Fariborz Jahanian ec6e4c8096 This patch introduces declaration of getter methods for ObjC2's
properties. Couple of property tests will fail with this patch.
Will fix them next.

Fariborz Jahanian 09367d68ff Patch to refactor setter/getter names of property attributes into Selector
(was IdentifierInfo * before). This will make method declartations whole
lot easier.

Ted Kremenek 789942cfda When running the reference count checker twice (GC and non-GC mode), only emit
basic warnings (dead stores, null dereferences) on the first pass.

2008-05-02 18:01:49 +00:00
Ted Kremenek b0f87c48cb added preliminary diagnostics in scan-build results to denote whether
a CF memory leak occurred with GC enabled, etc.

llvm-svn: 50507
2008-04-30 23:47:44 +00:00
Ted Kremenek 4d1f422c6f Provide the option to run the CF-retain checker in GC enabled mode.
The transfer functions for the checker don't do anything special yet in GC mode.

Ted Kremenek 467297ab48 TranslationUnit now owns IdentifierTable, TargetInfo, and Selectors objects
when it is constructed via deserialization.  This is done by recording a flag
indicating that this is the case, and it deletes these objects by getting
the references stored in the ASTContext object.  This fixes some memory
leaks that occurs when we deserialize translation units from bitcode files.

The rationale between having TranslationUnit sometimes own these objects and
sometimes not is that a TranslationUnit object can be constructed from
state generated by the parser (Preprocessor; semantic analyzer, etc.), and thus
in these cases won't own the IdentifierTable or Selectors, etc.  During
deserialization, there is no Preprocessor, so somebody needs to own these
objects in order for them to be properly reclaimed.

2008-04-23 16:25:39 +00:00
Fariborz Jahanian 6efdf1ddab Patch to build AST for property implementation declarations and
to print declaration from its AST.

llvm-svn: 50117
2008-04-23 00:06:01 +00:00
Ted Kremenek f42f3fb47d class Preprocessor: Now owns the "predefines" char*; it deletes [] it in its dstor.
clang.cpp: InitializePreprocessor now makes a copy of the contents of PredefinesBuffer and
  passes it to the preprocessor object.
  
clang.cpp: DriverPreprocessorFactory now calls "InitializePreprocessor" instead of this being done in main().

html::HighlightMacros() now takes a PreprocessorFactory, allowing it to conjure up a new
Preprocessor to highlight macros.

class HTMLDiagnostics now takes a PreprocessorFactory* that it can use for html::HighlightMacros().
Updated clients of HTMLDiagnostics to use this new interface.

Fariborz Jahanian 8e36cddde0 Added property decl support for protocols.
Added assertion if unexpected property decls are found where they don't belong.
Consolidated property decl. printing by using a helper function.

Fariborz Jahanian 9d981eb9ae This patch adds support for declaraing properties in categories,

Ted Kremenek f2e6fcf3bf Hook up HTMLDiagnostics to use Chris's new syntax highlighting. --html-diags
currently doesn't pass in the Preprocessor from the driver, so we don't get
syntax highlighting when we create HTMLDiagnostics in that way.

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.

llvm-svn: 48036

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.

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.

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.

llvm-svn: 46792
2008-02-06 02:01:47 +00:00
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.
