2008-04-13This patch adds very basic support for parsing and type-checking classDouglas Gregor
inheritance in C++. It'll parse the base-specifier list, e.g., class D : public B1, virtual public B2 { }; and do some of the simpler semantic checks (B1 and B2 are classes; they aren't unions or incomplete types, etc). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49623 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-13Test commit: fix a typoDouglas Gregor

2008-04-13This patch is just the easy part of the class names patch, whichChris Lattner
allows the parsing of "class" in addition to "struct" and "union" to declare a record. So this patch allows: class C { }; class C c1; But it does not contain the lookup bits, so this won't work yet: C c2; Patch by Doug Gregor! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49613 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-13Change the btree algorithm to split nodes bottom-up instead of top-down.Chris Lattner
This results in an (IMO) simpler algorithm, results in fewer splits, and is more amenable to delta handling (there is no reason to mutate the tree at all when adding a delta to a position that already exists in the tree). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49609 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-12Do an initial hack at replacing one of the incredibly inefficient Chris Lattner
(but simple!) datastructures in the rewriter with a more complex but more efficient one. This replaces the Deltas vector with a specialized BTree that makes delta lookups much more efficient. This speeds up -emit-html on a 500K .i file from 157.154 to 27.127 seconds on my machine (5.8x). While this code is functional, it isn't very pretty, I have much refactoring planned for it, and will remove the USE_VECTOR ifdef. Stay tuned. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49586 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-11Add some boilerplate to report memory leaks at the end of an analyzed function.Ted Kremenek
Still need some boilerplate in BugReporter to report bugs at the end of a function (not associated with a particular statement). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49564 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-11Changed behavior of how we handle "NULL" summaries: just callTed Kremenek
GRSimpleVals::EvalCal(), and don't change reference counts. Remove "getDoNothingSummary()", as a NULL summary does the same thing. Added temporary hack for the "Get" rule for objects that return a pointer type: treat them as non-owned CF objects. Added test case to detect the release of a non-owned object. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49555 91177308-0d34-0410-b5e6-96231b3b80d8
