* Teach the CXCodeCompleteResults results structure, which storesDouglas Gregor2011-02-161-1/+11
| | | | | | | | | 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. Fixes <rdar://problem/8997369>. llvm-svn: 125678
* Give some convenient idiomatic accessors to Stmt::child_range andJohn McCall2011-02-131-2/+1
| | | | | | | Stmt::const_child_range, then make a bunch of places use them instead of the individual iterator accessors. llvm-svn: 125450

* Remove vtables from the Stmt hierarchy; this was pretty easy asJohn McCall2011-02-091-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 125183
* CMake: libclang shall be named libclang.so, not liblibclang.so.Oscar Fuentes2011-02-051-0/+1
| | | | | | | It is not possible to simply change that target name to `clang' because we already have one. llvm-svn: 124972
* Don't crash when generating USRs for ObjC methods in protocols.Ted Kremenek2011-02-051-8/+13
| | | | llvm-svn: 124920
* USRs for Objective-C methods use the USR of the @interface as their base, ↵Ted Kremenek2011-02-041-18/+6
| | | | | | not the USR of the class category or extension. llvm-svn: 124859
* Teach SourceManager::getLocation() how to cope with a source fileDouglas Gregor2011-02-031-4/+14
| | | | | | | | | | | | | | | | 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(). llvm-svn: 124800

* Allocate CodeCompletionString and all of its components in aDouglas Gregor2011-02-011-48/+26
| | | | | | | | | | | | 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. llvm-svn: 124673
* Add libclang functions to determine the const/volatile/restrictDouglas Gregor2011-01-273-0/+21
| | | | | | qualifiers on a CXType. Patch from Stefan Seefeld, test by me. llvm-svn: 124377
* Eliminate the use of getTypeForDecl from clang_getCursorType() andDouglas Gregor2011-01-241-19/+20
| | | | | | | | clang_getDeclObjCTypeEncoding(); use ASTContext's methods instead, which will (lazily) create the type as needed. Otherwise, we can end up with null QualTypes. llvm-svn: 124133

* Introduce a new kind of TemplateName that captures a substitutedDouglas Gregor2011-01-151-0/+5
| | | | | | | | | | | | | | | 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. llvm-svn: 123521
* Introduce a new expression kind, SubstNonTypeTemplateParmPackExpr,Douglas Gregor2011-01-152-0/+4
| | | | | | | | | that captures the substitution of a non-type template argument pack for a non-type template parameter pack within a pack expansion that cannot be fully expanded. This follows the approach taken by SubstTemplateTypeParmPackType. llvm-svn: 123506
* Renamed CXXBaseOrMemberInitializer to CXXCtorInitializer. This is both shorter,Alexis Hunt2011-01-081-8/+8
| | | | | | | more accurate, and makes it make sense for it to hold a delegating constructor call. llvm-svn: 123084
* Replace the representation of template template argument packDouglas Gregor2011-01-052-2/+5
| | | | | | | | | | | | | expansions with something that is easier to use correctly: a new template argment kind, rather than a bit on an existing kind. Update all of the switch statements that deal with template arguments, fixing a few latent bugs in the process. I"m happy with this representation, now. And, oh look! Template instantiation and deduction work for template template argument pack expansions. llvm-svn: 122896
* Implement the sizeof...(pack) expression to compute the length of aDouglas Gregor2011-01-042-1/+3
| | | | | | | | | parameter pack. Note that we're missing proper libclang support for the new SizeOfPackExpr expression node. llvm-svn: 122813
* Implement support for pack expansions whose pattern is a non-typeDouglas Gregor2011-01-031-0/+1
| | | | | | | | | | | | | | | | | 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. llvm-svn: 122751

* The -fshort-wchar option causes wchar_t to become unsigned, in addition to beingChris Lattner2010-12-253-4/+7
| | | | | | | 16-bits in size. Implement this by splitting WChar into two enums, like we have for char. This fixes a miscompmilation of XULRunner, PR8856. llvm-svn: 122558

* When determining which preprocessed entities to traverse in libclang,Douglas Gregor2010-12-211-1/+14

* Teach clang_getCursorSemanticParent() andDouglas Gregor2010-12-211-3/+29
| | | | | | | | clang_getCursorLexicalParent() to cope with class and function templates, along with the parent of the translation unit. Fixes PR8761 and PR8766. llvm-svn: 122324
* Clean up the handling of template argument packs, especially in theDouglas Gregor2010-12-201-4/+1
| | | | | | | area of printing template arguments. The functionality changes here are limited to cases of variadic templates that aren't yet enabled. llvm-svn: 122250
* Introduce a new type, PackExpansionType, to capture types that areDouglas Gregor2010-12-201-0/+5
| | | | | | | | | | | | | | | | | | | | pack expansions, e.g. given template<typename... Types> struct tuple; template<typename... Types> struct tuple_of_refs { typedef tuple<Types&...> types; }; the type of the "types" typedef is a PackExpansionType whose pattern is Types&. This commit introduces support for creating pack expansions for template type arguments, as above, but not for any other kind of pack expansion, nor for any form of instantiation. llvm-svn: 122223

* Eliminate the branching in QualType::getTypePtr() by providing aDouglas Gregor2010-12-101-6/+6
| | | | | | | | | | | | | | | | | | | | common base for ExtQuals and Type that stores the underlying type pointer. This results in a 2% performance win for -emit-llvm on a typical C file, with 1% memory growth in the AST. Note that there is an API change in this optimization: QualType::getTypePtr() can no longer be invoked on a NULL QualType. If the QualType might be NULL, use QualType::getTypePtrOrNull(). I've audited all uses of getTypePtr() in the code base and changed the appropriate uses over to getTypePtrOrNull(). A future optimization opportunity would be to distinguish between cast/dyn_cast and cast_or_null/dyn_cast_or_null; for the former, we could use getTypePtr() rather than getTypePtrOrNull(), to take another branch out of the cast/dyn_cast implementation. llvm-svn: 121489
