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
- 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
- Functional for simple cases but there are some glaring omissions
(protocols, properties, and other language extensions).
- The code needs a fair bit of cleaning.
llvm-svn: 55108
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.
llvm-svn: 54838
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).
llvm-svn: 54833
- Add CodeGenModule::EmitTopLevelDecl which uses switch on kind
instead of ugly & slow dyn_cast chains.
- Drop some simple forwarding methods into the ObjC runtime.
- Privatize appropriate methods.
llvm-svn: 54827
- 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).
llvm-svn: 54824
- 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>
llvm-svn: 54768
ObjCProtocolDecl directly.
Implement CodeGen support for forward protocol decls (no-ops are so
nice to implement).
Also moved CGObjCRuntime.h out of CodeGenModule.h
llvm-svn: 54709
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.
llvm-svn: 54659
- Maps to LangOptions.Exceptions
- Currently always off, should autoselect based on language.
Update CodeGen to set unwind attribute on functions definitions based
on LangOptions.Exceptions.
- Still need to set attributes appropriately on calls.
llvm-svn: 54643
- Kill unnecessary #includes in .cpp files. This is an automatic
sweep so some things removed are actually used, but happen to be
included by a previous header. I tried to get rid of the obvious
examples and this was the easiest way to trim the #includes in one
fell swoop.
- We now return to regularly scheduled development.
llvm-svn: 54632
- Drop {Decl.h,DeclObjC.h,IdentifierTable.h} from Expr.h
- Moved Sema::getCurMethodDecl() out of line (dependent on
ObjCMethodDecl via dyn_cast).
llvm-svn: 54629
temporarily, I assumed GetAddrForConstantString literal was being
used consistently but it doesn't look like it is.
Factored out a CodeGenModule::getStringForStringLiteral which handles
extracting a std::string for the bytes of a StringLiteral, padded to
match the type.
Update EmitLValue to use getStringForStringLiteral, this was
previously not padding strings correctly. Good thing we only emit
strings in 4 different places!
