2012-03-06[analyzer] add a diagnostic event when entering a call via inlining, within ↵Ted Kremenek
the callee, and add an edge. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152086 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-02[analyzer diagnostics] flush locations *before* popping the current path ↵Ted Kremenek
when visiting a CallEnter. Fixes <rdar://problem/10967815> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151938 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-02[analyzer diagnostics] Change CompactPathDiagnostic to recursively compact ↵Ted Kremenek
diagnostics in calls into macro pieces. Also fix handling of macros within calls in the HTMLDiagnostics. This also adds a test case for r151774. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151872 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-01[analyzer] Diagnostics - do not try to cleanup the path with macros, itAnna Zaks
will be done by the general cleanup later on. A Patch by Ted. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151784 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-01Change if...else if...else if... to a switch.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151775 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-28[analyzer diagnostics] start prototyping stripping PathDiagnostics of ↵Ted Kremenek
unnecessary cruft caused by path inlining. This introduces a concept of a "prunable" PathDiagnosticEvent. Currently this is a flag, but we may evolve the concept to make this more dynamically inferred. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151663 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-24Make PathDiagnosticBuilder sensitive to varying LocationContexts, thus ↵Ted Kremenek
fixing a bug in the inlining diagnostics where the wrong location could be used. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151349 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-24Reapply r151317, but when computing the PathDiagnostic profile and size keep ↵Ted Kremenek
into account the nested structure. Also fix a problem with how inlining impacted Plist diagnostics, and adjust some ranges in the Plist output due to richer information. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151346 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-23[analyzer] Malloc: unique leak reports by allocation site.Anna Zaks
When we find two leak reports with the same allocation site, report only one of them. Provide a helper method to BugReporter to facilitate this. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151287 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-20Basic: import IntrusiveRefCntPtr<> into clang namespaceDylan Noblesmith
The class name is long enough without the llvm:: added. Also bring in RefCountedBase and RefCountedBaseVPTR. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150958 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-08Remove explicit delete of PathDiagnosticMacroPiece, as it is now reference ↵Ted Kremenek
counted. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150110 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-08Change PathDiagnosticPieces to be reference counted (simplifying their ↵Ted Kremenek
management), and introduce 'PathPieces' as a common container for PathDiagnosticPieces. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150054 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-07Revert my patches which removed Diagnostic.h includes by moving some ↵Benjamin Kramer
operator overloads out of line. This seems to negatively affect compile time onsome ObjC tests (which use a lot of partial diagnostics I assume). I have to come up with a way to keep them inline without including Diagnostic.h everywhere. Now adding a new diagnostic requires a full rebuild of e.g. the static analyzer which doesn't even use those diagnostics. This reverts commit 6496bd10dc3a6d5e3266348f08b6e35f8184bc99. This reverts commit 7af19b817ba964ac560b50c1ed6183235f699789. This reverts commit fdd15602a42bbe26185978ef1e17019f6d969aa7. This reverts commit 00bd44d5677783527d7517c1ffe45e4d75a0f56f. This reverts commit ef9b60ffed980864a8db26ad30344be429e58ff5. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150006 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149939 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-05Basic: import SmallString<> into clang namespaceDylan Noblesmith
(I was going to fix the TODO about DenseMap too, but that would break self-host right now. See PR11922.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149799 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-04Move a method from IdentifierTable.h out of line and remove the SmallString ↵Benjamin Kramer
include. Fix all the transitive include users. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149783 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-04Move various diagnostic operator<< overloads out of line and remove includes ↵Benjamin Kramer
of Diagnostic.h. Fix all the files that depended on transitive includes of Diagnostic.h. With this patch in place changing a diagnostic no longer requires a full rebuild of the StaticAnalyzer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149781 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-28StaticAnalyzer: Move ObjC- and CXX-specific methods out of line so checkers ↵Benjamin Kramer
that don't care about the language don't have to pull in all the headers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149178 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-26Change references to 'const ProgramState *' to typedef 'ProgramStateRef'.Ted Kremenek
At this point this is largely cosmetic, but it opens the door to replace ProgramStateRef with a smart pointer that more eagerly acts in the role of reclaiming unused ProgramState objects. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149081 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-06[analyzer] Make the entries in 'Environment' context-sensitive by making ↵Ted Kremenek
entries map from (Stmt*,LocationContext*) pairs to SVals instead of Stmt* to SVals. This is needed to support basic IPA via inlining. Without this, we cannot tell if a Stmt* binding is part of the current analysis scope (StackFrameContext) or part of a parent context. This change introduces an uglification of the use of getSVal(), and thus takes two steps forward and one step back. There are also potential performance implications of enlarging the Environment. Both can be addressed going forward by refactoring the APIs and optimizing the internal representation of Environment. This patch mainly introduces the functionality upon when we want to build upon (and clean up). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@147688 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-14Change operator<< for raw_ostream and NamedDecl to take a reference instead ↵Benjamin Kramer
of a pointer. Passing a pointer was a bad idea as it collides with the overload for void*. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141971 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-10Constant expression evaluation refactoring:Richard Smith
- Remodel Expr::EvaluateAsInt to behave like the other EvaluateAs* functions, and add Expr::EvaluateKnownConstInt to capture the current fold-or-assert behaviour. - Factor out evaluation of bitfield bit widths. - Fix a few places which would evaluate an expression twice: once to determine whether it is a constant expression, then again to get the value. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141561 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

2011-09-16[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 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
2011-08-24[analyzer] Allow checker writes to specify that no region should be ↵Anna Zaks
accosiated with the report. (Useful when we report an error on endOfPath or deadSymbols, when the range of the last expression might have nothing to do with the error.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138474 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-22Static Analyzer Diagnostics: Allow checkers to add ExtraDescriptiveText, now ↵Anna Zaks
renamed into ExtraText, to the diagnostic without subclassing BugReport. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138272 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-21[analyzer] Replace calls to getNameAsString() with StringRef equivalents.Jordy Rose
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138215 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-20Static Analyzer Diagnostics: Move the responsibility for generating the ↵Anna Zaks
endOfPath diagnostic piece from BugReport to BugReporterVisitor. Switch CFRefCount to use visitors in order to generate the endOfPath piece. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138184 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-19Static Analyzer Diagnostics: Switch CFRefCount to using the new visitor API. ↵Anna Zaks
BugReport no longer needs to inherit from BugReporterVisitor. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138142 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-19Static Analyzer Diagnostics: Kill the addVisitorCreator(callbackTy, void*) ↵Anna Zaks
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138126 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-19Fix a memory leak in the analyzer - BugReports didn't get freed. Plus, ↵Anna Zaks
remove invalid assert from the destructor which wasn't called previously due to the leak. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138027 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-18Static Analyzer Diagnostics: Move custom diagnostic visitors from ↵Anna Zaks
BugReporterContext to BugReport. One API change: I added BugReporter as an additional parameter to the BugReporterVisitor::VisitNode() method to allow visitors register other visitors with the report on the fly (while processing a node). This functionality is used by NilReceiverVisitor, which registers TrackNullOrUndefValue when the receiver is null. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138001 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-17Remove EnhancedBugReport and RangedBugReport - pull all the extra ↵Anna Zaks
functionality they provided into their parent BugReport. The only functional changes are: made getRanges() non const - it adds default range to Ranges if none are supplied, made getStmt() private, which was another FIXME. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137894 91177308-0d34-0410-b5e6-96231b3b80d8
