Ted Kremenek b0262c1e64 - Default initialize ParsingPreprocessorDirective, ParsingFilename, and
LexingRawMode in the ctor of PreprocessorLexer.

- PTHLexer: Use "LastToken" instead of "NumToken"

llvm-svn: 59690
2008-11-20 01:29:45 +00:00
Ted Kremenek 61915f5d4a Add (untested) implementation of PTHLexer::isNextPPTokenLParen() and PTHLexer::DiscardToEndOfLine().

Fariborz Jahanian 003e83004b More objc gc stuff. Read/Write barriers for local static/extern,
diagnostics on use of __weak attribute on fields,
Early support for read/write barriers for objc fields.

Douglas Gregor ab7897ac44 Implement the rest of C++ [over.call.object], which permits the object
being called to be converted to a reference-to-function,
pointer-to-function, or reference-to-pointer-to-function. This is done
through "surrogate" candidate functions that model the conversions
from the object to the function (reference/pointer) and the
conversions in the arguments.

Ted Kremenek 2861cf42fe Use PreprocessorLexer::getFileID() instead of Lexer::getFileLoc(). This is an intermediate step to having getCurrentLexer() return a PreprocessorLexer* instead of a Lexer*.

Ted Kremenek a2c3c8d71c Move more cases of using 'CurLexer' to 'CurPPLexer'.

Ted Kremenek 76c3441a4e When using a PTHLexer, use DiscardToEndOfLine() instead of ReadToEndOfLine().

Ted Kremenek 45245217bc - Move static function IsNonPragmaNonMacroLexer into Preprocessor.h.
- Add variants of IsNonPragmaNonMacroLexer to accept an IncludeMacroStack entry
  (simplifies some uses).
- Use IsNonPragmaNonMacroLexer in Preprocessor::LookupFile.
- Add 'FileID' to PreprocessorLexer, and have Preprocessor query this fileid
  when looking up the FileEntry for a file

Performance testing of -Eonly on Cocoa.h shows no performance regression because
of this patch.

Douglas Gregor 91cea0ad1e Support for calling overloaded function call operators (operator())
with function call syntax, e.g.,

  Functor f;
  f(x, y);

This is the easy part of handling calls to objects of class type 
(C++ [over.call.object]). The hard part (coping with conversions from
f to function pointer or reference types) will come later. Nobody uses
that stuff anyway, right? :)

Argyrios Kyrtzidis 554689a3aa Make DeclContext::getLexicalParent reuse DeclContext::getParent.
llvm-svn: 59651
2008-11-19 18:07:24 +00:00
Argyrios Kyrtzidis 0d09c4944e Take care another assert:
struct A {
  struct B;
};

struct A::B {
  void m() {} // Assertion failed: getContainingDC(DC) == CurContext && "The next DeclContext should be lexically contained in the current one."
};

Introduce DeclContext::getLexicalParent which may be different from DeclContext::getParent when nested-names are involved, e.g:

   namespace A {
      struct S;
   }
   struct A::S {}; // getParent() == namespace 'A'
                   // getLexicalParent() == translation unit

2008-11-19 17:34:06 +00:00
Douglas Gregor 40412acc02 Support overloading of the subscript operator[], including support for
built-in operator candidates. Test overloading of '&' and ','.

In C++, a comma expression is an lvalue if its right-hand
subexpression is an lvalue. Update Expr::isLvalue accordingly.

Steve Naroff 9e4ac111f0 Fix <rdar://problem/6150376> [sema] crash on invalid message send.
The core fix in Sema::ActOnClassMessage(). All the other changes have to do with passing down the SourceLocation for the receiver (to properly position the cursor when producing an error diagnostic).

llvm-svn: 59639
2008-11-19 15:54:23 +00:00
Douglas Gregor d08452f60a Added operator overloading for unary operators, post-increment, and
post-decrement, including support for generating all of the built-in
operator candidates for these operators. 

C++ and C have different rules for the arguments to the builtin unary
'+' and '-'. Implemented both variants in Sema::ActOnUnaryOp.

In C++, pre-increment and pre-decrement return lvalues. Update
Expr::isLvalue accordingly.

Argyrios Kyrtzidis 89709ac2cc 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.

2008-11-19 15:22:16 +00:00
Argyrios Kyrtzidis f5e2812e69 Remove Preprocessor::CacheTokens boolean data member. The same functionality can be provided by using Preprocessor::isBacktrackEnabled().

   write update bit-field value if caller requires it.

Chris Lattner 8d5bec4c7d implement a transparent optimization with the diagnostics stuff:
const char*'s are now not converted to std::strings when the diagnostic
is formed, we just hold onto their pointer and format as needed.

This commit makes DiagnosticClient::FormatDiagnostic even more of a 
mess, I'll fix it in the next commit.

2008-11-19 05:27:50 +00:00
Chris Lattner 3b05413e9d Switch several more Sema Diag methods over. This simplifies the
__builtin_prefetch code to only emit one diagnostic per builtin_prefetch.
While this has nothing to do with the rest of the patch, the code seemed
like overkill when I was updating it.

Douglas Gregor ca63811b39 Built-in equality and relational operators have return type "bool" in C++,
not "int".

Fix a typo in the promotion of enumeration types that was causing some
integral promotions to look like integral conversions (leading to
extra ambiguities in overload resolution).

Check for "acceptable" overloaded operators based on the types of the
arguments. This is a somewhat odd check that is specified by the
standard, but I can't see why it actually matters: the overload
candidates it suppresses don't seem like they would ever be picked as
the best candidates.
