* [analyzer] introduce getSVal(Stmt *) helper on ExplodedNode, make sure the ↵George Karpenkov2018-01-171-1/+1
| | | | | | | | | | | | | | | | | | helper is used consistently In most cases using `N->getState()->getSVal(E, N->getLocationContext())` is ugly, verbose, and also opens up more surface area for bugs if an inconsistent location context is used. This patch introduces a helper on an exploded node, and ensures consistent usage of either `ExplodedNode::getSVal` or `CheckContext::getSVal` across the codebase. As a result, a large number of redundant lines is removed. Differential Revision: https://reviews.llvm.org/D42155 llvm-svn: 322753

* [analyzer] Add generateErrorNode() APIs to CheckerContext.Devin Coughlin2015-09-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The analyzer trims unnecessary nodes from the exploded graph before reporting path diagnostics. However, in some cases it can trim all nodes (including the error node), leading to an assertion failure (see https://llvm.org/bugs/show_bug.cgi?id=24184). This commit addresses the issue by adding two new APIs to CheckerContext to explicitly create error nodes. Unless the client provides a custom tag, these APIs tag the node with the checker's tag -- preventing it from being trimmed. The generateErrorNode() method creates a sink error node, while generateNonFatalErrorNode() creates an error node for a path that should continue being explored. The intent is that one of these two methods should be used whenever a checker creates an error node. This commit updates the checkers to use these APIs. These APIs (unlike addTransition() and generateSink()) do not take an explicit Pred node. This is because there are not any error nodes in the checkers that were created with an explicit different than the default (the CheckerContext's Pred node). It also changes generateSink() to require state and pred nodes (previously these were optional) to reduce confusion. Additionally, there were several cases where checkers did check whether a generated node could be null; we now explicitly check for null in these places. This commit also includes a test case written by Ying Yi as part of http://reviews.llvm.org/D12163 (that patch originally addressed this issue but was reverted because it introduced false positive regressions).

* Expose the name of the checker producing each diagnostic message.Alexander Kornienko2014-02-111-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: In clang-tidy we'd like to know the name of the checker producing each diagnostic message. PathDiagnostic has BugType and Category fields, which are both arbitrary human-readable strings, but we need to know the exact name of the checker in the form that can be used in the CheckersControlList option to enable/disable the specific checker. This patch adds the CheckName field to the CheckerBase class, and sets it in the CheckerManager::registerChecker() method, which gets them from the CheckerRegistry. Checkers that implement multiple checks have to store the names of each check in the respective registerXXXChecker method.

I also manually added quite a few missing headers that were uncovered by shuffling the order or moving headers up to be main-module-headers. llvm-svn: 169237

* [analyzer] Make the entries in 'Environment' context-sensitive by making ↵Ted Kremenek2012-01-061-1/+1
| | | | | | | | | | | | | | | | | | 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). llvm-svn: 147688
