2011-01-11When mapping from a function parameter pack to the set of functionDouglas Gregor
parameters it expanded to, map exactly the number of function parameters that were expanded rather than just running to the end of the instantiated parameter list. This finishes the implementation of the last sentence of C++0x [temp.deduct.call]p1. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123213 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-11Implement the last bullet of [temp.deduct.type]p5 and part of the lastDouglas Gregor
sentence of [temp.deduct.call]p1, both of which concern the non-deducibility of parameter packs not at the end of a parameter-type-list. The latter isn't fully implemented yet; see the new FIXME. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123210 91177308-0d34-0410-b5e6-96231b3b80d8
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
2011-01-08Renamed CXXBaseOrMemberInitializer to CXXCtorInitializer. This is both shorter,Sean Hunt
more accurate, and makes it make sense for it to hold a delegating constructor call. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123084 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-07When instantiating the arguments to an initializer, use theDouglas Gregor
TreeTransform version of TransformExprs() rather than explicit loop, so that we expand pack expansions properly. Test cast coming soon... git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123014 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-07Implement substitution of a function parameter pack for its set ofDouglas Gregor
instantiated function parameters, enabling instantiation of arbitrary pack expansions involving function parameter packs. At this point, we can now correctly compile a simple, variadic print() example: #include <iostream> #include <string> void print() {} template<typename Head, typename ...Tail> void print(const Head &head, const Tail &...tail) { std::cout << head; print(tail...); } int main() { std::string hello = "Hello"; print(hello, ", world!", " ", 2011, '\n'); } git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123000 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-05Implement support for template template parameter packs, e.g.,Douglas Gregor

2011-01-04Implement pack expansion of base initializers, so that we canDouglas Gregor

2010-12-23Add an AST representation for non-type template parameterDouglas Gregor
packs, e.g., template<typename T, unsigned ...Dims> struct multi_array; along with semantic analysis support for finding unexpanded non-type template parameter packs in types, expressions, and so on. Template instantiation involving non-type template parameter packs probably doesn't work yet. That'll come soon. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@122527 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-22Implement template argument deduction for pack expansions whoseDouglas Gregor
pattern is a template argument, which involves repeatedly deducing template arguments using the pattern of the pack expansion, then bundling the resulting deductions into an argument pack. We can now handle a variety of simple list-handling metaprograms using variadic templates. See, e.g., the new "count" metaprogram. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@122439 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-25Tie DefineVTablesUsed() in with recursive function instantiation so that we emitNick Lewycky
a useful template instantiation stack. Fixes PR8640. This also causes a slight change to where the "instantianted from" note shows up in truly esoteric cases (see the change to test/SemaCXX/destructor.cpp), but that isn't directly the fault of this patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120135 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

2010-11-07Remove broken support for variadic templates, along with the variousDouglas Gregor
abstractions (e.g., TemplateArgumentListBuilder) that were designed to support variadic templates. Only a few remnants of variadic templates remain, in the parser (parsing template type parameter packs), AST (template type parameter pack bits and TemplateArgument::Pack), and Sema; these are expected to be used in a future implementation of variadic templates. But don't get too excited about that happening now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@118385 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-17When emitting a new-expression inside a conditional expression,John McCall
the cleanup might not be dominated by the allocation code. In this case, we have to store aside all the delete arguments in case we need them later. There's room for optimization here in cases where we end up not actually needing the cleanup in different branches (or being able to pop it after the initialization code). Also make sure we only call this operator delete along the path where we actually allocated something.
