Fixed bug in transfer functions for sizeof(*); we were incorrectly evaluating to
a value of the wrong type.

Fixed bug in transfer functions for compound assignments where we did not properly
handle assignments involving dereferences of symbolic values.

llvm-svn: 47190

Fixed bug in transfer function for compound assignment operators when both operands where variables but had a non-pointer type (we fired an assertion).

llvm-svn: 47184

Added more boilerplate transfer function support for pointer arithmetic.
Added more pretty-printing support for symbolic constraints.
Added transfer function support for handling enum values.
Minor pointer types cleanup in ExplodedGraphImpl.

--grsimple except that it visualizes the ExplodedGraph using dot and
outputs the current function being analyzed.  --grsimple is now silent
except when it emits diagnostics.

Modified ValueState::RemoveDeadBindings to also prune dead symbols.

Moved driver logic for --grsimple to GRSimpleVals.cpp.

Still some cleanup to do, but this initial checkin compiles and runs correctly.

these operations) into GRTransferFuncs and its subclasses.  Originally all
of this logic was handled by the class RValue, but in reality different
analyses will want more flexibility on how they evaluate different values.

Transfer functions migrated so far: "Cast"

Renamed class GRConstants => GRExprEngine.

This was done with a Perl script, and will result in 80 col. violations that
I will gradually fix up.

casting them to lval::SymbolVal.

Reordered some cases in the switch statement of GRConstant::Visit() so
that they are ordered alphabetically based on AST node type.

llvm-svn: 47021

Added transfer function support for CharacterLiteral.

enqueued to the worklist.

Modified "ProcessBranch" in GRConstants to prune branches with symbolic
conditions that have been already taken.

Fixed a horrible bug in lval:DeclVar::classof(RValue* V); we weren't checking
V was an LValue, allowing nonlval::ConcereteInts to match isa<lval::DeclVar>.

bindings for block-level expressions.

Moved pretty-printing logic (DOT) for ValueStates to ValueState.cpp.

llvm-svn: 46965

llvm-svn: 46892

Expr* instead of a Stmt*, since we only
store bindings for Expr*.

llvm-svn: 46891

GRConstants logic to ValueStateManager.

Fixed bug in dispatching to the correct transfer function for |=, &=, and ^|.

Renamed UninitializedValue to UninitializedVal.
