2011-02-17Begin overhaul of scan-build/ccc-analyzer's handling of checker options.Ted Kremenek
We now rely on 'clang --analyze' to provide the default set of checkers. We're still working on the new '-analyzer-checker <checker>' interface, and once that's ready we'll wire it up to scan-build. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125712 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-16Teach the CXCodeCompleteResults results structure, which storesDouglas Gregor
code-completion results accessed via libclang, to extend the lifetime of the allocator used for cached global code-completion results at least until these completion results are destroyed.

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

It is not possible to simply change that target name to `clang' because we already have one. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124972 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-03Teach SourceManager::getLocation() how to cope with a source fileDouglas Gregor
whose inode has changed since the file was first created and that is being seen through a different path name (e.g., due to symlinks or relative path elements), such that its FileEntry pointer doesn't match a known FileEntry pointer. Since this requires a system call (to stat()), we only perform this deeper checking if we can't find the file by comparing FileEntry pointers. Also, add a micro-optimization where we don't bother to compute line numbers when given the location (1, 1). This improves the efficiency of clang_getLocationForOffset(). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124800 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-01Allocate CodeCompletionString and all of its components in aDouglas Gregor
BumpPtrAllocator, rather than manually new/delete'ing them. This optimization also allows us to avoid allocating memory for and copying constant strings (e.g., "return", "class"). This also required embedding the priority and availability of results within the code completion string, to avoid extra memory allocation within libclang. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124673 91177308-0d34-0410-b5e6-96231b3b80d8

2011-01-15Introduce a new kind of TemplateName that captures a substitutedDouglas Gregor
template template parameter pack that cannot be fully expanded because its enclosing pack expansion could not be expanded. This form of TemplateName plays the same role as SubstTemplateTypeParmPackType and SubstNonTypeTemplateParmPackExpr do for template type parameter packs and non-type template parameter packs, respectively. We should now handle these multi-level pack expansion substitutions anywhere. The largest remaining gap in our variadic-templates support is that we cannot cope with non-type template parameter packs whose type is a pack expansion. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123521 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-15Introduce a new expression kind, SubstNonTypeTemplateParmPackExpr,Douglas Gregor

2011-01-05Replace the representation of template template argument packDouglas Gregor
expansions with something that is easier to use correctly: a new template argment kind, rather than a bit on an existing kind.

template argument (described by an expression, of course). For example: template<int...> struct int_tuple { }; template<int ...Values> struct square { typedef int_tuple<(Values*Values)...> type; }; It also lays the foundation for pack expansions in an initializer-list. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@122751 91177308-0d34-0410-b5e6-96231b3b80d8
