2009-06-30Update old CastRegion logic to not assume that ElementRegion's super region is aTed Kremenek
TypedRegion. While we plan on removing this code at some point, it serves as a good reference implementation for use with BasicStore until we are sure the new CastRegion logic (in RegionStore.cpp) is correct. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74559 91177308-0d34-0410-b5e6-96231b3b80d8

Mark the super region of the binding of block level expr in the Environment as live. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74525 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-30When retrieving element region, if its super region has binding, returnZhongxing Xu
unknown for it. Mark the super region of a live region as live, if the live region is pointed to by a live pointer variable. These fixes xfail_regionstore_wine_crash.c. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74524 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-30Block level expr should be visited. Otherwise variables in init expr ofZhongxing Xu
DeclStmt would be dead before the DeclStmt. For example: int x = 0; int y = x; 'x' would be dead before 'int y = x'. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74522 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-30De-ASTContext-ify DeclContext.Argyrios Kyrtzidis
Remove ASTContext parameter from DeclContext's methods. This change cascaded down to other Decl's methods and changes to call sites started "escalating". Timings using pre-tokenized "cocoa.h" showed only a ~1% increase in time run between and after this commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74506 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-30Remove the ASTContext parameter from the getBody() methods of Decl and ↵Argyrios Kyrtzidis
subclasses. Timings showed no significant difference before and after the commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74504 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-30Remove the ASTContext parameter from the attribute-related methods of Decl.Argyrios Kyrtzidis
The implementations of these methods can Use Decl::getASTContext() to get the ASTContext. This commit touches a lot of files since call sites for these methods are everywhere. I used pre-tokenized "carbon.h" and "cocoa.h" headers to do some timings, and there was no real time difference between before the commit and after it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74501 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-30Key decisions about 'bool' vs '_Bool' to be based on a new flag in langoptions.Chris Lattner
This is simple enough, but then I thought it would be nice to make PrintingPolicy get a LangOptions so that various things can key off "bool" and "C++" independently. This spiraled out of control. There are many fixme's, but I think things are slightly better than they were before. One thing that can be improved: CFG should probably have an ASTContext pointer in it, which would simplify its clients. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74493 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-26Introduce a new concept to the static analyzer: SValuator.Ted Kremenek
GRTransferFuncs had the conflated role of both constructing SVals (symbolic expressions) as well as handling checker-specific logic. Now SValuator has the role of constructing SVals from expressions and GRTransferFuncs just handles checker-specific logic. The motivation is by separating these two concepts we will be able to much more easily create richer constraint-generating logic without coupling it to the main checker transfer function logic. We now have one implementation of SValuator: SimpleSValuator. SimpleSValuator is essentially the SVal-related logic that was in GRSimpleVals (which is removed in this patch). This includes the logic for EvalBinOp, EvalCast, etc. Because SValuator has a narrower role than the old GRTransferFuncs, the interfaces are much simpler, and so is the implementation of SimpleSValuator compared to GRSimpleVals. I also did a line-by-line review of SVal-related logic in GRSimpleVals and cleaned it up while moving it over to SimpleSValuator. As a consequence of removing GRSimpleVals, there is no longer a '-checker-simple' option. The '-checker-cfref' did everything that option did but also ran the retain/release checker. Of course a user may not always wish to run the retain/release checker, nor do we wish core analysis logic buried in the checker-specific logic. The next step is to refactor the logic in CFRefCount.cpp to separate out these pieces into the core analysis engine. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74229 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-23- Add MemRegion::getMemorySpace()Ted Kremenek
- Change implementation of MemRegion::hasStackStorage()/hasHeapStorage() to use 'getMemorySpace()'.
