Still to do:
- Chris will fix a bug in the rewriting engine for nested stmts. For example, the following:
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
tranlates to:
NSAutoreleasePool * pool = objc_msgSend(objc_msgSend(objc_getClass("NSAutoreleasePool"), sel_getUid("alloc")), sel_getUid("init"))utoreleasePool"), sel_getUid("alloc")) init];
...which is correct, except there is garbage after sel_getUid("init"). This is because the rewriter isn't updating the extent of the containing message expression.
- Do the crazy cast thang.

protocol meta-data (unlike what documentation says). 2) Include objc.h so,
we can compile the generated metadata with both gcc and clang.
llvm-svn: 43311
new split-header file configuration (Serialize.h and Deserialize.h)
now in place in the core LLVM repository.
Removed unneeded SerializeTrait specializations for enums in
TokenKinds.h
llvm-svn: 43306
we currently turn:
c = @encode(char *)[2] + 4;
into:
c = "foo"[2] + 4;
Right now the foo string is hard coded, but you can imagine a world
where it wouldn't be :)
llvm-svn: 43093
Silenced some VC++ warnings.
Had to rephrase a partial specialization of the IntrospectionTrait struct in SerializationTest.cpp, please review.
Added a compiler specific workaround in IdentifierTable.h. Is that the way to fix this kind of issues?
llvm-svn: 43074
serialization logic as well as driver code is now in
Driver/SerializationTest.cpp. The status of this code is that it
should be used by no clients.
Added --test-pickling option to driver to run the serialization code.
Modified IdentifierInfo and IdentifierTable to have friend classes
that permit object serialization. Such friendship may not be needed
in the final design.
llvm-svn: 43052
Rename SourceRange::Begin()/End() to getBegin()/getEnd() for
consistency with other code.
Start building the rewriter towards handling @encode.
llvm-svn: 43047
predefined macros. Previously, these were handled by the driver,
now they are handled by the preprocessor.
Some fallout of this:
1. Instead of preprocessing two buffers (the predefines, then the
main source file) we now start preprocessing the main source
file and inject the predefines as a "psuedo #include" from the
main source file.
2. #1 allows us to nuke the Lexer::IsMainFile flag and simplify
Preprocessor::isInPrimaryFile.
3. The driver doesn't have to know about standard #defines, the
preprocessor knows, which is nice for people wanting to define
their own drivers.
4. This allows us to put normal tokens in the predefine buffer,
for example a definition for __builtin_va_list that is
target-specific, and a typedef for id in objc.

using "-parse-ast -verify".
Updated all test cases (using a sed script) that invoked -parse-ast-check to
now use -parse-ast -verify.
Fixed a bug where using "-verify" instead of "-parse-ast-check" would not
correctly create the DiagClient needed to accumulate diagnostics.
llvm-svn: 42365
ASTConsumer can also be verified using the diagnostics checker. From
the command line, users may activate diagnostic checking using the
"-verify" option. For example, "clang -verify -warn-dead-stores"
checks if the warnings flagged by the dead store checker match those
in the comments.
Note that we still have the option "-parse-ast-check" for backwards
comptability with existing test cases. This option is now equivalent to
"-parse-ast -verify".
llvm-svn: 42362
"CheckDiagnostics" (used for -parse-ast-check) to check the
diagnostics of any ASTConsumer.
Reimplemented CheckDiagnostics to use CheckASTConsumer instead.
Added driver option -warn-dead-stores-check, which checks the
diagnostics generated by the DeadStores checker. This is implemented
using CheckASTConsumer.111
llvm-svn: 42310
between forward and backward analyses, with trait classes being used
to implement the key differences in operations/functionality.
Converted the LiveVariables analysis to use the generic DataflowSolver. This,
along with removing some extra functionality that was not needed, reduced
the code for LiveVariables by over half.
Modified Driver code to handle the updated interface to LiveVariables.
Modified the DeadStores checker to handle the update interface to
LiveVariables.
Updated DataflowValues (generic ADT to store dataflow values) to also
store values for blocks. This is used by DeadStores. Updated some comments.
llvm-svn: 42293
"The ExpectedStr search was starting at the end of the comment string.
This patch starts the search at the beginning of the comment string.
After applying this patch, clang -parse-ast-check on negative test
case source files worked as expected."

