2009-07-22Use SaveAndRestore in 'clang/Analysis/Support/SaveAndRestore.h'Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76800 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-22Add AssumeDual method.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76798 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-22Migrate the path-sensitive checking of 'nonnull' arguments over to the newTed Kremenek
'Checker' interface. An updated test case illustrates that after calling a function with the 'nonnull' attribute we now register the fact that the passed pointer must be non-null. This retention of information was not possible with the previously used GRSimpleAPICheck interface. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76797 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-22Fix the parsing of default arguments for inline member function Eli Friedman
definitions. I'm not very familiar with this code, so please review. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76796 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76795 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-22Add support for registering 'Checker' objects with GRExprEngine.Ted Kremenek
Add a 'previsit' stage (that dispatches to registered Checkers) when evaluating the effects of CallExprs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76794 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-22Add new 'Checker' and 'CheckerVisitor' classes, which represent a more powerfulTed Kremenek
interface to plug in domain-specific checker logic than the current GRSimpleAPICheck interface. The new 'Checker' interface can actually generate new nodes, allowing it to modify the state and refine the analysis (which GRSimpleAPIChecks could not). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76793 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-22Add support for 'PreStmt' program points to GRCoreEngine and GRStmtNodeBuilder.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76792 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-22Add 'PreStmt' program point. This will be used to represent checking forTed Kremenek
preconditions (in GRExprEngine) before the statement itself is evaluated. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76791 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-22Fix the problems with template argument deduction and array types forDouglas Gregor
real. It turns out that we need to actually move all of the qualifiers up to the array type itself, then recanonicalize the deduced template argument type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76788 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-22Fix a couple recent ABI regressions noticed during code review (fallout from ↵Steve Naroff
the ObjC type system rewrite). It's unfortunate that the mangling includes the low-level structs. Nevertheless, we need this for binary compatibility with GCC. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76755 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-22Restructure ProgramPoint to have the 'Kind' value be its own instanceTed Kremenek
variable. This gives us much more flexibility with defining more ProgramPoints, which is the direction we are heading. The removal of various bit-mangling of pointers also cleans up the logic. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76721 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-22Temporarily disable most use of region casts in RegionStoreManager,Ted Kremenek
instead preferring to use the a region's actual type when creating symbols and using the QualType passed to Retrieve for implicit casting. This preprocessor logic is temporary; eventually we will either remove region casts or keep them. Temporarily toggle (via preprocessor directives) that SymbolicRegions with heap storage are not undefined, but instead should be symbolicated. If we want to model that a SymbolicRegion is uninitialized, we can explicitly model that by binding UndefinedVal to that region. It turns out that we want to treat most heap objects as being defined, not the other way around. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76720 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-22Fix a crasher in StoreManager::InvalidateRegion() caused by using theTed Kremenek
'cast type' of a region to invalidate its binding. This only occurs when using RegionStoreManager, as it records the cast type. I'm currently considering removing the notion of a cast type (see comments in code). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76719 91177308-0d34-0410-b5e6-96231b3b80d8
