2011-10-26[analyzer] Remove EmitBasicReport form CheckerContext.Anna Zaks
The path sensitive checkers should use EmitBasicReport, which provides the node information. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143060 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-26[analyzer] Rename generateNode -> addTransition in CheckerContextAnna Zaks
Also document addTransition methods. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143059 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143058 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-26[analyzer] GenericNodeBuilder -> NodeBuilder.Anna Zaks
Remove GenericNodeBuilder and use a class inherited from NodeBuilder instead. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143057 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-25[analyzer] Remove getEngine() form CheckerContextAnna Zaks
A step toward making sure that diagnostics report should only be generated though the CheckerContext and not though BugReporter or ExprEngine directly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142947 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-25[analyzer] Simplify CheckerContextAnna Zaks
Remove dead members/parameters: ProgramState, respondsToCallback, autoTransition. Remove addTransition method since it's the same as generateNode. Maybe we should rename generateNode to genTransition (since a transition is always automatically generated)? git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142946 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142945 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-25[analyzer] Make branch for condition callback use CheckerContextAnna Zaks
Now, all the path sensitive checkers use CheckerContext! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142944 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-25[analyze] Convert EndOfPath callback to use CheckerContextAnna Zaks
Get rid of the EndOfPathBuilder completely. Use the generic NodeBuilder to generate nodes. Enqueue the end of path frontier explicitly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142943 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-24[analyzer] Node builders cleanup + commentsAnna Zaks
Renamed PureNodeBuilder->StmtNodeBuilder. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142849 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-24[analyzer] Remove the old StmtNodeBuilder.Anna Zaks
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142848 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-24[analyzer] Completely remove the global Builder object.Anna Zaks
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142847 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-24[analyzer] Convert ExprEngine::visit() to use short lived builders.Anna Zaks
This commit removes the major functional dependency on the ExprEngine::Builder member variable. In some cases the code became more verbose. Particularly, we call takeNodes() and addNodes() to move responsibility for the nodes from one builder to another. This will get simplified later on. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142831 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-24[analyzer] Convert VisitDeclStmt to use local node builder.Anna Zaks
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142830 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-24[analyzer] Convert more functions (ex:evalBind()) to iterative buildersAnna Zaks
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142829 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-24[analyzer] Convert VisitUnaryOperator to use short lived Node buildersAnna Zaks
To convert iteratively, we take the nodes the local builder will process from the from the global builder and add the generated nodes after the short lived builder is done. PureStmtNodeBuilder is the one we should eventually use everywhere. Added Stmt index and Builder context as ExprEngine globals. To avoid passing them around. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142828 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-24[analyzer] Use a temporary builder in CheckerContext.Anna Zaks
First step toward removing the global Stmt builder. Added several transitional methods (like takeNodes/addNodes). + Stop early if the set of exploded nodes for the next iteration is empty. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142827 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-24[analyzer] Pass external Dst set to NodeBuilderAnna Zaks
This moves the responsibility for storing the output node set from the builder to the clients. The builder is just responsible for transforming an input set into the output set: {SrcSet/SrcNode} -> {Frontier}. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142826 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-24Rename AnalysisContext to AnalysisDeclContext. Not only is this name more ↵Ted Kremenek
accurate, but it frees up the name AnalysisContext for other uses. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142782 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-23[analyzer] Remove LocationContext creation methods from AnalysisManager, and ↵Ted Kremenek
change clients to use AnalysisContext instead. WIP to remove/reduce ExprEngine's usage of AnalysisManager. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142739 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-18[analyzer] Move predecessor into the NodeBuilder context.Anna Zaks
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142454 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-18[analyzer] Make NodeBuilder and Pred node loosely coupledAnna Zaks
NodeBuilder should not assume it's dealing with a single predecessor. Remove predecessor getters. Modify the BranchNodeBuilder to not be responsible for doing auto-transitions (which depend on a predecessor). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142453 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-18[analyzer] Remove StmtNodeBuilder from CheckerContextAnna Zaks
It now only depends on a generic NodeBuilder instead. As part of this change, make the generic node builder results finalized by default. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142452 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-18[analyzer] Modularize builder use in processBranch.Anna Zaks
Take advantage of the new builders for branch processing. As part of this change pass generic NodeBuilder (instead of BranchNodeBuilder) to the BranchCondition callback and remove the unused methods form BranchBuilder. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142448 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-18[analyzer] Pull Pred out of NodeBuilderContext.Anna Zaks
Each builder will have a different one, so it doesn't make sense to keep it in the context. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142447 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-18[analyzer] NodeBuilder Refactoring: Subclass BranchNodeBuilder from NodeBuilder.Anna Zaks
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142444 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-18[analyzer] Node Builder refactoring: Introduce a simple Node Builder ↵Anna Zaks
responsible for generating the node frontier. Currently we have a bunch of different node builders which provide some common functionality but are difficult to refactor. Each builder generates nodes of different kinds and calculates the frontier nodes, which should be propagated to the next step (after the builder dies). Introduce a new NodeBuilder which provides very basic node generation facilities but takes care of the second problem. The idea is that all the other builders will eventually use it. Use this builder in CheckerContext instead of StmtNodeBuilder (the way the frontier is propagated to the StmtBuilder is a hack and will be removed later on). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142443 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-07Remove AnalysisContext::getLiveVariables(), and introduce a templatized ↵Ted Kremenek
mechanism to lazily create analyses that are attached to AnalysisContext objects. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141425 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-07[analyzer] Previously, we were passing to CheckerContext enough info to ↵Anna Zaks
construct ProgramPoint and it would pass it to NodeBuilder, which in turn would construct the ProgramPoint. Simplify it by just passing the ProgramPoint to CheckerContext. The ProgramPoint can only change if a checker tags it, in which case, we create a copy with the given tag. (A step closer to making CheckerContext work with all node builders, not only StmtNodeBuilder.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141417 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] Remove the last dependency on CheckerContext::getNodeBuilder() as ↵Anna Zaks
well as the method itself. Checkers should not directly access NodeBuilder, nodes can be created by calling the CheckerContext's generateNode() methods. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141249 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
2011-10-04[analyzer] Removing more references to CheckerContext::getNodeBuilder(): ask ↵Anna Zaks

2011-10-03[analyzer] In UndefBranchChecker, use a node generator which does not create ↵Anna Zaks
an edge/branching. (ExprEngine should be in charge of generating edges. The checkers should examine the condition and generate PostCondition node if needed.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141034 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

2011-09-22ST->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).
