2011-10-06[static analyzer] Fix crash in LiveVariables and Environment::getSVal() when ↵Ted Kremenek
analyzing C++ pointer-to-member calls. Fixes <rdar://problem/10243398>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141312 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-06[analyzer] Remove the dependency on CheckerContext::getStmt() as well as the ↵Anna Zaks
method itself. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141262 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-05[analyzer] OSAtomicChecker implements evalCall in a very invasive way - it ↵Anna Zaks
essentially simulates inlining of compareAndSwap() by means of setting the NodeBuilder flags and calling ExprEngine directly. This commit introduces a new callback just for this checker to unblock checker API cleanup. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141246 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-02Fix LiveVariables analysis bug with MaterializeTemporaryExpr and fix ↵Ted Kremenek
handling in ExprEngine. Fixes <rdar://problem/10201666>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140956 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-01Address PR10616. The crash has already been fixed by Ted in r140725, so just ↵Anna Zaks
refactor to use existing API + test case. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140932 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-30Fix crash when analyzing C++ code involving constant enums and switch ↵Ted Kremenek
statements (<rdar://problem/10202899>). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140844 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-30[analyzer] Add -analyzer-purge option which can take on multiple values, ↵Anna Zaks
remove -analyzer-purge=none. (Small refactor as well: move the work of constructing AnalysisManager from the callers to the class itself.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140838 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-23Removing a bunch of dead returns/breaks after llvm_unreachables.David Blaikie
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140407 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-23Move immutable map canonization out of the removeDeadBindings loop (via ↵Anna Zaks
using ImmutableMapRef). Gives ~2% speedup. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140403 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-22ST->scanReachableSymbols() is creating a SubRegionMap (SRM) on every call ↵Anna Zaks
since one SRM is created in each ScanReachableSymbols instance. Creating the object just once and calling only scan inside the loop gives ~ 14% speed up of the StaticAnalyzer run (Release+Asserts). Pull out the declaration of the ScanReachableSymbols so that it can be used directly. Document ProgramState::scanReachableSymbols() methods. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140323 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-21[analyzer] Fix a bug where PathDiagnosticLocation did not generate a valid ↵Anna Zaks
range and add asserts to check validity of locations early on. Ignore invalid ranges in PathDiagnosticPiece (they could be added by checker writers). Addresses radar://10124836 and radar://radar10102244. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140218 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-20[analyzer] Refactor PathDiagnosticLocation: Remove SourceRange member from ↵Anna Zaks
PathDiagnosticLocation - FullSourceLoc Loc and PathDiagnosticRange Range are sufficient. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140206 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-20[analyzer] Remove dead code. (This code is trying to implement the idea that ↵Anna Zaks
PathDiagnosticClient could implement DiagnosticClient and has been dead for a while). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140198 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-20[analyzer] Refactor PathDiagnosticLocation: Make ↵Anna Zaks
PathDiagnosticLocation(SourceLocation...) private. Most of the effort here goes to making BugReport refer to a PathDiagnosticLocation instead of FullSourceLocation. (Another step closer to the goal of having Diagnostics which can recover from invalid SourceLocations.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140182 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-20[analyzer] Refactor PathDiagnosticLocation: Use the pre-computed Range and ↵Anna Zaks
Location for profile. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140180 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-20[analyzer] Refactor PathDiagnosticLocation: Use PointerUnion of ↵Anna Zaks
LocationContext and AnalysisContext to support creation of PathDiagnosticLocations for checkers which no context sensitivity. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140162 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-20[analyzer] Refactor PathDiagnosticLocation: Lazily query LocationContext for ↵Anna Zaks
a ParentMap as needed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140147 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-20[analyzer] Remove LocationContext and a dependency from PathDiagnosticLoaction.Anna Zaks
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140146 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-20[analyzer] Refactor PathDiagnosticLocation: Pre-compute Range and Location ↵Anna Zaks
with gen methods on object creation instead of computing on demand. This would allow to remove dependency on the other members which help with construction and might not even be valid at later stages (to be removed later on). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140131 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-19Rename SourceLocation::getFileLocWithOffset -> getLocWithOffset.Argyrios Kyrtzidis
It already works (and is useful with) macro locs as well. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140057 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-16[analyzer] Refactor: make PathDiagnosticLocation responsible for validation ↵Anna Zaks
of SourceLocations (commit 5 of ?): - Get rid of PathDiagnosticLocation(SourceRange r,..) constructor by providing a bunch of create methods. - The PathDiagnosticLocation(SourceLocation L,..), which is used by crate methods, will eventually become private. - Test difference is in the case when the report starts at the beginning of the function. We used to represent that point as a range of the very first token in the first statement. Now, it's just a single location representing the first character of the first statement. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139932 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-15[analyzer] Refactor: make PathDiagnosticLocation responsible for validation ↵Anna Zaks
