Get rid of the EndOfPathBuilder completely.
Use the generic NodeBuilder to generate nodes.
Enqueue the end of path frontier explicitly.

statements. As noted in the documentation for the AST node, the
semantics of __if_exists/__if_not_exists are somewhat different from
the way Visual C++ implements them, because our parsed-template
representation can't accommodate VC++ semantics without serious
contortions. Hopefully this implementation is "good enough".

This commit removes the major functional dependency on the ExprEngine::Builder
member variable.
In some cases the code became more verbose. Particularly, we call takeNodes()
and addNodes() to move responsibility for the nodes from one builder to another.
This will get simplified later on.
llvm-svn: 142831
To convert iteratively, we take the nodes the local builder will
process from the from the global builder and add the generated nodes
after the short lived builder is done. PureStmtNodeBuilder is the
one we should eventually use everywhere. Added Stmt index and Builder
context as ExprEngine globals. To avoid passing them around.
llvm-svn: 142828
First step toward removing the global Stmt builder. Added several transitional methods (like takeNodes/addNodes).
+ Stop early if the set of exploded nodes for the next iteration is empty.
llvm-svn: 142827
This moves the responsibility for storing the output node set from the
builder to the clients. The builder is just responsible for transforming
an input set into the output set: {SrcSet/SrcNode} -> {Frontier}.
llvm-svn: 142826
NodeBuilder should not assume it's dealing with a single predecessor. Remove predecessor getters. Modify the BranchNodeBuilder to not be responsible for doing auto-transitions (which depend on a predecessor).
llvm-svn: 142453
Take advantage of the new builders for branch processing. As part of this change pass generic NodeBuilder (instead of BranchNodeBuilder) to the BranchCondition callback and remove the unused methods form BranchBuilder.

Remove TransferFuncs from ExprEngine and AnalysisConsumer.
Demote RetainReleaseChecker to a regular checker, and give it the name osx.cocoa.RetainCount (class name change coming shortly). Update tests accordingly.

Unlike the other callbacks, this one is a simple virtual method, since it is only to be used for debugging.
This new callback replaces the old ProgramState::Printer interface, and allows us to move the printing of refcount bindings from CFRefCount to RetainReleaseChecker.
llvm-svn: 138728
Also, allow CallOrObjCMessage to wrap a CXXConstructExpr as well.
Finally, this allows us to remove the clunky whitelisting system from CFRefCount/RetainReleaseChecker. Slight regression due to CXXNewExprs not yet being handled in post-statement callbacks (PR forthcoming).

Having a notion of an actual ProgramPointTag will aid in introspection of the analyzer's behavior.
For example, the GraphViz output of the analyzer will pretty-print the tags in a useful manner.
