Argyrios Kyrtzidis 2797df6a24 Amend r138129 (reduction of SLocEntries) which introduced performance regression due
to increased calls to SourceManager::getFileID. (rdar://9992664)

Use a slightly different approach that is more efficient both in terms of speed
(no extra getFileID calls) and in SLocEntries reduction.

Comparing pre-r138129 and this patch we get:

For compiling SemaExpr.cpp reduction of SLocEntries by 26%.
For the boost enum library:
  -SLocEntries -34% (note that this was -5% for r138129)
  -Memory consumption -50%
  -PCH size -31%

Reduced SLocEntries also benefit the hot function SourceManager::getFileID,
evident by the reduced "FileID scans".

Ted Kremenek ee9848e20d Fix regression in -Wuninitialized involving VLAs. It turns out that we were modeling sizeof(VLAs)
incorrectly in the CFG, and also the static analyzer.  This patch regresses the analyzer a bit, but
that needs to be followed up with a better solution.

Caitlin Sadowski afbbd8e5ad Thread-safety analysis: adding in a basic lockset tracking system. This
system flags an error when unlocking a lock which was not held, locking
the same lock twice, having a different lockset on each iteration of a
loop, or going out of scope while still holding a lock. In order to
successfully use the lockset, this patch also makes sure that attribute
arguments are attached correctly for later parsing.

This patch was also worked on by DeLesley Hutchins.

Note: This patch has been reviewed by Chandler Carruth and Jeffrey
Yasskin. Feel free to provide post-commit review comments for a
subsequent patch.

Chandler Carruth 41c6dcc734 Fix a crash-on-valid that has been here for a very long time:
const int &x = x;

This crashed by inifinetly recursing within the lvalue evaluation
routine. I've added a (somewhat) braindead way of preventing this
recursion. If folks have better suggestions for how to avoid it I'm all
ears.

That said, we have some work to do. This doesn't trigger a single
warning for uninitialized, self-initialized or otherwise completely
wrong code. In some senses, the crash was almost better.

Argyrios Kyrtzidis 61ef3db222 Boost the efficiency of SourceManager::getMacroArgExpandedLocation.
Currently getMacroArgExpandedLocation is very inefficient and for the case
of a location pointing at the main file it will end up checking almost all of
the SLocEntries. Make it faster:

-Use a map of macro argument chunks to their expanded source location. The map
 is for a single source file, it's stored in the file's ContentCache and lazily
 computed, like the source lines cache.
-In SLocEntry's FileInfo add an 'unsigned NumCreatedFIDs' field that keeps track
 of the number of FileIDs (files and macros) that were created during preprocessing
 of that particular file SLocEntry. This is useful when computing the macro argument
 map in skipping included files while scanning for macro arg FileIDs that lexed from
 a specific source file. Due to padding, the new field does not increase the size
 of SLocEntry.

Chandler Carruth 4e6bd3955f Remove this test. It requires C++ standard library headers, which we'd
like to avoid within the Clang test suite, it doesn't verify the output
at all so it only servers as a test that Clang doesn't crash, and
finally all it does is declare a function that returns a vector and call
it. Probably the biggest thing being tested here is Clang's parsing of
the vector template, and we have lots of good template parsing tests. We
don't need another in codegen.

Douglas Gregor ab443b9da5 Introduce a module visitation function that starts at the top-level
modules (those that no other module depends on) and performs a search
over all of the modules, visiting a new module only when all of the
modules that depend on it have already been visited. The visitor can
abort the search for all modules that a module depends on, which
allows us to minimize the number of lookups necessary when performing
a search.

Switch identifier lookup from a linear walk over the set of modules to
this module visitation operation. The behavior is the same for simple
PCH and chained PCH, but provides the proper search order for
modules. Verified with printf debugging, since we don't have enough in
place to actually test this.

Argyrios Kyrtzidis eeca36fe9a For assigning SourceLocations to macro arg tokens, reserve a single SLocEntry
for tokens that are lexed consecutively from the same FileID, instead of creating
a SLocEntry for each token. e.g for

   assert(foo == bar);

there will be a single SLocEntry for the "foo == bar" chunk and locations
for the 'foo', '==', 'bar' tokens will point inside that chunk.

For parsing SemaExpr.cpp, this reduced the number of SLocEntries by 25%.

Anna Zaks f86615ca5c Static Analyzer Diagnostics: Kill the addVisitorCreator(callbackTy, void*) API in favor of addVisitor(BugReporterVisitor*).
1) Create a header file to expose the predefined visitors. And move the parent(BugReporterVisitor) there as well.

2) Remove the registerXXXVisitor functions - the Visitor constructors/getters can be used now to create the object. One exception is registerVarDeclsLastStore(), which registers more then one visitor, so make it static member of FindLastStoreBRVisitor.

3) Modify all the checkers to use the new API.

Douglas Gregor 4dd3e948ef Teach ModuleManager::addModule() to check whether a particular module
has already been loaded before allocating a new Module structure. If
the module has already been loaded (uniquing based on file name), then
just return the existing module rather than trying to load it again.

This allows us to load a DAG of modules. Introduce a simple test case
that forms a diamond-shaped module graph, and illustrates that a
source file importing the bottom of the diamond can see declarations
in all four of the modules that make up the diamond.

Note that this version moves the file-opening logic into the module
manager, rather than splitting it between the module manager and the
AST reader. More importantly, it properly handles the
weird-but-possibly-useful case of loading an AST file from "-".

