Expand checking to include functions, not just methods.

Use this updated interface when invalidating arguments passed by reference; the type of symbol is of the object passed by reference, not the reference itself.

Move VLA processing logic from LiveVariables to CFG construction.  This way all dataflow analyses "see" the VLA size expressions.

Changed casing of many bug names.  The convention will be to have bug names (mostly) lower cased, and categories use some capitalization.

GRExprEngine:
  Use PostStore in EvalStore.
  Use a second version of EvalStore in EvalBinaryOperator to associate the store with the expression on the LHS.

Bug fix: for the base transfer function logic for casts, handle const casts as just propagating the value.

llvm-svn: 56368

For checking if a symbol >= value, we need to check if symbol == value || symbol
> value. When checking symbol > value and we know that symbol != value, the path
is infeasible only if value == maximum integer.

For checking if a symbol <= value, we need to check if symbol == value || symbol
< value. When checking symbol < value and we know that symbol != value, the path
is infeasible only if value == minimum integer.

Updated test case exercising this logic: we only prune paths if the values are
unsigned.

'symbol operator-reverse int'. This patch is a combination of code from
Zhongxing Xu and myself (Zhongxing noticed this bug for the cases of
relational operators).

Implement second part of PR 2600: NSError** parameter may be null, and should be checked before being dereferenced.

llvm-svn: 56318

Change implementation of NSError** coding-style check to be invoked at the end of the retain/release analysis.

"Method accepting NSError** argument should have non-void return value to indicate that an error occurred."

Test case written, but the header needs to be delta-debugged reduced.  Will commit shortly.

  if we know that 'len != 0' and know that 'i == 0' then we know that
  'i < len' must evaluate to true and cannot evaluate to false

motivated because it became clear that the number of subclasses of ProgramPoint
would expand and we ran out of bits to represent a pointer variant. As a plus of
this change, BlockEdge program points can now be represented explicitly without
using a cache of CFGBlock* pairs in CFG.

"Here is a patch what replaces std::ostream with llvm::raw_ostream. This patch

- Change definition of store::Region and store::Binding (once again) to make
  them real classes that just wrap pointers. This makes them more strictly
  typed, and allows specific implementations of Regions/Bindings to just
  subclass them.
- minor renamings to RegionExtent and its subclasses
- added a bunch of doxygen comments

StoreManager: (static analyzer)
- added 'iterBindings', an iteration method for iterating over the bindings of a
  store. It that takes a callback object (acting like a poor man's closure).
- added 'getRVal' version for store::Binding. Will potentially phase the other
  versions of GetRVal in StoreManager out.
- reimplemented 'getBindings' to be non-virtual and to use 'iterBindings'

BasicStoreManager: (static analyzer)
- implemented 'iterBindings' for BasicStoreManager

Migrated CFRefCount.cpp to use getBindings and BindingsAsString instead of
making assumptions about the Store (removed dependence on GRState::vb_iterator).

Remove Regions.h and Regions.cpp, since we are now using an even more abstract representation of "memory regions" in the static analyzer.

Their precise semantics will be implemented by a specific StoreManager.

Use function pointer to create the StoreManager in GRStateManager.  This matches how we create ConstraintsManager.
