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

appear in a file.

Ted Kremenek dbb1a3724c For now, --grsimple skips analyzing functions in header files.

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).

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.

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.

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.

Created include/clang/Analysis/Analyses directory.
  - Moved LiveVariables.h and UninitializedValues.h into this dir.

Ted Kremenek 371efafb94 Created initial implementation of "BuildSerializer", and ASTConsumer
which serializes ASTs to a common output directory.  This ASTConsumer
is invoked using a combination of "-o" and "-serialize" from the driver.

llvm-svn: 45241
2007-12-20 00:34:58 +00:00
Ted Kremenek ca07147851 Split serialization ASTConsumers into two consumers: SingleFileSerializer and
BuildSerializer. The former serializes a single translation unit to a
corresponding .ast file. The second serializes ASTs to a common emission
direction.  The latter is not fully implemented yet.

llvm-svn: 45232
2007-12-19 23:49:37 +00:00
Ted Kremenek 230bd918b2 Interned MainFileID within SourceManager. Since SourceManager is referenced by
both Preprocessor and ASTContext, we no longer need to explicitly pass
MainFileID around in function calls that also pass either Preprocessor or
ASTContext. This resulted in some nice cleanups in the ASTConsumers and the
driver.

llvm-svn: 45228
2007-12-19 22:51:13 +00:00
Ted Kremenek 6c7807716b Removed "SourceFile" from TranslationUnit. This same information will (soon)
be available by querying the SourceManager within the ASTContext referenced by
the TranslationUnit.

llvm-svn: 45223
2007-12-19 22:24:34 +00:00
Ted Kremenek 0061aeb316 Removed storing inode and device number in TranslationUnit.
Added "SourceFile" string to TranslationUnit to record corresponding
source file.

Updated serialization of TranslationUnits and logic in the driver to
correctly pass the source file information to the serializer.

llvm-svn: 45211
2007-12-19 19:27:38 +00:00
Ted Kremenek 6c3777c319 Moved generation of the name of the serialized AST file into
CreateASTSerializer.

2007-12-19 17:25:59 +00:00
Ted Kremenek f70d24d2ae Moved ReadBitcodeFile and EmitBitcodeFile out of TranslationUnit and made them
the standalone functions ReadASTBitcodeFile and EmitASTBitcodeFile
respectively.

llvm-svn: 45180

Ted Kremenek 15ddcef648 Changed -serialize-ast to not create a temporary directory, but instead
create a .ast file in the current working directory.  This mirrors the behavior
of the -c option for gcc.  Later we should add the ability to write the
serialized file anywhere.

Ted Kremenek d4e5fbacab Mega-patch: ripped SourceManager out of Diagnostic/DiagnosticClient. Now
SourceManager is passed by reference, allowing the SourceManager to be
associated with a specific translation unit, and not the entire execution
of the driver.

Modified all users of Diagnostics to comply with this new interface.

Integrated SourceManager as a member variable of TargetInfo. TargetInfo will
eventually be associated with a single translation unit (just like
SourceManager).

Made the SourceManager reference in ASTContext private. Provided accessor
getSourceManager() for clients to use instead. Modified clients to comply with
new interface.
