. These methods are replaced by the respective iterators on each class. - Add getInstanceMethodForSelector to ObjcInterfaceDecl, ObjcProtocolDecl, and ObjcCatgoryDecl. This hook will do a "shallow" lookup. This is a convenience method that reducing some of the iterator usage. - Various changes to convert all clients to the above API's... git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45046 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-14Added support to StmtIterator to traverse the size expression of a VLA typeTed Kremenek
declared in a sizeof. For example: sizeof(int[foo()]); the expression "foo()" is an expression that is executed during the evaluation of sizeof. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45043 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-13CFG bug fix: for sizeof(expressions), don't expand the control-flowTed Kremenek

2007-12-13Updated serialization of ParmVarDecl to serialize out objcDeclQualifier.Ted Kremenek
Previously this field was serialized out in VarDecl (a parent class), but now the field belongs to ParmVarDecl. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44989 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-13Moved ObjcDeclQualifier to ParmVarDecl from VarDecl.Fariborz Jahanian
Ted, this change necessitates (de)/serialization of ParmVarDecl. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44972 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-12TargetInfo no longer includes a reference to SourceManager.Ted Kremenek
Moved all clients of Diagnostics to use FullSourceLoc instead of SourceLocation. Added many utility methods to FullSourceLoc to provide shorthand for: FullLoc.getManager().someMethod(FullLoc.getLocation()); instead we have: FullLoc.someMethod(); Modified TextDiagnostics (and related classes) to use this short-hand. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44957 91177308-0d34-0410-b5e6-96231b3b80d8

2007-12-12Added back VisitDeclStmt() to the StmtDumper, essentially reverting r44920:Ted Kremenek
http://llvm.org/viewvc/llvm-project?rev=44920&view=rev Putting VisitDeclStmt() was motivated because it called DumpDeclarator(), which printed out a little bit more information than just using the child_iterator interface to visit the subexpressions of DeclStmt. To avoid printing the initializers twice, DumpSubTree() now specially checks for DeclStmts; in such cases it calls VisitDeclStmt() without using the child_iterators to visit the subexpressions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44924 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-12Removed VisitDeclStmt(). The initializers of a DeclStmt are now automaticallyTed Kremenek
printed out by DumpSubTree() via the child_iterator interface. This fixes a bug where the initializers were being dumped twice. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44920 91177308-0d34-0410-b5e6-96231b3b80d8

2007-12-12Implemented type checking for pointer of objects of protocol-qualified types.Fariborz Jahanian

2007-12-10Fixed bug in CFG::PopulateBlkExprMap where the orderingTed Kremenek
between fetching the size of the expression map (for use as the next integer id for an Expr*) and the creation of the entry in the map could be non-deterministic. This could cause the size of the map to be incremented prior to the index being determine. On Linux the map entry would be created first, causing the map to the "size" to be incremented prior to it being queried. On Mac OS X we had the reverse behavior. Now the size is always queried prior to the new id being inserted into the map. This was the real cause of the bit-overrun triggered in PR 1847: http://llvm.org/bugs/show_bug.cgi?id=1847 Also reverted the change in patch 44813, which was a bogus fix to this problem: http://llvm.org/viewvc/llvm-project?rev=44813&view=rev git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44822 91177308-0d34-0410-b5e6-96231b3b80d8

2007-11-29Added method "HandleTopLevelDeclaration" to ASTConsumer. This will eventuallyTed Kremenek
be the new hook that ASTStreamer calls to feed top-level Decls to ASTConsumers. The difference between "HandleTopLevelDeclaration" and "HandleTopLevelDecl" is that "HandleTopLevelDecl" is currently called by ASTStreamer for every top-level declaration, including those that appear within a Decl chain. Using the new interface, ASTStreamer would only call HandleTopLevelDeclaration for Decls that appear that the beginning of a Decl chain (i.e., a group of related decls). To preserve the behavior that all subclasses of ASTConsumer currently expect, the default implementation of HandleTopLevelDeclaration simply calls HandleTopLevelDecl, and for decl chains it calls HandleTopLevelDecl for each Decl* in a chain of Decls. The advantage of this interface is that some subclasses of ASTConsumer only really want the Decl chain, and not each individual Decl passed to them. This extra level of indirection allows subclasses to override the default behavior if they so desire. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44444 91177308-0d34-0410-b5e6-96231b3b80d8
