John McCall 28a6aeab7e Change our basic strategy for avoiding deprecation warnings when the decl use
appears in a deprecated context.  In the new strategy, we emit the warnings
as usual unless we're currently parsing a declaration, where "declaration" is
restricted to mean a decl group or a few special cases in Objective C.  If
we *are* parsing a declaration, we queue up the deprecation warnings until
the declaration has been completely parsed, and then emit them only if the
decl is not deprecated.
We also standardize the bookkeeping for deprecation so as to avoid special cases.

Douglas Gregor 71395fa1d5 Implement support for parsing dependent template-ids that refer to

Douglas Gregor 3cf81317e4 Parsing and semantic analysis for template-ids that name overloaded
operators, e.g., 

  operator+<int>

which now works in declarators, id-expressions, and member access
expressions. This commit only implements the non-dependent case, where
we can resolve the template-id to an actual declaration.

Douglas Gregor 30d60cb36e Replace the code that parses member access expressions after "." or
"->" with a use of ParseUnqualifiedId. Collapse
ActOnMemberReferenceExpr, ActOnDestructorReferenceExpr (both of them),
ActOnOverloadedOperatorReferenceExpr,
ActOnConversionOperatorReferenceExpr, and
ActOnMemberTemplateIdReferenceExpr into a single, new action
ActOnMemberAccessExpr that does the same thing more cleanly (and can
keep more source-location information).

John McCall d5a36321b9 Reorganize the parsing of decl groups / function definitions so that

these cases).  Remove some excess diagnostics arising during parse failures.

Douglas Gregor a121b75d9d Use ParseUnqualifiedId when parsing id-expressions. This eliminates
yet another copy of the unqualified-id parsing code.

Also, use UnqualifiedId to simplify the Action interface for building
id-expressions. ActOnIdentifierExpr, ActOnCXXOperatorFunctionIdExpr,
ActOnCXXConversionFunctionExpr, and ActOnTemplateIdExpr have all been
removed in favor of the new ActOnIdExpression action.

John McCall cfefb6d197 Switch ParseStructDeclaration to a callback-based API. This will make
it easier to track within Sema whether the parser is parsing a declaration.

Douglas Gregor 7861a80346 Introduce a new class, UnqualifiedId, that provides a parsed
representation of a C++ unqualified-id, along with a single parsing
function (Parser::ParseUnqualifiedId) that will parse all of the
various forms of unqualified-id in C++.

Replace the representation of the declarator name in Declarator with
the new UnqualifiedId class, simplifying declarator-id parsing
considerably and providing more source-location information to
Sema. In the future, I hope to migrate all of the other
unqualified-id-parsing code over to this single representation, then
begin to merge actions that are currently only different because we
didn't have a unqualified notion of the name in the parser.

Chris Lattner 17e15f18c5 simplify Sema::getTypeName a bit: if control gets out of the switch,
IIDecl cannot be null.  There is no need to check for both C++ mode and
presence of CXXRecordDecl.  ObjC interfaces can't have ScopeSpecs.

Chris Lattner 5566290b34 In objc mode, every identifier in a cast expression was using doing a
type looking using getTypeName() and every property access was using
NextToken() to do lookahead to see if the identifier is followed by
a '.'.  Rearrange this code to not need lookahead and only do the
type lookup if we have "identifier." in the token stream.  Also
improve a diagnostic a bit.

Douglas Gregor d019ff686c When building and instantiating a template-id reference expression, such as
N::f<int>

keep track of the full nested-name-specifier. This is mainly QoI and
relatively hard to test; will try to come up with a printing-based
test once we also retain the explicit template arguments past overload
resolution.

Douglas Gregor 15e5602e59 Improve diagnostics when the parser encounters a declarator with an
unknown type name, e.g.,

  foo::bar x;

when "bar" does not refer to a type in "foo". 

With this change, the parser now calls into the action to perform
diagnostics and can try to recover by substituting in an appropriate
type. For example, this allows us to easily diagnose some missing
"typename" specifiers, which we now do:

  test/SemaCXX/unknown-type-name.cpp:29:1: error: missing 'typename'
        prior to dependent type name 'A<T>::type'
  A<T>::type A<T>::f() { return type(); }
  ^~~~~~~~~~
  typename 

Fixes PR3990.

Douglas Gregor 2208a2912c Simplify the handling of non-dependent friend class template
specializations such as:

  friend class std::vector<int>;

by using the same code path as explicit specializations, customized to
reference an existing ClassTemplateSpecializationDecl (or build a new
"undeclared" one).

Douglas Gregor 3dad842b35 Rework the Parse-Sema interaction for friends to better support friend

template void f<int>(int);
                ~~~~~~
Previously, we silently dropped the template arguments. With this
change, we now use the template arguments (when available) as the
explicitly-specified template arguments used to aid template argument
deduction for explicit template instantiations.

2009-09-22 21:41:40 +00:00
Douglas Gregor cabea40ea3 Implement code completion within a function call, triggered after the
opening parentheses and after each comma. We gather the set of visible
overloaded functions, perform "partial" overloading based on the set
of arguments that we have thus far, and return the still-viable
results sorted by the likelihood that they will be the best candidate.

Most of the changes in this patch are a refactoring of the overloading
routines for a function call, since we needed to separate out the
notion of building an overload set (common to code-completion and
normal semantic analysis) and then what to do with that overload
set. As part of this change, I've pushed explicit template arguments
into a few more subroutines.

There is still much more work to do in this area. Function templates
won't be handled well (unless we happen to deduce all of the template
arguments before we hit the completion point), nor will overloaded
function-call operators or calls to member functions.
