John McCall cef1582923 Support __attribute__((unused)) on types. This suddenly started firing
a lot for me on selfhosts, I dunno why.

Douglas Gregor d7f18dd750 Drastically simplify the computation of linkage for typeinfo by using
the existing (and already well-tested) linkage computation for types,
with minor tweaks for dynamic classes and (pointers to) incomplete
types. Fixes PR6597.

John McCall d9c7c6568e Introduce a new kind of derived-to-base cast which bypasses the need for

members.

Argyrios Kyrtzidis 998d51b98f When "delayed parsing" C++ default arguments, if there is an error, there may be tokens left in the token stream
that will interfere (they will be parsed as if they are after the class' '}') and a crash will occur because
the CachedTokens that holds them will be deleted while the lexer is still using them.

Make sure that the tokens of default args are removed from the token stream.
Fixes PR6647.

Douglas Gregor 504662f28f Add a test for C++ [stmt.select]p3, which specifies that redeclaring a
name in the outermost block of a if/else that declares the same name
is ill-formed. Turns out that Clang and MSVC were right about PR6739;
GCC is too lax.

John McCall 16df1e59f2 Propagate the "found declaration" (i.e. the using declaration instead of
the underlying/instantiated decl) through a lot of API, including "intermediate"
MemberExprs required for (e.g.) template instantiation.  This is necessary
because of the access semantics of member accesses to using declarations:
only the base class *containing the using decl* need be accessible from the
naming class.

This allows us to complete an access-controlled selfhost, if there are no
recent regressions.

Douglas Gregor 607f14168a Improve diagnostics when printing a template instantiation backtrace
involving substitution of deduced template arguments into a class
template partial specialization or function template, or when

user can see what got deduced.

Rafael Espindola c50c27cca8 the big refactoring bits of PR3782.

Anders Carlsson e47380fb19 When collecting virtual bases it's very important to use the canonical type of the base class. Otherwise, we might add the same virtual base class twice if the virtual base is an instantiated template. Fixes PR6251.

Douglas Gregor d5cb1ddb2c After performing template argument deduction for a function template,
check deduced non-type template arguments and template template
arguments against the template parameters for which they were deduced,
performing conversions as appropriate so that deduced template
arguments get the same treatment as explicitly-specified template
arguments. This is the bulk of PR6723.

Also keep track of whether deduction of a non-type template argument
came from an array bound (vs. anywhere else). With this information,
we enforce C++ [temp.deduct.type]p17, which requires exact type
matches when deduction deduces a non-type template argument from
something that is not an array bound.

Finally, when in a SFINAE context, translate the "zero sized
arrays are an extension" extension diagnostic into a hard error (for
better standard conformance), which was a minor part of PR6723.

John McCall 3dc81f77f6 Accumulate all functions and classes that the effective context is
nested within, and suddenly local classes start working.  Wouldn't be
necessary if I hadn't used local classes in Clang in the first place.
Or, well, wouldn't be necessary yet. :)

Douglas Gregor c14922f14a When adding initializers to a constructor, be sure that we are looking
through the bases and fields of the definition of the class in which
the constructor is declared, rather than some other declaration of
that class.

2010-03-26 22:43:07 +00:00
John McCall 93cc732ffc Properly account for redeclarations when explicitly instantiating class templates.
What happens here is that we actually turn the first declaration into a
definition, regardless of whether it was actually originally a definition,
and furthermore we do this all after we've instantiated all the declarations.
This exposes a bug in my DefinitionData patch where it was only setting the
DefinitionData for previous declarations, not future declarations.
Fortunately, there's an iterator for that.

Douglas Gregor f9edf80c39 When trying to determine whether one operand of a conditional
expression can be converted to the type of another, only apply the

conversions. Fixes PR6595.
