Ted Kremenek ae01dc73af API cleanup: move more methods from GRStateManager to GRState. 
llvm-svn: 73968
 2009-06-23 17:55:07 +00:00
Ted Kremenek 095f1a9848 Move clients over from using GRStateManager::BindXXX and friends to 
GRState->bindXXX and friends (and constify some arguments along the way).

Ted Kremenek 73777059f0 BugReporter (extensive diagnostics): Do not include the range of target '}' 
llvm-svn: 71832
 2009-05-15 02:46:13 +00:00
Ted Kremenek cfe7d02b2c BugReporter (extensive diagnostics): Add control-flow piece to '}' in 
loop body when generating 'Looping back to the head of the loop'
diagnostics.

llvm-svn: 71829
 2009-05-15 01:50:15 +00:00
Ted Kremenek 5fb7847fbf BugReport::getEndPath() - Only add a Stmt's range to the constructed PathDiagnosticEventPiece if the BugReport contained no explicit ranges. 
llvm-svn: 71516
 2009-05-11 23:50:59 +00:00
Ted Kremenek 2ee73b86c0 EdgeBuilder: DeclStmts and BinaryOperators are not the enclosing location context when they are used as initialization code for loops. 
llvm-svn: 71480
 2009-05-11 22:19:32 +00:00
Ted Kremenek c0b879b4a7 EdgeBuilder::cleanUpLocation() should used the PathDiagnosticLocation constructor for a single point, not a range. 
llvm-svn: 71477
 2009-05-11 21:42:34 +00:00
Ted Kremenek c14b594b14 BugReporter (extensive diagnostics): Add EdgeBuilder::cleanUpLocation for canonicalization locations and use this in both popLocation and rawAddEdge. 
llvm-svn: 71470
 2009-05-11 19:50:47 +00:00
Ted Kremenek 3978f7972d analyzer: 
- Improve -autorelease diagnostics.
- Improve VLA diagnostics.
- Use "short description" for bug when outputting to TextDiagnostics

llvm-svn: 71383
 2009-05-10 05:11:21 +00:00
Ted Kremenek 9abe474852 Add preliminary support for enhancing null-pointer dereference diagnostics. 
llvm-svn: 71135
 2009-05-07 00:45:33 +00:00
Ted Kremenek bb8d546208 Refactor BugReporter interface to have a new 'BugReporterContext' and 
'BugReporterVisitor'. This simplifies callbacks from BugReporter to BugReports
(via VisitNode). It also lays the foundation for arbitrary visitor "call backs"
that can be registered to a BugReporterContext as a PathDiagnostic is
constructed. These call backs can help operate as separate "experts" that can
work on constructed pieces of a PathDiagnostic for which they possess special
knowledge.

 2009-05-06 21:39:49 +00:00
Ted Kremenek a8106efce9 BugReporter (extensive diagnostics): improve location context generation for the 
start of 'do' and '@synchronized' statements.

llvm-svn: 71038
 2009-05-05 23:13:38 +00:00
Ted Kremenek 98017051ae BugReporter (extensive diagnostics): Fix getEnclosingStmtLocation to reason 
about Exprs that are not consumed and fix where the loop iteration diagnostic
goes.

llvm-svn: 71027
 2009-05-05 22:19:17 +00:00
Ted Kremenek e396f72ec7 BugReporter (extensive diagnostics): don't mark location contexts that are 
control-flow expressions as dead.

llvm-svn: 70887
 2009-05-04 18:15:17 +00:00
Ted Kremenek afbff15e64 BugReporter (extensive diagnostics): introduce the notion of a "dead" 
location context.  This allows us to postpone the decision of whether
or not a context should add a control-flow piece to the diagnostics
when inspecting its subexpressions.

llvm-svn: 70545
 2009-05-01 16:08:09 +00:00
Ted Kremenek 29d0880e50 Remove #if 0'ed code. 
llvm-svn: 70542
 2009-05-01 15:19:33 +00:00
Ted Kremenek 9f08b842e1 Fix null dereference. 
llvm-svn: 70417
 2009-04-29 22:05:03 +00:00
Ted Kremenek 47187c6ad2 BugReporter/PathDiagnostics: 
- Add an (optional) short description for BugReports for clients that want
  to distinguish between long and short descriptions for bugs
- Make the bug report for VLA less obscene for Plist diagnostics by using
  the short description

llvm-svn: 70415
 2009-04-29 21:58:13 +00:00
Ted Kremenek 9bea0dc178 Extensive diagnostics: Do not add a location context for do...while statements. 
llvm-svn: 70286
 2009-04-28 04:28:12 +00:00
Ted Kremenek 61114bc558 BugReporter (extensive diagnostics): Clean up do...while control-flow edges, and 
add "Looping back to the head of the loop" diagnostic for loops.

llvm-svn: 70285
 2009-04-28 04:23:15 +00:00
Sebastian Redl a7b98a772c Implement function-try-blocks. However, there's a very subtle bug that I can't track down. 
llvm-svn: 70155
 2009-04-26 20:35:05 +00:00
Eli Friedman 5cdb8cc267 Minor code cleanup. 
llvm-svn: 70144
 2009-04-26 19:04:51 +00:00
Chris Lattner f0b64d73a8 split ObjC and C++ Statements out into their own headers. 
llvm-svn: 70105
 2009-04-26 01:32:48 +00:00
Ted Kremenek 3ebc5057ac BugReporter (extensive diagnostics): Recursively adjust the referred expression 
when popping location contexts.

