* [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
* [analyzer] Add getLocationContext to CheckerContextAnna Zaks2011-10-261-1/+1
| | | | | | | CheckerContext::getPredecessor is only used to get to the LocationContext half of the times. llvm-svn: 143061
* [analyzer] Rename generateNode -> addTransition in CheckerContextAnna Zaks2011-10-261-1/+1
| | | | | | Also document addTransition methods. llvm-svn: 143059
* [analyze] Convert EndOfPath callback to use CheckerContextAnna Zaks2011-10-251-13/+13
| | | | | | | | Get rid of the EndOfPathBuilder completely. Use the generic NodeBuilder to generate nodes. Enqueue the end of path frontier explicitly. llvm-svn: 142943
* Change operator<< for raw_ostream and NamedDecl to take a reference instead ↵Benjamin Kramer2011-10-141-1/+1
| | | | | | | | of a pointer. Passing a pointer was a bad idea as it collides with the overload for void*. llvm-svn: 141971

* Handle CXXTempObjectRegion in StackAddrEscapeChecker.Jeffrey Yasskin2011-08-261-0/+5
| | | | | | | | Also convert stack-addr-ps.cpp to use the analyzer instead of just Sema, now that it doesn't crash, and extract the stack-block test into another file since it errors, and that prevents the analyzer from running. llvm-svn: 138613
* [analyzer] Replace calls to getNameAsString() with StringRef equivalents.Jordy Rose2011-08-211-1/+1

* Remove EnhancedBugReport and RangedBugReport - pull all the extra ↵Anna Zaks2011-08-171-2/+2
| | | | | | 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. llvm-svn: 137894
* Rename GRState to ProgramState, and cleanup some code formatting along the way.Ted Kremenek2011-08-151-2/+2

* Cleanup various declarations of 'Stmt*' to be 'Stmt *', etc. in libAnalyzer ↵Ted Kremenek2011-08-121-2/+2
| | | | | | and libStaticAnalyzer[*]. It was highly inconsistent, and very ugly to look at. llvm-svn: 137537

| | | | | | | | LLVM.h imports them into the clang namespace. llvm-svn: 135852
* Automatic Reference Counting.John McCall2011-06-151-4/+16
| | | | | | | | | | Language-design credit goes to a lot of people, but I particularly want to single out Blaine Garst and Patrick Beard for their contributions. Compiler implementation credit goes to Argyrios, Doug, Fariborz, and myself, in no particular order. llvm-svn: 133103
