Fariborz Jahanian 60a901621f Fixed a nasty bug which took a while to come up with a test case,
diagnose, and took even longer to fix. It has to do with rewriting of a message
receiver which is an 'ivar' reference. Fix, however, is to remove a code which
was not doing the right thing and no longer needed.

Steve Naroff c7d2df23f8 Fix two bugs with an @throw that doesn't have a statement.
- ObjCAtThrowStmt::getSourceRange() needs to check if it has a statement (and not go "boom":-)
- RewriteTest::RewriteObjCThrowStmt() needs to generate refer to the current exception.

Chris Lattner a65e1f3b31 Move promoteExprToType from being a static method in SemaExpr.cpp to being
a method named ImpCastExprToType in Sema.

Use this method to insert implicit casts for case statements from their 
operand type to the condition type of the switch.  This fixes a crash on
test/CodeGen/statements.c, reported by Eli Friedman.

Steve Naroff abefc391dd Finish up handling all permutations of "complex int" (in Sema::UsualArithmeticConversions()).
A FIXME remains to verify the conversion rules are consistent with GCC.

Thanks to Eli for the new/improved test case...

Steve Naroff 6fcfd0581d - Change Type::isComplexType() to exlude GCC's complex integer extension. In general, we will keep the lowest level Type predicates "pure" (i.e. true to the C99 spec).
- Modify Sema::UsualArithmeticConversions() to work with the new definition of Type::isComplexType().

This is a nice cleanup and also fixes a bug submitted by Eli (which I've added to the test suite).

Steve Naroff 7f988889ef Rework commit r45976, which was incorrect.
- Add Type::isComplexIntegerType(), Type::getAsComplexIntegerType().
- Don't inlude complex types with Type::isIntegerType(), which is too general.
- Use the new predicates in Sema::UsualArithmeticConversions() to recognize/convert the types.

Steve Naroff d32419de0d Record if a compound literal expression is @ file scope. This allows us to implement C99 6.5.2.5p6. This could have been done without modifying the AST (by checking the decl type and passing the info down to isContextExpr), however we concluded this is more desirable.

Steve Naroff 826e91ae04 Change Sema::CheckAddressOfOperation() to respect C99-only addressof rules.
Remove diagnostics from Sema::CheckIndirectionOperand(). C89/C99 allow dereferencing an incomplete type. clang appears to be emulating some incorrect gcc behavior (see below).

void
foo (void)
{
 struct b;
 struct b* x = 0;
 struct b* y = &*x; // gcc produces an error ("dereferencing pointer to incomplete type")
}

With this patch, the above is now allowed.

Chris Lattner 317e6ba07f Tighten up handling of __func__ and friends: it should be an array
of const char, and it should error if it occurs outside a function.

Is it valid in an objc method?  If so we should handle that too.
