Sebastian Redl effa8d1c97 Modify the move emulation according to the excellent design of Howard Hinnant. Makes for much nicer syntax when smart pointers are used consistently. Also, start converting internal argument passing of Parser to smart pointers.

Chris Lattner 90b93d6f69 Fix PR3172: if we see an eof or } at the top level, reject it.
This is important because ParseDeclarationOrFunctionDefinition
skips to, but does not consume, an } on error.

Douglas Gregor 72c3f314d9 Representation of template type parameters and non-type template
parameters, with some semantic analysis:
  - Template parameters are introduced into template parameter scope
  - Complain about template parameter shadowing (except in Microsoft mode)

Note that we leak template parameter declarations like crazy, a
problem we'll remedy once we actually create proper declarations for
templates. 

Next up: dependent types and value-dependent/type-dependent
expressions.

Chris Lattner 3cbfe2c415 Split the DiagnosticInfo class into two disjoint classes:
one for building up the diagnostic that is in flight (DiagnosticBuilder)
and one for pulling structured information out of the diagnostic when
formatting and presenting it.

There is no functionality change with this patch.

Argyrios Kyrtzidis 08b2c3743a Fix this:
With this snippet:
  void f(a::b);

An assert is hit:
Assertion failed: CachedTokens[CachedLexPos-1].getLocation() == Tok.getAnnotationEndLoc() && "The annotation should be until the most recent cached token", file ..\..\lib\Lex\PPCaching.cpp, line 98

Introduce Preprocessor::RevertCachedTokens that reverts a specific number of tokens when backtracking is enabled.

Chris Lattner 1ab3b96de1 Change a couple of the Parser::Diag methods to return DiagnosticInfo
and let the clients push whatever they want into the DiagnosticInfo
instead of hard coding a few forms.  Also switch various clients to
use Diag(Tok, ...) instead of Diag(Tok.getLocation(), ...) as the
canonical form to simplify the code a bit.


git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59509 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-18 07:48:38 +00:00
Chris Lattner 0a14eee528 This reworks some of the Diagnostic interfaces a bit to change how diagnostics
are formed.  In particular, a diagnostic with all its strings and ranges is now
packaged up and sent to DiagnosticClients as a DiagnosticInfo instead of as a 
ton of random stuff.  This has the benefit of simplifying the interface, making
it more extensible, and allowing us to do more checking for things like access
past the end of the various arrays passed in.

In addition to introducing DiagnosticInfo, this also substantially changes how 
Diagnostic::Report works.  Instead of being passed in all of the info required
to issue a diagnostic, Report now takes only the required info (a location and 
ID) and returns a fresh DiagnosticInfo *by value*.  The caller is then free to
stuff strings and ranges into the DiagnosticInfo with the << operator.  When
the dtor runs on the DiagnosticInfo object (which should happen at the end of
the statement), the diagnostic is actually emitted with all of the accumulated
information.  This is a somewhat tricky dance, but it means that the 
accumulated DiagnosticInfo is allowed to keep pointers to other expression 
temporaries without those pointers getting invalidated.

This is just the minimal change to get this stuff working, but this will allow
us to eliminate the zillions of variant "Diag" methods scattered throughout
(e.g.) sema.  For example, instead of calling:

  Diag(BuiltinLoc, diag::err_overload_no_match, typeNames,
       SourceRange(BuiltinLoc, RParenLoc));

We will soon be able to just do:

  Diag(BuiltinLoc, diag::err_overload_no_match)
      << typeNames << SourceRange(BuiltinLoc, RParenLoc));

This scales better to support arbitrary types being passed in (not just 
strings) in a type-safe way.  Go operator overloading?!

2008-11-18 07:04:44 +00:00
Chris Lattner 2383b7f6ae Change the diagnostics interface to take an array of pointers to
strings instead of array of strings.  This reduces string copying
in some not-very-important cases, but paves the way for future 
improvements.

Douglas Gregor 10bd368824 Eliminate all of the placeholder identifiers used for constructors,
destructors, and conversion functions. The placeholders were used to
work around the fact that the parser and some of Sema really wanted
declarators to have simple identifiers; now, the code that deals with
declarators will use DeclarationNames.

Argyrios Kyrtzidis 73a0d889ed Implement support for C++ direct initializers in declarations, e.g. "int x(1);".
This is how this kind of initializers appear in the AST:
-The Init expression of the VarDecl is a functional type construction (of the VarDecl's type).
-The new VarDecl::hasCXXDirectInitializer() returns true.

e.g, for "int x(1);":
-VarDecl 'x' has Init with expression "int(1)" (CXXFunctionalCastExpr).
-hasCXXDirectInitializer() of VarDecl 'x' returns true.

A major benefit is that clients that don't particularly care about which exactly form was the initializer can handle both cases without special case code.
Note that codegening works now for "int x(1);" without any changes to CodeGen.

Daniel Dunbar 662e8b5647 Change Parser & Sema to use interned "super" for comparions.
- Added as private members for each because it is not clear where to
   put the common definition. Perhaps the IdentifierInfos all of these
   "pseudo-keywords" should be collected into one place (this would
   KnownFunctionIDs and Objective-C property IDs, for example).

   so.

- ActOnDeclarator now takes an additional parameter which is the
   AsmLabel if used. Its unfortunate that this bubbles up this high,
   but we cannot just lump it in as an attribute without mistakenly
   *accepting* it as an attribute.
 - The actual asm-label itself is, however, encoded as an AsmLabelAttr
   on the FunctionDecl.
 - Slightly improved parser error recovery on malformed asm-labels.
 - CodeGen support still missing...

missing from function definitions only.  If we see a function 
definiton with missing declspecs, just fudge in an int.

Chris Lattner bda0b626e7 Make a major restructuring of the clang tree: introduce a top-level
lib dir and move all the libraries into it.  This follows the main
llvm tree, and allows the libraries to be built in parallel.  The
top level now enforces that all the libs are built before Driver,
but we don't care what order the libs are built in.  This speeds
up parallel builds, particularly incremental ones.
