-Introduce CheckerV2, a set of templates for convenient declaration & registration of checkers. Currently useful just for checkers working on the AST not the path-sensitive ones. -Enhance CheckerManager to actually collect the checkers and turn it into the entry point for running the checkers. -Use the new mechanism for the LLVMConventionsChecker. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125778 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-17Change the representation of GNU ?: expressions to use a different expressionJohn McCall
class and to bind the shared value using OpaqueValueExpr. This fixes an unnoticed problem with deserialization of these expressions where the deserialized form would lose the vital pointer-equality trait; or rather, it fixes it because this patch also does the right thing for deserializing OVEs. Change OVEs to not be a "temporary object" in the sense that copy elision is permitted. This new representation is not totally unawkward to work with, but I think that's really part and parcel with the semantics we're modelling here. In particular, it's much easier to fix things like the copy elision bug and to make the CFG look right. I've tried to update the analyzer to deal with this in at least some obvious cases, and I think we get a much better CFG out, but the printing of OpaqueValueExprs probably needs some work. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125744 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-17Step #1/N of implementing support for __label__: split labels intoChris Lattner
LabelDecl and LabelStmt. There is a 1-1 correspondence between the two, but this simplifies a bunch of code by itself. This is because labels are the only place where we previously had references to random other statements, causing grief for AST serialization and other stuff. This does cause one regression (attr(unused) doesn't silence unused label warnings) which I'll address next. This does fix some minor bugs: 1. "The only valid attribute " diagnostic was capitalized. 2. Various diagnostics printed as ''labelname'' instead of 'labelname' 3. This reduces duplication of label checking between functions and blocks. Review appreciated, particularly for the cindex and template bits. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125733 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-14[analyzer] Overhauling of the checker registration mechanism.Argyrios Kyrtzidis
-Checkers will be defined in the tablegen file 'Checkers.td'. -Apart from checkers, we can define checker "packages" that will contain a collection of checkers. -Checkers can be enabled with -analyzer-checker=<name> and disabled with -analyzer-disable-checker=<name> e.g: Enable checkers from 'cocoa' and 'corefoundation' packages except the self-initialization checker: -analyzer-checker=cocoa -analyzer-checker=corefoundation -analyzer-disable-checker=cocoa.SelfInit -Introduces CheckerManager and CheckerProvider. CheckerProviders get the set of checker names to enable/disable and register them with the CheckerManager which will be the entry point for all checker-related functionality. Currently only the self-initialization checker takes advantage of the new mechanism. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125503 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-09Remove vtables from the Stmt hierarchy; this was pretty easy asJohn McCall
there were only three virtual methods of any significance. The primary way to grab child iterators now is with Stmt::child_range children(); Stmt::const_child_range children() const; where a child_range is just a std::pair of iterators suitable for being llvm::tie'd to some locals. I've left the old child_begin() and child_end() accessors in place, but it's probably a substantial penalty to grab the iterators individually now, since the switch-based dispatch is kindof inherently slower than vtable dispatch. Grabbing them together is probably a slight win over the status quo, although of course we could've achieved that with vtables, too. I also reclassified SwitchCase (correctly) as an abstract Stmt class, which (as the first such class that wasn't an Expr subclass) required some fiddling in a few places. There are somewhat gross metaprogramming hooks in place to ensure that new statements/expressions continue to implement getSourceRange() and children(). I had to work around a recent clang bug; dgregor actually fixed it already, but I didn't want to introduce a selfhosting dependency on ToT. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125183 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-09static analyzer: Further reduce the analyzer's memory usage when analyzing ↵Ted Kremenek
sqlite3 by 7-10% by recylcing "uninteresting" ExplodedNodes. The optimization involves eagerly pruning ExplodedNodes from the ExplodedGraph that contain practically no difference between the predecessor and successor nodes. For example, if the state is different between a predecessor and a node, the node is left in. Only for the 'environment' component of the state do we not care if the ExplodedNodes are different. This paves the way for future optimizations where we can reclaim the environment objects. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125154 91177308-0d34-0410-b5e6-96231b3b80d8