The previous naming scheme was confusing, since it resulted in both the Parser and Action modules having methods with the same name. In addition, the Action module never does any parsing...
llvm-svn: 41986
Move Identifier/Loc instance variables (and associated getters/setters) down from Decl to ScopedDecl/FieldDecl.
Objc AST's can now inherit from Decl without getting instance variables and types that are C specific. For now, I am keeping NextDeclarator, since I believe it may be useful to ObjC. If not, it can be moved later.
llvm-svn: 41934
void func() {
int xx = xx; // incorrectly diagnosed 'xx' as an undeclared identifier.
}
This smallish bug resulted in a largish fix. Here are some highlights:
- Needed to make sure ParseDeclarator is called *before* parsing any
initializer. Removed the "Init" argument to ParseDeclarator.
- Added AddInitializerToDecl() to the Action & Sema classes.
In Sema, this hook is responsible for validating the initializer and
installing it into the respective decl.
- Moved several semantic checks from ParseDeclarator() to
FinalizeDeclaratorGroup(). Previously, this hook was only responsible for
reversing a list. Now it plays a much larger semantic role.
All of the above changes ended up simplifying ParseDeclarator(), which
is goodness...

that refer to direct function calls.
Modified interface of LiveVariables to only track liveness of VarDecls.
This cleans up a bunch of edge cases, and removed the bug just mentioned.
llvm-svn: 41797
"CFGVisitor", which now handles all the boilerplate for iterating over
the function definitions in a translation unit and building the CFGs.
This logic was previously replicated for each driver option that used
CFGs.
The options -dump-cfg, -view-cfg, -check-dead-stores, and
-dump-live-variables now use this refactored code.
llvm-svn: 41779
to variables that are no longer live. This analysis is built on top
of CFGs and the LiveVariables analysis.
changes to driver:
added driver option "-check-dead-stores" to run the analysis
llvm-svn: 41754
source-level CFGs. This code may change significantly in the near
future as we explore different means to implement dataflow analyses.
Added a driver option, -dump-live-variables, to view the output of
live variable analysis. This output is very ALPHA; it will be improved shortly.
llvm-svn: 41737
(LLVM-provided) graph algorithms such as DFS and graph visualization
to work effortless on source-level CFGs.
Further cleanup on pretty printing of CFGs. CFGBlock::dump and
CFGBlock::print now take the parent CFG as an argument. This allows
CFGBlocks to print their own appropriate label indicating whether or
not they are the Entry/Exit/IndirectGotoBlock without the CFG::print
routine doing it instead.
Added Graphviz visualization for CFGs: CFG::viewCFG. This employs the
GraphTraits just implemented.
Added "-view-cfg" mode the to clang driver. This is identical to
"-dump-cfg" except that it calls Graphviz to visualize the CFGs
instead of dumping them to the terminal.
llvm-svn: 41580
Added explicit "Exit" CFGBlock pointer to the source-level CFG.
Changed the construction of blocks with "return" statements to have the
return statement appear both as a statement in the list of statements for
a CFGBlock as well as appear as a control-flow terminator. Also removed
the implicit linearization of "return" so that the return value and the
return statement did not appear as separate statements in the block.
llvm-svn: 41323
Added builder code to translate ASTs to CFGs. This currently supports
if, return, and non-control flow statements.
Added pretty-printer to debug CFGs.
Added a "-dump-cfg" option to the clang driver to dump CFGs for code
sent through the frontend.
llvm-svn: 41252
preprocessor state, causing bogus diagnostics when the file is parsed for real. This
implements Misc/diag-checker.c. Thanks to Ted for noticing this.
llvm-svn: 41000
the AST in a structural, non-pretty, form useful for understanding
the AST. It isn't quite done yet, but is already somewhat useful.
For this example:
int test(short X, long long Y) {
return X < ((100));
}
we get (with -parse-ast-dump):
int test(short X, long long Y)
(CompoundStmt 0x2905ce0
(ReturnStmt 0x2905cd0
(BinaryOperator 0x2905cb0 '<'
(ImplicitCastExpr 0x2905ca0
(DeclRefExpr 0x2905c20 Decl='X' 0x2905bb0))
(ParenExpr 0x2905c80
(ParenExpr 0x2905c60
(IntegerLiteral 0x2905c40 100))))))