llvm-svn: 69898
 2009-04-23 16:44:22 +00:00
Ted Kremenek e60809c31d BugReporter (extensive diagnostics): Ignore parentheses when added control-flow 
pieces for location contexts.

llvm-svn: 69895
 2009-04-23 16:19:29 +00:00
Ted Kremenek 48b7875e55 BugReporter (extensive diagnostics): Use correct location for location contexts. 
llvm-svn: 69824
 2009-04-22 20:51:59 +00:00
Ted Kremenek fb05406cef BugReporter (extensive diagnostics): always add an edge if there is no location 
context.

llvm-svn: 69823
 2009-04-22 20:36:26 +00:00
Ted Kremenek 6c867a1460 BugReporter (extensive diagnostics): 
- Remove stale assertion that was breaking the test suite.
- When popping location contexts, only add a control-flow piece for fileID
  locations.

llvm-svn: 69814
 2009-04-22 18:37:42 +00:00
Ted Kremenek 0752a5dff3 BugReporter (extensive diagnostic algorithm): The initial control-flow edge now 
starts from the first character of the first statement.

Douglas Gregor e3dcb2ddd1 FunctionDecl::getBody() is getting an ASTContext argument for use in 
lazy PCH deserialization. Propagate that argument wherever it needs to
be. No functionality change, except that I've tightened up a few PCH
tests in preparation.

Ted Kremenek 86d52c4c02 PathDiagnostic generation: experiment with avoiding generation of control-flow 
pieces between block entrance and block end unless necessary.

llvm-svn: 68483
 2009-04-07 01:34:17 +00:00
Ted Kremenek d7c1aaa6c5 Don't overguard to adding a control-flow piece when "alwaysAdd" is true. 
llvm-svn: 68476
 2009-04-07 00:11:40 +00:00
Ted Kremenek c4c9ed0f9b Rewrite control-flow diagnostic generation "extensive" algorithm using "edge 
contexts".  This allows us to use a stack of contexts to keep track of what control-flow pieces to include when exiting blocks like 'if', 'for', etc.

llvm-svn: 68473
 2009-04-06 23:06:54 +00:00
Ted Kremenek a2a735e7fa Add another null pointer check. Simplify condition. 
llvm-svn: 68283
 2009-04-02 03:44:00 +00:00
Ted Kremenek 5d6d7d8184 Add null pointer check. 
llvm-svn: 68281
 2009-04-02 03:30:55 +00:00
Ted Kremenek afb066d1f5 BugReporter, extensive path-diagnostics: add an extra control-flow edge to the 
enclosing statement when jumping to a subexpression.

llvm-svn: 68244
 2009-04-01 21:12:06 +00:00
Ted Kremenek 95af35e251 Fix comment. 
llvm-svn: 68236
 2009-04-01 19:43:28 +00:00
Ted Kremenek ed47d79cc2 BugReporter: for extensive path diagnostics: 
- When processing BlockEdges with terminators, using the condition as the
  control-flow point for terminators that are expressions (e.g., '&&', '?')
- When processing events, allow intra-compound statement "jumping"

llvm-svn: 68228
 2009-04-01 18:48:52 +00:00
Ted Kremenek 9ce13241ff BugReporter: for extensive PathDiagnostic generation, add control-flow from the 
start of the function/method.

llvm-svn: 68217
 2009-04-01 17:52:26 +00:00
Ted Kremenek 45a75f718c BugReporter: For the "extensive" PathDiagnostic generation algorithm, elide most 
intra-compound statement jumps unless they are between terminators (i.e.,
branches).

llvm-svn: 68216
 2009-04-01 17:18:21 +00:00
Ted Kremenek 0bb0909233 - Changed PathDiagnosticPiece::getLocation() to return a PathDiagnosticLocation 
instead of a FullSourceLoc. This resulted in a bunch of small edits in various
  clients.
- Updated BugReporter to include an alternate PathDiagnostic generation
  algorithm for PathDiagnosticClients desiring more control-flow pieces.

llvm-svn: 68193
 2009-04-01 06:13:56 +00:00
Ted Kremenek 7062c50772 More code reshuffling. No functionality change. 
llvm-svn: 68157
 2009-03-31 23:00:32 +00:00
Ted Kremenek 4e81c3ccac Allow two codepaths for PathDiagnostic generation. This patch mainly consists of 
refactoring to make this possible (no functionality change).

llvm-svn: 68141
 2009-03-31 20:22:36 +00:00
Ted Kremenek ac508988a5 Simplify more code by using SVal::getAsSymbol(). 
llvm-svn: 68052
 2009-03-30 19:53:37 +00:00
Ted Kremenek a53eb7fa80 Convert use of loc::SymbolVal and nonloc::SymbolVal to V.getAsSymbol(). This 
also makes this code more correct as it transparently handles SVals that wrapped
TypedViewRegions(SymbolicRegions).

llvm-svn: 68048
 2009-03-30 18:39:15 +00:00
Ted Kremenek b505811250 Adjust control-flow endpoints for '&&' and '||'.

Ted Kremenek cd58cced81 Text PathDiagnosticBuilder::getEnclosingStmt() about '?' 
llvm-svn: 67909
 2009-03-28 04:08:14 +00:00
Ted Kremenek b9411565ea Teach PathDiagnosticBuilder::getEnclosingStmtLocation() about while/if/do/for, 
etc., so that the "body" is always considered a top-level statement for edge
transitions (even if it is an expression).
