 2008-10-23 01:35:34 +00:00
Douglas Gregor 5c407d9a9b Add support for conversions from a pointer-to-derived to a 
pointer-to-base. Also, add overload ranking for pointer conversions
(for both pointer-to-void and derived-to-base pointer conversions).

Note that we do not yet diagnose derived-to-base pointer conversion
errors that stem from ambiguous or inacessible base classes. These
aren't handled during overload resolution; rather, when the conversion
is actually used we go ahead and diagnose the error.

Douglas Gregor 4b62ec6353 QualType::isMoreQualifiedThan and isAtLeastAsQualifiedAs assert that we 
aren't trying to compare with address-space qualifiers (for now).

Clean up handing of DeclRefExprs in Expr::isLvalue and refactor part
of the check into a static DeclCanBeLvalue.

Zhongxing Xu da84f683c8 Add test case for FuncDecl and function pointer variable. 
llvm-svn: 57979
 2008-10-22 14:39:20 +00:00
Douglas Gregor e1eb9d8cc4 Implement ranking of standard conversion sequences by their qualification 
conversions (e.g., comparing int* -> const int* against 
int* -> const volatile int*); see C++ 13.3.3.2p3 bullet 3.

Add Sema::UnwrapSimilarPointerTypes to simplify the control flow of
IsQualificationConversion and CompareQualificationConversion (and fix
the handling of the int* -> volatile int* conversion in the former).
 

llvm-svn: 57978
 2008-10-22 14:17:15 +00:00

Chris Lattner b795443082 some minor cleanups to ParseObjCTypeName: 
1. Remove a bogus assertion, clients other than sema can return a
   null pointer from actions that result in ParseTypeName returning null.
2. Remove dead RParenLoc variable.
3. Simplify control flow handling error conditions.
4. On a major failure, we should skip until ')' not until '}'.

Daniel Dunbar c13935e8be [LLVM up] Add basic -S option to clang. 
- Split backend related consumer out into Backend.cpp, replaces
   LLVMCodeGenWriter.
 - Structure follows llvm-gcc to some extent.
 - Still need to implement all the options which impact code
   generation and the optimization passes which llvm-gcc uses at
   various levels.

 2008-10-21 23:49:24 +00:00
Douglas Gregor 9a6579340f Initial step toward supporting qualification conversions (C++ 4.4). 
Changes:
  - Sema::IsQualificationConversion determines whether we have a qualification
    conversion.
  - Sema::CheckSingleAssignment constraints now follows the C++ rules in C++,
    performing an implicit conversion from the right-hand side to the type of
    the left-hand side rather than checking based on the C notion of 
    "compatibility". We now rely on the implicit-conversion code to
    determine whether the conversion can happen or
    not. Sema::TryCopyInitialization has an ugly reference-related
    hack to cope with the initialization of references, for now.
  - When building DeclRefExprs, strip away the reference type, since
    there are no expressions whose type is a reference. We'll need to
    do this throughout Sema.
  - Expr::isLvalue now permits functions to be lvalues in C++ (but not
  in C).
