TranslationUnit object instead of an ASTContext. By default it calls
Initialize(ASTConstext& Context) (to match with the current interface used by
most ASTConsumers).
Modified the ObjC-Rewriter to use InitializeTU, and to tell the TranslationUnit
to not free its Decls. This is a workaround for: <rdar://problem/5966749>
llvm-svn: 51825
essentially that we were destroying the declarations twice.
(Note that we don't use -serialize directly in the testsuite, only
SerializeTest.)
llvm-svn: 51768
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.
llvm-svn: 50149
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.
llvm-svn: 49875
Added assertion if unexpected property decls are found where they don't belong.
Consolidated property decl. printing by using a helper function.
llvm-svn: 49862
currently doesn't pass in the Preprocessor from the driver, so we don't get
syntax highlighting when we create HTMLDiagnostics in that way.
llvm-svn: 49796
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.
llvm-svn: 48989
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
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
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
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
--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
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.
llvm-svn: 46791
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.
llvm-svn: 46490
Refactoring: for GREngine and GRConstants, pushed references to CFG, ASTContext,
and the top-level FunctionDecl into ExplodedGraphImpl.
llvm-svn: 46475
Created include/clang/Analysis/Analyses directory.
- Moved LiveVariables.h and UninitializedValues.h into this dir.
Moved ExprDeclBitVector.h into Analysis/Support.
Updated all clients who use these headers to reflect the new paths.
llvm-svn: 45292
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
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
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
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
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.
llvm-svn: 45004
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.
llvm-svn: 44878
a bug where the statement pretty-printer used iostreams but the AST printer
did not. This was an issue when dumping ASTs to something other than stderr.
Updated SerializationTest to use the new iostreams interface for the AST printer.
llvm-svn: 44417
which is now used (or subclasssed) by the ASTConsumers. This new class
stores a FILE* that is used for writing, instead of just hardwiring output
to stderr (it defaults to stderr if no FILE* is provided).
Modified CreateASTPrinter() to accept a FILE* for printing.
llvm-svn: 44377
- Add Sema::CurMethodDecl, in preparation for adding ObjcIvarRefExpr.
- Add ObjcInterfaceDecl::lookupInstanceVariable(), in prep for adding ivars.
- A couple renames in ObjcInterfaceDecl, while I was in the vicinity:-)
llvm-svn: 44015
Make target info available to clang code generator. This is far from complete but this helps clang codegen module make progress.
At the moment target triplet and target description strings are hard coded in clang::TargetInfo
