Argyrios Kyrtzidis 52f04650ae [analyzer] Add 'bool ignorePrefix' parameter to cocoa::deriveNamingConvention to control whether
the prefix should be ignored.

E.g. if ignorePrefix is true, "_init" and "init" selectors will both be result in InitRule, but if
ignorePrefix is false, only "init" will return InitRule.

Douglas Gregor b837ea4eee Implement C++ [temp.func.order]p5 more directly, by passing down the
number of explicit call arguments. This actually fixes an erroneous
test for [temp.deduct.partial]p11, where we were considering
parameters corresponding to arguments beyond those that were
explicitly provided.

Douglas Gregor 5cde386e5e When mapping from a function parameter pack to the set of function
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.

Douglas Gregor a8bac7f514 Work-in-progress implementation of C++0x [temp.arg.explicit]p9, which
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.

Douglas Gregor f30101186f Implement substitution of a function parameter pack for its set of
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;

Douglas Gregor df50b8448c When default-initializing a TemplateArgumentLocInfo, make sure that we
initialize *all* of the bits to zero. Also, when the pattern of a
template argument pack expansion, make sure to set the ellipsis

Douglas Gregor 5499af4ef9 Initial implementation of function parameter packs. This implementation allows:
1) Declaration of function parameter packs
  2) Instantiation of function parameter packs within function types.
  3) Template argument deduction of function parameter packs when
  matching two function types.

We're missing all of the important template-instantiation logic for
function template definitions, along with template argument deduction
from the argument list of a function call, so don't even think of
trying to use these for real yet.

Douglas Gregor e4ff4b56fe Replace the representation of template template argument pack
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.

2011-01-05 18:58:31 +00:00
Douglas Gregor eb29d18e5d Add semantic analysis for the creation of and an AST representation
for template template argument pack expansions. This allows fun such
as: 

  template<template<class> class ...> struct apply_impl { /*...*/ };
  template<template<class> class ...Metafunctions> struct apply {
    typedef typename apply_impl<Metafunctions...>::type type;
  };

However, neither template argument deduction nor template
instantiation is implemented for template template argument packs, so
this functionality isn't useful yet.

I'll probably replace the encoding of template template
argument pack expansions in TemplateArgument so that it's harder to
accidentally forget about the expansion. However, this is a step in
the right general direction.

John McCall 3882ace207 Refactor the application of type attributes so that attributes from
the declaration-specifiers and on the declarator itself are moved
to the appropriate declarator chunk.  This permits a greatly
simplified model for how to apply these attributes, as well as
allowing a much more efficient query for the GC attribute.
Now all qualifier queries follow the same basic strategy of
"local qualifiers, local qualifiers on the canonical type,
then look through arrays".  This can be easily optimized by
changing the canonical qualified-array-type representation.

Do not process type attributes as decl attributes on declarations
with declarators.

When computing the type of a block, synthesize a prototype
function declarator chunk if the decl-spec type was not a
function.  This simplifies the logic for building block signatures.

Change the logic which inserts an objc_read_weak on a block
literal to only fire if the block has a __weak __block variable,
rather than if the return type of the block is __weak qualified,
which is not actually a sensible thing to ask.

Douglas Gregor ca4686dc38 Improve our handling of non-type template parameters in partial
specializations. We weren't dealing with any of the cases where the
type of the non-type template argument differs from the type of the
corresponding template parameter in the primary template. We would
think that the template parameter in the partial specialization was
not deducible (and warn about it, incorrectly), then fail to convert a
deduced parameter to the type of the template parameter in the partial
specialization (which may involve truncation, among other
things). Fixes PR8905.