Douglas Gregor df0c151ba6 Keep track of which modules have been loaded directly (e.g., via
-import-module) vs. loaded because some other module depends on
them. As part of doing this, pass down the module that caused a module
to be loaded directly, rather than assuming that we're loading a
chain. Finally, write out all of the directly-loaded modules when
serializing an AST file (using the new IMPORTS record), so that an AST
file can depend on more than one other AST file, all of which will be
loaded when that AST file is loaded. This allows us to form and load a
tree of modules, but we can't yet load a DAG of modules.

Chad Rosier bc5ea3d4b9 [driver] Clang doesn't support -mkernel/-fapple-kext for i386, so it's
automatically invoking llvm-gcc's cc1plus, which doesn't support all options
supported by Clang.  Therefore, filter out unsupported options.

Chandler Carruth 463394752b Whitelist operator== and operator!= as valid for unused value warnings,
even when overloaded and user-defined. These operators are both more
valuable to warn on (due to likely typos) and extremely unlikely to be
reasonable for use to trigger side-effects.

llvm-svn: 137823
2011-08-17 09:49:44 +00:00
Chandler Carruth e2669397f1 Treating the unused equality comparisons as something other than part of
-Wunused was a mistake. It resulted in duplicate warnings and lots of
other hacks. Instead, this should be a special sub-category to
-Wunused-value, much like -Wunused-result is.

Moved to -Wunused-comparison, moved the implementation to piggy back on
the -Wunused-value implementation instead of rolling its own, different
mechanism for catching all of the "interesting" statements.

I like the unused-value mechanism for this better, but its currently
missing several top-level statements. For now, I've FIXME-ed out those
test cases. I'll enhance the generic infrastructure to catch these
statements in a subsequent patch.

This patch also removes the cast-to-void fixit hint. This hint isn't
available on any of the other -Wunused-value diagnostics, and if we want
it to be, we should add it generically rather than in one specific case.

Chandler Carruth e89ca5f7d2 Don't suggest assignment in implausible situation. We still warn, as the
code is very likely to be buggy, but its going to require more
significant changes on the part of the user to correct it in this case.

llvm-svn: 137820
2011-08-17 08:38:11 +00:00
Chandler Carruth ae51ecc57b Introduce a new warning, -Wtop-level-comparison. This warning is
a complement to the warnings we provide in condition expressions. Much
like we warn on conditions such as:

  int x, y;
  ...
  if (x = y) ... // Almost always a typo of '=='

This warning applies the complementary logic to "top-level" statements,
or statements whose value is not consumed or used in some way:

  int x, y;
  ...
  x == y; // Almost always a type for '='

We also mirror the '!=' vs. '|=' logic.

The warning is designed to fire even for overloaded operators for two reasons:

1) Especially in the presence of widespread templates that assume
   operator== and operator!= perform the expected comparison operations,
   it seems unreasonable to suppress warnings on the offchance that
   a user has written a class that abuses these operators, embedding
   side-effects or other magic within them.
2) There is a trivial source modification to silence the warning for
   truly exceptional cases:

     (void)(x == y); // No warning

A (greatly reduced) form of this warning has already caught a number of
bugs in our codebase, so there is precedent for it actually firing. That
said, its currently off by default, but enabled under -Wall.

There are several fixmes left here that I'm working on in follow-up
patches, including de-duplicating warnings from -Wunused, sharing code
with -Wunused's implementation (and creating a nice place to hook
diagnostics on "top-level" statements), and handling cases where a proxy
object with a bool conversion is returned, hiding the operation in the
cleanup AST nodes.

Suggestions for any of this code more than welcome. Also, I'd really
love suggestions for better naming than "top-level".

be at the first expansion of the argument.
 e.g.

where 'foo' was expanded into.

Francois Pichet 00c7e6ceb1 Implement function template specialization at class scope extension in Microsoft mode. A new AST node is introduced: ClassScopeFunctionSpecialization. This node holds a FunctionDecl that is not yet specialized; then during the class template instantiation the ClassScopeFunctionSpecialization will spawn the actual function specialization.
Example:
template <class T>
class A {
public:
  template <class U> void f(U p) {  }
  template <> void f(int p) {  } // <== class scope specialization
};

This extension is necessary to parse MSVC standard C++ headers, MFC and ATL code.
BTW, with this feature in, clang can parse (-fsyntax-only) all the MSVC 2010 standard header files without any error.

Ted Kremenek e8f7316fee [analyzer] change "tag" in ProgramPoint from "void*" to a ProgramPointTag*.
Having a notion of an actual ProgramPointTag will aid in introspection of the analyzer's behavior.
For example, the GraphViz output of the analyzer will pretty-print the tags in a useful manner.

Anna Zaks fdd0aca0a5 MacOSKeychainAPIChecker:
Report errors earlier: on checkDeadSymbols() and clear the state after the symbol we are tracking goes out of scope. 

Also, perform lazy error checking. Instead of forcing the paths to be split depending one the return value of the allocator, make the return symbol depend on the allocated data symbol, which prolongs its life span to the time when the allocated data symbol becomes dead.

Anna Zaks c94894fbc2 MacOSKeychainAPIChecker: There is no need to use SymbolMetadata to represent the allocated data symbol, we can just use the symbol corresponding to the SymbolicRegion. This simplifies tracking of the symbol, for example, SymbolMetadata needs to go through extra hoops to stay alive.
Make AllocationState internal to the MacOSKeychainAPIChecker class.

Douglas Gregor dab42432d7 In the serialized AST format, make the translation unit a "predefined"
declaration that never actually gets serialized. Instead, serialize
the various kinds of update records (lexical decls, visible decls, the
addition of an anonymous namespace) for the translation unit, even if
we're not chaining. This way, we won't have to deal with multiple
loaded translation unit declarations.
