John McCall 85f9055955 When pretty-printing tag types, only print the tag if we're in C (and
therefore not creating ElaboratedTypes, which are still pretty-printed
with the written tag).

Most of these testcase changes were done by script, so don't feel too
sorry for my fingers.

John McCall e78aac41de Create a new InjectedClassNameType to represent bare-word references to the
injected class name of a class template or class template partial specialization.
This is a non-canonical type;  the canonical type is still a template 
specialization type.  This becomes the TypeForDecl of the pattern declaration,
which cleans up some amount of code (and complicates some other parts, but
whatever).

Fixes PR6326 and probably a few others, primarily by re-establishing a few
invariants about TypeLoc sizes.

Douglas Gregor 61f6db54e1 Switch CodeGen's "is this variable declaration a definition?" logic
over to VarDecl::isThisDeclarationADefinition(), which handles
variables declared with linkage specifications better (among other
things). CMake 2.9 (from CVS) now builds with clang++ and is somewhat
functional.

Douglas Gregor 6791a0d43b Improve handling of enumerator values for C and C++, including:
- In C++, prior to the closing '}', set the type of enumerators
    based on the type of their initializer. Don't perform unary
    conversions on the enumerator values.
  - In C++, handle overflow when an enumerator has no initializer and
    its value cannot be represented in the type of the previous
    enumerator.
  - In C, handle overflow more gracefully, by complaining and then
    falling back to the C++ rules.
  - In C, if the enumerator value is representable in an int, convert the
    expression to the type 'int'.

Fixes PR5854 and PR4515.

Douglas Gregor d615026e8d C++0x [dcl.typedef]p4, take 3, where we actually figure out what "that
is not also a typedef-name" actually means. For anyone keeping score,
that's John: 2, Doug: 0.

Douglas Gregor 323ade5ac8 Use isa<ElaboratedType> rather than getAs<ElaboratedType>, since the
latter may (eventually) perform multiple levels of desugaring (thus
breaking the newly-added tests) and the former is faster. Thanks, John!

Douglas Gregor 9dd13ab202 Allow redefinitions of typedef-names within class scope when the type
they redefine is a class-name but not a typedef-name, per C++0x
[dcl.typedef]p4. The code in the test was valid C++98 and is valid
C++0x, but an unintended consequence of DR56 made it ill-formed in
C++03 (which we were luck enough to implement). Fixes PR5455.

John McCall 64fe233704 When parsing an identifier as an expression in C++, only try to annotate it
as a type or scope token if the next token requires it.

This eliminates a lot of redundant lookups in C++, but there's room for
improvement;  a better solution would do a single lookup whose kind and
results would be passed through the parser.

Daniel Dunbar 5618e98f33 Update tests to use %clang instead of 'clang', and forcibly disable use of '
clang ' or ' clang -cc1 ' or ' clang-cc ' in test lines (by substituting them to
garbage).

2009-12-15 22:01:24 +00:00
Daniel Dunbar 8fbe78f6fc Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
- This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).

John McCall 7a2865a217 Actually try to trigger the last diagnostic in the declaration-collision test case.
Surprisingly, we *do* diagnose one of them.  Since we don't really track scopes into
instantiation, this has to signal some kind of bug.

John McCall e29c5cd239 Improve the diagnostic when a new declaration conflicts with a using shadow
declaration.  Rename note_using_decl to note_using, which is possibly less confusing.
Add a test for non-class-scope using decl collisions and be sure to note the case
we can't diagnose yet.

John McCall 84d8767c15 Implement redeclaration checking and hiding semantics for using declarations. There
are a couple of O(n^2) operations in this, some analogous to the usual O(n^2)
redeclaration problem and some not.  In particular, retroactively removing
shadow declarations when they're hidden by later decls is pretty unfortunate.
I'm not yet convinced it's worse than the alternative, though.

John McCall 6e9f8f6374 Honor using declarations in overload resolution. Most of the code for
overloaded-operator resolution is wildly untested, but the parallel code for
methods seems to satisfy some trivial tests.

Also change some overload-resolution APIs to take a type instead of an expression,
which lets us avoid creating a spurious CXXThisExpr when resolving implicit
member accesses.

John McCall e61f2ba7e4 Incremental progress on using declarations. Split UnresolvedUsingDecl into
two classes, one for typenames and one for values;  this seems to have some
support from Doug if not necessarily from the extremely-vague-on-this-point
standard.  Track the location of the 'typename' keyword in a using-typename
decl.  Make a new lookup result for unresolved values and deal with it in
most places.

John McCall 9757d0363d Make a somewhat more convincing test case for unqualified lookup through
using directives, and fix a bug thereby exposed:  since we're playing
tricks with pointers, we need to make certain we're always using the same

Also tweak an existing error message.

Douglas Gregor 3dad842b35 Rework the Parse-Sema interaction for friends to better support friend
class templates. We now treat friend class templates much more like
normal class templates, except that they still get special name lookup

<iostream>.

John McCall 1806c2795b Track a class template specialization's point of instantiation separately

When implicitly creating a declaration of a class template specialization

location instead of the location of the first reference.
