2011-02-25Update UsingDecl, UnresolvedUsingTypenameDecl, andDouglas Gregor
UnresolvedUsingValueDecl to use NestedNameSpecifierLoc rather than the extremely-lossy NestedNameSpecifier/SourceRange pair it used to use, improving source-location information. Various infrastructure updates to support NestedNameSpecifierLoc: - AST/PCH (de-)serialization - Recursive AST visitor - libclang traversal (including the first tests of this functionality) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@126459 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-24Teach NestedNameSpecifier to keep track of namespace aliases the sameDouglas Gregor
way it keeps track of namespaces. Previously, we would map from the namespace alias to its underlying namespace when building a nested-name-specifier, losing source information in the process. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@126358 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-20Implement the C++0x deduced 'auto' feature.Richard Smith

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
2011-02-13Give some convenient idiomatic accessors to Stmt::child_range andJohn McCall

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
2011-02-09NonTypeTemplateParmDecl is just a DeclaratorDecl, not a VarDecl.John McCall
Also, reorganize and make very explicit the logic for determining the value kind and type of a referenced declaration. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125150 91177308-0d34-0410-b5e6-96231b3b80d8

thousand other things which were (generally inadvertantly) relying on that. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123814 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-15Introduce a new expression kind, SubstNonTypeTemplateParmPackExpr,Douglas Gregor
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123506 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-14Start implementing support for substitution into pack expansions thatDouglas Gregor
involve template parameter packs at multiple template levels that occur within the signatures members of class templates (and partial specializations thereof). This is a work-in-progress that is deficient in several ways, notably: - It only works for template type parameter packs, but we need to also support non-type template parameter packs and template template parameter packs. - It doesn't keep track of the lengths of the substituted argument packs in the expansion, so it can't properly diagnose length mismatches. However, this is a concrete step in the right direction. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123425 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-11Add testing for unexpanded parameter packs in all of the C++Douglas Gregor

2011-01-10Work-in-progress implementation of C++0x [temp.arg.explicit]p9, whichDouglas Gregor
allows an argument pack determines via explicit specification of function template arguments to be extended by further, deduced arguments. For example: template<class ... Types> void f(Types ... values); void g() { f<int*, float*>(0, 0, 0); // Types is deduced to the sequence int*, float*, int } There are a number of FIXMEs in here that indicate places where we need to implement + test retained expansions, plus a number of other places in deduction where we need to correctly cope with the explicitly-specified arguments when deducing an argument pack. Furthermore, it appears that the RecursiveASTVisitor needs to be auditied; it's missing some traversals (especially w.r.t. template arguments) that cause it not to find unexpanded parameter packs when it should. The good news, however, is that the tr1::tuple implementation now works fully, and the tr1::bind example (both from N2080) is actually working now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123163 91177308-0d34-0410-b5e6-96231b3b80d8

2011-01-06Introduce an AttributedType, but don't actually use it anywhere yet.John McCall

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. 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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@122896 91177308-0d34-0410-b5e6-96231b3b80d8

2011-01-03Implement support for pack expansions whose pattern is a non-typeDouglas Gregor
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
2010-12-22Redesign the way anonymous fields are handled in designated-initializers.Francois Pichet
Previously designated anonymous fields were found via name lookup. This redesign uses the fact that an IndirectFieldDecl declaration will always follow an anonymous implicit field to remove the special case of name lookup. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@122387 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-20Give the RecursiveASTVisitor a configuration functionDouglas Gregor
shouldWalkTypesOfTypeLocs() that determines whether it should walk the Types within TypeLocs. This walk is redundant, but perhaps required for some clients. Disabling this redundant walk in the unexpanded parameter pack finder produces better results, because we get parameter packs with source location info *unless* such source location information isn't available. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@122287 91177308-0d34-0410-b5e6-96231b3b80d8

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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@122223 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-21Major anonymous union/struct redesign.Francois Pichet
A new AST node is introduced: def IndirectField : DDecl<Value>; IndirectFields are injected into the anonymous's parent scope and chain back to the original field. Name lookup for anonymous entities now result in an IndirectFieldDecl instead of a FieldDecl. There is no functionality change, the code generated should be the same. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119919 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-20Get FunctionDecl to recurse on FunctionTypeLoc rather thanCraig Silverstein
FunctionType! I didn't realize it was available, until rjmccall pointed out that DeclaratorDecl made the typeloc available. This makes FunctionDecl recursion *much* easier, because the typeloc can take care of default parameters, so we no longer have to do that separately, which means we can just do a normal type traversal instead of this special-case WalkUp stuff we did before. The only downside -- and it's minor -- is that because the TypeLoc handles both the return type and the argument types, we can't recurse on the explicit template args in the right place (which would be between them). I do it beforehand instead. So for int MyFunc<float>(char x); we get callbacks in the order: float, int, char.
