Sebastian Redl 45c2f9d320 Correct CodeGen assumption that LongTy == Int32Ty in a few places. This makes several CodeGenObjC tests pass on 64-bit by fixing assertions. This doesn't mean that the result is actually what the GNU runtime expects, though.

Chris Lattner f3d3faeca6 Rename NamedDecl::getName() to getNameAsString(). Replace a bunch of
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.

Chris Lattner 86d7d91366 Rename NamedDecl::getIdentifierName() to ::getNameAsCString() and make it
assert if the name is not an identifier.  Update callers to do the right
thing and avoid this method in unsafe cases.  This also fixes an objc
warning that was missing a space, and migrates a couple more to taking
IdentifierInfo and QualTypes instead of std::strings.

Chris Lattner e4b95698df Rename Selector::getName() to Selector::getAsString(), and add
a new NamedDecl::getAsString() method.

Change uses of Selector::getName() to just pass in a Selector 
where possible (e.g. to diagnostics) instead of going through
an std::string.

This also adds new formatters for objcinstance and objcclass
as described in the dox.

Douglas Gregor 77324f3854 Introduction the DeclarationName class, as a single, general method of
representing the names of declarations in the C family of
languages. DeclarationName is used in NamedDecl to store the name of
the declaration (naturally), and ObjCMethodDecl is now a NamedDecl.

2008-09-24 03:38:44 +00:00
Daniel Dunbar 7a95ca3197 Move FunctionType conversion into CGCall.cpp:
- Added CodeGenTypes::GetFunctionType, taking a CGFunctionInfo.
 - Updated Obj-C runtimes to use this instead of rolling the
   llvm::FunctionType by hand.
 - Killed CodeGenTypes::{ConvertReturnType, DecodeArgumentTypes}.

Add ABIArgInfo class to encapsulate ABI decision of how to lower types
to LLVM.
 - Will move to target sometime soon.

Daniel Dunbar 41cf9dedc6 Change CodeGen to emit calls using (RValue,Type) list:
- 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.

Daniel Dunbar 4b8c6db927 Add Objective-C property setter support.
- 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
2008-08-30 05:35:15 +00:00
Daniel Dunbar c722b8565c Refactor handling of calls:
- 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.

Daniel Dunbar ca8531a2d7 Fix Obj-C super sends inside class methods.
- NeXT loads the super class at runtime; this required changing the
   runtime interface to pass more information down.

Daniel Dunbar 97db84ce6d Trim CGObjCRuntime::GenerateMessageSend[Super]
- 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

Daniel Dunbar a94ecd2a0b Add NeXT runtime support for generating methods.
Change CodeGenFunction::EmitParmDecl to take either a ParmVarDecl or an
  ImplicitParamDecl.

Drop hasAggregateLLVMType from CodeGenModule.cpp (use version in
  CodeGenFunction).

Change the Objective-C method generation to use EmitParmDecl for
  implicit parameters.

Daniel Dunbar 7c6d3a7c50 Change ObjCRuntime::LookupClass -> GetClass, and now takes the
ObjCInterfaceDecl.

Change ObjCRuntime::GenerateMessageSendSuper to take the
  ObjCInterfaceDecl for the super class, instead of just its name.

Change EmitObjCMessageExpr to make the right runtime calls for super
  sends in class methods (i.e. a super send with the class object as
  the receiver).

2008-08-16 00:25:02 +00:00
Daniel Dunbar 9299250939 Change CGObjCRuntime methods to take appropriate clang Decls.
- This is in prep for implementation class support for the NeXT
   runtime, for which the existing methods don't provide enough
   information (and additionally make too many assumptions about how
   things should be emitted).

Daniel Dunbar c4baa06d15 Add GetAddrOfConstantCString method
- 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'
 - <rdar://problem/6140956>

Daniel Dunbar 89da6ad1db Change ObjCRuntime GenerateProtocol[Ref] methods to take

Daniel Dunbar 8b8683f9f6 Add ObjC constant string support for NeXT.
Changed CGObjCRuntime::GenerateConstantString interface to take
       std::string instead of char* and size.

Change ObjC functions which call on GenerateConstantString to bitcast
       result to appropriate type.

Chris Lattner 6447ed3a1f "This is a small fix for a bug where static object instances were being incorrectly generated.

Chris Lattner 091f698d29 "this patch adds code generation hooks for Objective-C constant strings. It also modifies Sema so that Objective-C constant strings are treated as untyped objects if the interface for the constant string class can not be found. This is consistent with Apple GCC. I thought it was consistent with GNU GCC, since this was causing failures when trying to compile GNUstep with (GNU) GCC, but it appears that this is not the case when attempting to produce a simple test case to demonstrate it. Possibly there is a way of making the error go away, but I haven't found out what it is yet."

Chris Lattner 7a51313d8a 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.
