Zhongxing Xu fe97165587 If the UnaryOperator has non-location type, use its type to create the
constant value. If the UnaryOperator has location type, create the
constant with int type and pointer width.

This fixes the bug that all pointer increments 'p++' evaluated to Unknown.

Ted Kremenek fb50bf5a6f Per advice that Doug Gregor gave me several months ago, clean up the
implementation of '#pragma unused' by not constructing intermediate
DeclRefExprs, but instead do the name lookup directly.  The
implementation is greatly simplified.

Along the way, degrade '#pragma unused(undeclaredvariable)' to a
warning instead of being a hard error.  This implements:

<rdar://problem/6761874> [sema] allow #pragma unused to reference undefined variable (with warning)

Ted Kremenek 1f22aa7433 This is a fairly large patch, which resulted from a cascade of changes
made to RegionStore (and related classes) in order to handle some
analyzer failures involving casts and manipulation of symbolic memory.

The root of the change is in StoreManager::CastRegion().  Instead of
using ad hoc heuristics to decide when to layer an ElementRegion on a
casted MemRegion, we now always layer an ElementRegion when the cast
type is different than the original type of the region.  This carries
the current cast information associated with a region around without
resorting to the error prone recording of "casted types" in GRState.

Along with this new policy of layering ElementRegions, I added a new
algorithm to strip away existing ElementRegions when they simply
represented casts of a base memory object.  This algorithm computes
the raw "byte offset" that an ElementRegion represents from the base
region, and allows the new ElementRegion to be based off that offset.
The added benefit is that this naturally handles a series of casts of
a MemRegion without building up a set of redundant ElementRegions
(thus canonicalizing the region view).

Other related changes that cascaded from this one (as tests were
failing in RegionStore):

- Revamped RegionStoreManager::InvalidateRegion() to completely remove
  all bindings and default values from a region and all subregions.
  Now invalidated fields are not bound directly to new symbolic
  values; instead the base region has a "default" symbol value from
  which "derived symbols" can be created.  The main advantage of this
  approach is that it allows us to invalidate a region hierarchy and
  then lazily instantiate new values no matter how deep the hierarchy
  went (i.e., regardless of the number of field accesses,
  e.g. x->f->y->z->...).  The previous approach did not do this.

- Slightly reworked RegionStoreManager::RemoveDeadBindings() to also
  incorporate live symbols and live regions that do not have direct
  bindings but also have "default values" used for lazy instantiation.
  The changes to 'InvalidateRegion' revealed that these were necessary
  in order to achieve lazy instantiation of values in the region store
  with those bindings being removed too early.

- The changes to InvalidateRegion() and RemoveDeadBindings() revealed
  a serious bug in 'getSubRegionMap()' where not all region -> subregion
  relationships involved in actually bindings (explicit and implicit)
  were being recorded.  This has been fixed by using a worklist algorithm
  to iteratively fill in the region map.

- Added special support to RegionStoreManager::Bind()/Retrieve() to handle
  OSAtomicCompareAndSwap in light of the new 'CastRegion' changes and the
  layering of ElementRegions.

- Fixed a bug in SymbolReaper::isLive() where derived symbols were not
  being marked live if the symbol they were derived from was also live.
  This fix was critical for getting lazy instantiation in RegionStore
  to work.

- Tidied up the implementation of ValueManager::getXXXSymbolVal() methods
  to use SymbolManager::canSymbolicate() to decide whether or not a
  symbol should be symbolicated.

- 'test/Analysis/misc-ps-xfail.m' now passes; that test case has been
  moved to 'test/Analysis/misc-ps.m'.

- Tweaked some pretty-printing of MemRegions, and implemented
  'ElementRegion::getRawOffset()' for use with the CastRegion changes.

PathDiagnosticClient now belongs (for now) in AnalysisConsumer.

We also need this layering (for now) because the HTMLDiagnostiClient requires
that the entire translation unit be processed before emitting diagnostics. This
is done in its destructor (which should also be fixed, but that is another
issue).

Eli Friedman e8caa2a72f Remove bogus "unsupported" case for vectors (which shouldn't
ever trigger).  Add an "unsupported" case that triggers for C++ code.

It would be nice if someone would implement this properly... it 
shouldn't be too hard, but I haven't looked closely at the relevant 
code.

Mike Stump 3dc7eb9440 Add ability to layout the vtable pointer in trivial cases. I noticed
that we would silently do bad things with virtual bases in the layout
code, so, we just turn them off.  When people do better things with
them, we can turn them back on.

2009-07-29 23:38:21 +00:00
Douglas Gregor b6b8f9e291 Make tag declarations redeclarable. This change has three purposes:
1) Allow the Index library (and any other interested client) to walk
  the set of declarations for a given tag (enum, union, class,
  whatever). At the moment, this information is not readily available.

