functions as well as to non-static data members.

Implement correct lvalue computation for member references in C++. 
Compute the result type of non-static data members of reference type properly.

uses of getName() with uses of getDeclName().  This upgrades a bunch of
diags to take DeclNames instead of std::strings.

This also tweaks a couple of diagnostics to be cleaner and changes
CheckInitializerTypes/PerformInitializationByConstructor to pass
around DeclarationNames instead of std::strings.

 - Use extra argument to EmitStoreThroughLValue to provide place to
   write update bit-field value if caller requires it.
 - This fixes several FIXMEs.

function call created in response to the use of operator syntax that
resolves to an overloaded operator in C++, e.g., "str1 +
str2" that resolves to std::operator+(str1, str2)". We now build a
CXXOperatorCallExpr in C++ when we pick an overloaded operator. (But
only for binary operators, where we actually implement overloading)

I decided *not* to refactor the current CallExpr to make it abstract
(with FunctionCallExpr and CXXOperatorCallExpr as derived
classes). Doing so would allow us to make CXXOperatorCallExpr a little
bit smaller, at the cost of making the argument and callee accessors
virtual. We won't know if this is going to be a win until we can parse
lots of C++ code to determine how much memory we'll save by making
this change vs. the performance penalty due to the extra virtual
calls.

 - Logic such as this quite possibly should be optional builder
   behavior.

Add a new expression class, ObjCSuperExpr, to handle the Objective-C 'super'. Remove ObjCThis from PredefinedExpr

llvm-svn: 58698

llvm-svn: 57745

 - Shouldn't assume predefined expr is a function printing one.
 - Uses CGM functionality to cache function names per module.

llvm-svn: 57737

 - Add CodeGenFunction::{EmitReturnOfRValue, EmitIvarOffset}
 - Factor EmitLValueForIvar out of EmitObjCIvarRefLValue.

No non-error functionality change (some unsupported errors are
degraded to asserts for the time being).

llvm-svn: 56543

Implement CodeGen support for the 'CXXConditionDeclExpr' expression node, which represents a 'condition' declaration, e.g: "if (int x=0) {...}".

llvm-svn: 56045

 - Factor out EmitFunction{Pro,Epi}log

llvm-svn: 56031

 - Add CodeGenFunction::EmitAnyExprToTemp
   o Like EmitAnyExpr, but emits aggregates to a temporary location if
     none is available. Seems like this should be simpler (even aside
     from using first class aggregates).

 - Killed CodeGenFunction::EmitCallArg (just append the pair)

 - Conversion of RValues to actual call arguments is now isolated in
   CodeGenFunction::EmitCall.

llvm-svn: 55970

  - Add CGCall.h for dealing with ABI issues related to calls.
  - Add CGFunctionInfo and CGCallInfo for capturing ABI relevant
    information about functions and calls.
  - Isolate LLVM parameter attribute handling inside CGCall.cpp

llvm-svn: 55963

e.g. "(a = b).somefield".

llvm-svn: 55758

 - Change Obj-C runtime message API, drop the ObjCMessageExpr arg in
   favor of just result type and selector. Necessary so it can be
   reused in situations where we don't want to cons up an
   ObjCMessageExpr.
 - Update aggregate binary assignment to know about special property
   ref lvalues.
 - Add CodeGenFunction::EmitCallArg overload which takes an already
   emitted rvalue.

Add CodeGenFunction::StoreComplexIntoAddr.

Disabled logic in Sema for parsing Objective-C dot-syntax that
accesses methods. This code does not search in the correct order and
the AST node has no way of properly representing its results.

Updated StmtDumper to print a bit more information about
ObjCPropertyRefExprs.

llvm-svn: 55561

 - Added CodeGenFunction::EmitCall which just takes the callee, return
   type, and a list of (Value*,QualType) pairs.
 - Added CodeGenFunction::EmitCallArg which handles emitting code for
   a call argument and turning it into an appropriate
   (Value*,QualType) pair.
 - Changed Objective-C runtime interface so that the actual emission
   of arguments for message sends is (once again) done in the code to
   emit a message send.

No intended functionality change, this is prep work for better ABI
support and for Objective-C property setter support.

llvm-svn: 55560

Objective-C property references.
 - This handles property references "more correctly" but setters still
   don't work.

llvm-svn: 55534

Add CodeGenFunction::EmitUnsupportedLValue 
 - Gives error and returns undef value.

Swap some asserts() over to using EmitUnsupportedLValue
 - Rumor has it users (and even some developers) prefer carat
   diagnostics to backtraces.
 - Works better in Release-Asserts to boot.

llvm-svn: 55328

llvm-svn: 55298

Implement Obj-C lvalue message sends (aggregate returns).

Update several places to emit more precise ErrorUnsupported warnings
  for currently unimplemented Obj-C features (main missing chunks are
  property references, Obj-C exception handling, and the for ... in
  syntax).

llvm-svn: 55234

 - Simplify the sending code a bit.

llvm-svn: 55232

 - Returns an RValue.
 - Reduced to only taking the CodeGenFunction, Expr, and Receiver.
 - Becomes responsible for emitting the arguments.

Add CodeGenFunction::EmitCallExprExt
 - Takes optional extra arguments to insert at the head of the call.
 - This allows the Obj-C runtimes to call into this and isolates the
   argument and call instruction generation code to one place. Upshot
   is that we now pass structures (more) correctly.

Also, fix one aspect of generating methods which take structure
arguments (for NeXT). This probably needs to be merged with the
SetFunctionAttributes code in CodeGenModule.cpp

llvm-svn: 55223

 - We are beyond the point where this shows up often and when it does
   generating miscompiled files is bad.

llvm-svn: 54836

 - Returns addr of constant for argument + '\0'.
 - I couldn't think of a better name.
 - Move appropriate users of GetAddrOfConstantString to this.

Rename getStringForStringLiteral to GetStringForStringLiteral.

Add GetAddrOfConstantStringFromLiteral
 - This combines GetAddrOfConstantString and
   GetStringForStringLiteral. This method can be, but is not yet, more
   efficient.

Change GetAddrOfConstantString to not add terminating '\0'
