analyzer to analyze functions declared in header files.

Ted Kremenek 4a78c3ae11 Refactored all logic to run the GRSimpleVals and CFRef checker into a common
code path in the clang driver.

Renamed options --grsimple to -checker-simple and -check-cfref to -checker-cfref.

Ted Kremenek c27815ca82 Inlined clang/Analysis/Analyses/GRSimpleVals.h into LocalCheckers.h and removed
GRSimpleVals.h

Added a PathDiagnosticClient option to the driver functions for the
CFRefCountChecker and the GRSimpleVals analysis. Both analyses now accept a "-o"
argument from the driver that specifies where HTML reports should be dumped.

Ted Kremenek 7b00d15bc5 Path-sensitive analyses no longer take a FunctionDecl, but any Decl representing
a block of "code".

Patched various ASTConsumers (such as ASTDumper) to have more support for
processing ObjCMethodDecl. CFGVisitor now builds CFGs for ObjCMethodDecls.

llvm-svn: 48363
2008-03-14 17:31:00 +00:00
Ted Kremenek 1fdd0a480e The LiveVariables analysis no longer requires a FunctionDecl&; this allows it
to be run on other declarations of blocks of code (e.g., Objective-C methods.)

llvm-svn: 48339
2008-03-13 16:55:07 +00:00
Ted Kremenek b64d183803 Added bandaid support in CFG construction for ObjCForEachStmt and ObjCAtTryStmt:
we gracefully back out and return NULL for the CFG, allowing clients to skip
analyzing functions with these CFGs. We will add support later.

Modified base ASTConsumer "CFGVisitor" to detect when a CFG is not constructed
and to emit a warning.

llvm-svn: 48322
2008-03-13 03:04:22 +00:00
Ted Kremenek 2bdd77696e Added --trim-path-graph to the driver to trim paths from the ExplodedGraph
that are not related to error nodes.

Fixed bug where we did not detect some NULL dereferences.

Added "ExplodedGraph::Trim" to trim all nodes that cannot transitively reach
a set of provided nodes.

Fixed subtle bug in ExplodedNodeImpl where we could create predecessor
iterators that included the mangled "sink" bit.  The better fix is to integrate
this bit into the void* for the wrapped State, not the NodeGroups representing
a node's predecessors and successors.

Ted Kremenek ea6507fe04 Added boilerplate to execute the CF reference count checker (which isn't yet implemented).

Ted Kremenek c77f34daad Modified clang driver option -dump-live-variables to (optionally) use the
--analyze-function option to analyze specific functions.

llvm-svn: 47498
2008-02-22 20:13:09 +00:00
Ted Kremenek 88329bf0ea clang driver options --dump-cfg and --view-cfg now (optionally) use the
--analyze-function option to dump/view the CFGs of specific functions.

llvm-svn: 47497
2008-02-22 20:00:31 +00:00
Ted Kremenek 76c03b4a55 When running the GRSimpleVals analysis, skip functions that do not
appear in a file.

Ted Kremenek dbb1a3724c For now, --grsimple skips analyzing functions in header files.
llvm-svn: 47303
2008-02-19 02:33:31 +00:00
Ted Kremenek 0f7130adc4 --grsimple now reports the number of nodes in the ExplodedGraph for
an analyzed function.

GRExprEngine now records stores to "uninitialized lvalues" (which are sinks in
the ExplodedGraph).

llvm-svn: 47293
2008-02-19 00:22:37 +00:00
Ted Kremenek 86e793937a Running -grsimple now emits diagnostics about the time spent analyzing each function. Will
probably make this a separate command line option later.

Added "--analyze-function" option to the driver to (gradually) allow different
analyses to only be run on specific functions. Currently only --grsimple uses
this option.

llvm-svn: 47285
2008-02-18 21:21:23 +00:00
Ted Kremenek e161afc4dd Added --grsimple-view option to clang driver; this is the same as
--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.

llvm-svn: 47146
2008-02-15 00:35:38 +00:00
Ted Kremenek d3122cb83c Renamed GRConstants => GRSimpleVals.

Ted Kremenek d74da0838f Added proof-of-concept NULL pointer diagnostics to GRConstants.
Modified the driver to pass the Diagnostic object to GRConstants.

2008-02-07 06:33:19 +00:00
Chris Lattner adf1f51fc5 move the codegen ASTConsumer out of the driver into libcodegen,
eliminating a bunch of forwarding methods and generally 
simplifying things.

Chris Lattner b5eda6253b pull .ll and .bc writing out of the ASTConsumer destructors into some top
level code in clang.  This is a cleanup, but does implement "-o" for 
-emit-llvm.  One effect of this is that "clang foo.c -emit-llvm" will now
emit into foo.ll instead of stdout.  Use "clang foo.c -emit-llvm -o -" or 
"clang < foo.c -emit-llvm" to get the old behavior.

Chris Lattner b1537ebdd4 rewrite some of the type refinement code to eliminate dangling pointers
simplify the code and generally make it more robust.

2008-02-05 08:06:13 +00:00
Ted Kremenek 8ff7705a6c Modified LiveVariables to perform all of its base initialization in the ctor,
and now we require a FunctionDecl* object so that we can also keep track of
all of the ParmDecls.

Modified clients of LiveVariables to conform to the new interface.

Ted Kremenek 997d872375 Driver now passes the top-level FunctionDecl* to GRConstants.
Refactoring: for GREngine and GRConstants, pushed references to CFG, ASTContext,
and the top-level FunctionDecl into ExplodedGraphImpl.

llvm-svn: 46475
2008-01-29 00:33:40 +00:00
Ted Kremenek 33d8285b8d Added passing "ASTContext" to both GREngine and GRConstants.

2008-01-24 02:02:54 +00:00
Ted Kremenek 2e12c2e790 Hooked up the GRConstants analysis to the driver.

template instantiation.

constant propagation analysis.

2008-01-08 18:04:06 +00:00
Ted Kremenek 1b0ea82459 Substituted all instances of the string "Objc" for "ObjC". This fixes
some naming inconsistencies in the names of classes pertaining to Objective-C
support in clang.