of SourceLocations (commit 4 of ?): - The closing brace is always a single location, not a range. - The test case previously had a location key 57:1 followed by a range [57:1 - 57:1]. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139832 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-15[analyzer] Refactor: make PathDiagnosticLocation responsible for validation ↵Anna Zaks
of SourceLocations (commit 2 of ?): - Fix a fixme and move the logic of creating a PathDiagnosticLocation corresponding to a ProgramPoint into a PathDiagnosticLocation constructor. - Rename PathDiagnosticLocation::create to differentiate from the added constructor. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139825 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-15[analyzer] Refactor: make PathDiagnosticLocation responsible for validation ↵Anna Zaks
of SourceLocations (commit 2 of ?): - Modify all PathDiagnosticLocation constructors that take Stmt to also requre LocationContext. - Add a constructor which should be used in case there is no valid statement/location (it will grab the location of the enclosing function). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139763 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-14[analyzer] After CFG has been linearized, we can have a situation where an ↵Anna Zaks
ExpoledNode has an invalid SourceLocation (which has no correspondence in the source code). This commit is the first step to solve this problem. - It adds LocationContext to the PathDiagnosticLocation object and uses it to lookup the enclosing statement with a valid location. - So far, the LocationContext is only available when the object is constructed from the ExplodedNode. - Already found some subtle bugs(in plist-output-alternate.m) where the intermediate diagnostic steps were not previously shown. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139703 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-14[analyzer] Refactor: Make PathDiagnosticLocation responsible for creating a ↵Anna Zaks
valid object given an ExploadedNode (the same logic can be reused by other checkers). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139672 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-12[analyzer] Fix a new failure encountered while building Adium exposed as a ↵Anna Zaks
result of r138196(radar://10087620). ObjectiveC property of type int has a value of type ObjCPropRef, which is a Loc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139507 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-10Rename the ARC cast kinds to start with "ARC".John McCall
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139466 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-10When converting a block pointer to an Objective-C pointer type, extendJohn McCall
the lifetime of the block by copying it to the heap, or else we'll get a dangling reference because the code working with the non-block-typed object will not know it needs to copy. There is some danger here, e.g. with assigning a block literal to an unsafe variable, but, well, it's an unsafe variable. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139451 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-09Give conversions of block pointers to ObjC pointers a different cast kindJohn McCall
than conversions of C pointers to ObjC pointers. In order to ensure that we've caught every case, add asserts to CastExpr that strictly determine which cast kind is used for which kind of bit cast. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139352 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-02[analyzer] Remove TransferFuncs.h, then deal with the fallout.Jordy Rose
And with that, TransferFuncs is gone! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139003 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-02[analyzer] Move RetainReleaseChecker to the Checkers library and rename it ↵Jordy Rose
to RetainCountChecker...and clean up the file while I'm at it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139002 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-02[analyzer] Remove lingering CFRefCount creation, which would have resulted ↵Jordy Rose
in a leak. There's room for improvement here... git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139000 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-02[analyzer] Move the knowledge of whether or not GC is enabled for the ↵Jordy Rose
current analysis from CFRefCount to ExprEngine. Remove TransferFuncs from ExprEngine and AnalysisConsumer. Demote RetainReleaseChecker to a regular checker, and give it the name osx.cocoa.RetainCount (class name change coming shortly). Update tests accordingly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138998 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-28[analyzer] Introduce a new callback for checkers, printState, to be used for ↵Jordy Rose
debug-printing the contents of a ProgramState. Unlike the other callbacks, this one is a simple virtual method, since it is only to be used for debugging. This new callback replaces the old ProgramState::Printer interface, and allows us to move the printing of refcount bindings from CFRefCount to RetainReleaseChecker. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138728 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-28[analyzer] Remove the ProgramState argument from ExprEngine::evalBind; we ↵Jordy Rose
were ignoring it anyway. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138720 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-28[analyzer] Migrate argument invalidation from CFRefCount to ExprEngine.Jordy Rose
This is a common path for function and C++ method calls, Objective-C messages and property accesses, and C++ construct-exprs. As support, add message receiver accessors to ObjCMessage and CallOrObjCMessage. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138718 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-27[analyzer] Change the check::RegionChanges callback to include the regions ↵Jordy Rose
explicitly requested for invalidation. Also, allow CallOrObjCMessage to wrap a CXXConstructExpr as well. Finally, this allows us to remove the clunky whitelisting system from CFRefCount/RetainReleaseChecker. Slight regression due to CXXNewExprs not yet being handled in post-statement callbacks (PR forthcoming). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138716 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-27[analyzer] Rename current PathDiagnosticClient::HandlePathDiagnostic() to ↵Ted Kremenek
