5d5efca405 -Add missing visitor for ObjCIvarRefExpr. 
-Wrap objc runtime calls with "extern "C"" (for now).

4182fd56ad Since the rewriter now outputs C++, it no longer makes sense to pipe the output to clang. 
This should "fix" all but one of the test failure.

dc5b6b2e5d Make ivar rewrite C++ friendly (since C++ forces a unified namespace for typedefs/structures). The previous version of the rewriter generated both a type def and structure def for each class (which doesn't fly in C++).

3e4683262e implement simple support for arbitrary token lookahead. Change the 
objc @try parser to use it, fixing a FIXME.  Update the 
objc-try-catch-1.m file to pass now that we get more reasonable 
errors.

a34cf6de66 More edge-case handling with using liveness information to prune dead state values. 
llvm-svn: 48127
 2008-03-10 04:45:00 +00:00
Ted Kremenek
b73a43cc01 More cleanups with using the liveness analysis to removed dead symbols and 
variables from the symbolic state. Now we keep a mapping from the predecessor
node of a statement and its cleaned state, and interpose an accessor
"GetState()" to return the cleaned state when the node is the predecessor node,
and the real state otherwise. This obviates problem of ever accidentally
cleaning the state more than once (thus blowing away new bindings by mistake).

6c50479737 When processing the transfer function for a statement, evaluate 
RemoveDeadBindings early because (1) it will always be called and (2) we can
dispatch to a plug-in transfer function that can evaluate the effect of dead
symbols (not yet added).

2d063bef8b Refactored guards for "GRExprEngine::RemoveDeadBindings" directly into the 
method. This paves the way for other alterations to RemoveDeadBindings that are
transparent to its callers.

cfd8b19ef7 Bug fix in the transfer function for compound assignments: if the value 
of the LHS expressions is Unknown, the value of the entire expression
does not evaluate to the RHS (as is the case with normal assignments).

token streams and macro lexing, so a more generic name is useful.