  2) Reduce our dependence on TagDecl::TypeForDecl being mapped down
  to a TagType (for which getDecl() will return the tag definition, if
  one exists). This property won't exist for class template partial
  specializations.

  3) Make the canonical declaration of a TagDecl actually canonical,
  e.g., so that it does not change when the tag is defined.

Owen Anderson 9793f0e4d7 Update for LLVM API change.
llvm-svn: 77514
2009-07-29 22:16:19 +00:00
Ted Kremenek c23c7e6a51 Change uses of:
Type::getAsReferenceType() -> Type::getAs<ReferenceType>()
  Type::getAsRecordType() -> Type::getAs<RecordType>()
  Type::getAsPointerType() -> Type::getAs<PointerType>()
  Type::getAsBlockPointerType() -> Type::getAs<BlockPointerType>()
  Type::getAsLValueReferenceType() -> Type::getAs<LValueReferenceType>()
  Type::getAsRValueReferenceType() -> Type::getAs<RValueReferenceType>()
  Type::getAsMemberPointerType() -> Type::getAs<MemberPointerType>()
  Type::getAsReferenceType() -> Type::getAs<ReferenceType>()
  Type::getAsTagType() -> Type::getAs<TagType>()
  
And remove Type::getAsReferenceType(), etc.

This change is similar to one I made a couple weeks ago, but that was partly
reverted pending some additional design discussion. With Doug's pending smart
pointer changes for Types, it seemed natural to take this approach.

llvm-svn: 77510
2009-07-29 21:53:49 +00:00
Ted Kremenek 4301526e8d Remove 'StoreManager::OldCastRegion()', TypedViewRegion (which only

Douglas Gregor aa87ebc0c1 [llvm up]
A template name can refer to a set of overloaded function
templates. Model this in TemplateName, which can now refer to an
OverloadedFunctionDecl that contains function templates. This removes
an unspeakable hack in Sema::isTemplateName.

llvm-svn: 77488
2009-07-29 18:26:50 +00:00
Ted Kremenek 87a7a451ad Remove some uses of TypedViewRegion, and use getBaseRegion() in a context where
we don't care about ElementRegions layered on top of a base region.

llvm-svn: 77484
2009-07-29 18:17:40 +00:00
Ted Kremenek bca70671e7 Make StoreManager::InvalidateRegion() virtual, move the current implementation
in StoreManager to RegionStoreManager, and create a special, highly reduced
version in BasicStoreManager.

These changes are in preparation for future RegionStore-specific changes to
InvalidateRegion.

llvm-svn: 77483
2009-07-29 18:16:25 +00:00
Ted Kremenek ccf3335939 Add 'MemRegion::getBaseRegion()', a utility method to strip ElementRegions with

Douglas Gregor b142c2d0a8 When lookup of an identifier preceding a '<' finds a set of overloaded
functions, only return those overloaded functions that are actually
function templates. Note that there is still a glaring problem with
treating an OverloadedFunctionDecl as a TemplateName.

llvm-svn: 77472
2009-07-29 16:56:42 +00:00

2009-07-29 16:15:53 +00:00
Douglas Gregor 0004417e81 Use the new statement/expression profiling code to unique dependent
template arguments, as in template specialization types. This permits
matching out-of-line definitions of members for class templates that
involve non-type template parameters.

llvm-svn: 77462
2009-07-29 16:09:57 +00:00

Ted Kremenek a41d9dd1f1 Fix PR 4631. The compound initializers of unions were not being evaluated, which

them, but that's an orthogonal problem of whether or not the StoreManager can
handle the binding.

Mike Stump 33979f75a0 Add warning for falling off the end of a function that should return a
value.  This is on by default, and controlled by -Wreturn-type (-Wmost
-Wall).  I believe there should be very few false positives, though
the most interesting case would be:

  int() { bar(); }

when bar does:

  bar() { while (1) ; }

Here, we assume functions return, unless they are marked with the
noreturn attribute.  I can envision a fixit note for functions that
never return normally that don't have a noreturn attribute to add a
noreturn attribute.

If anyone spots other false positives, let me know!

Douglas Gregor e93e46c690 Implement support for out-of-line definitions of the class members of class
templates, e.g.,

  template<typename T>
  struct Outer {
    struct Inner;
  };

  template<typename T>
  struct Outer<T>::Inner {
    // ...
  };

Implementing this feature required some extensions to ActOnTag, which
now takes a set of template parameter lists, and is the precursor to
removing the ActOnClassTemplate function from the parser Action
interface. The reason for this approach is simple: the parser cannot
tell the difference between a class template definition and the
definition of a member of a class template; both have template
parameter lists, and semantic analysis determines what that template
parameter list means.

There is still some cleanup to do with ActOnTag and
ActOnClassTemplate. This commit provides the basic functionality we
need, however.
