Chris Lattner d53e23328e Try to not emit the dead side of ?: if the condition is a constant.

Sebastian Redl 6f28289aca Introduce a single AST node SizeOfAlignOfExpr for all sizeof and alignof expressions, both of values and types.

Daniel Dunbar c56e67644f Add CodeGenFunction::EmitBranch. 
- Emits an unconditional branch, with extra logic to avoid generating
   spurious branches out of dummy blocks.

Chris Lattner 5b1964b5f9 short circuit && and || when possible. This substantially reduces 
the size of the -O0 output on some cases.  For example, on expr.c from
176.gcc, it shrinks the .ll file from 43164 to 42835 lines, and removed
references to two external symbols.

Daniel Dunbar 75283ff38a Centralize basic block creation in CodeGenFunction::createBasicBlock. 
- No functionality change.

Anders Carlsson 13abd7e98b Implement lowering of va_arg in clang directly. (This is 32-bit X86 only for now).

Daniel Dunbar cb4638599c Move IRBuilder type definition to common file. 
- No functionality change.

Chris Lattner 084bc32e0d make codegen reject initializes with designators, like this: 
t.c:1:13: error: cannot codegen this designators yet
int a[10] = {2, 4, [8]=9, 10};
            ^~~~~~~~~~~~~~~~~

Daniel Dunbar f2cf6d16e6 Avoid superfluous errors regarding variable-length arrays (casts).

Daniel Dunbar a799807dea Downgrade a number of FIXME asserts to ErrorUnsupported. 
- Notably VLAs

Daniel Dunbar 9e22c0d317 Add special "property reference" CodeGen::LValue type for emitting 
Objective-C property references.
 - This handles property references "more correctly" but setters still
   don't work.

Daniel Dunbar 55310df79c Initial support for Obj-C dot-syntax for getters.

Daniel Dunbar ef957f3489 Change another is-a-pointer check to check in terms of LLVM type. 
llvm-svn: 55312
 2008-08-25 10:38:11 +00:00
Daniel Dunbar 427f873196 Do is-a-pointer checks in terms of LLVM types in 
EmitScalarConversion().
 - Important for allowing Obj-C void * to id<X> casts and so on.
 - Not sure about this fix however, perhaps Type should understand
   that id is effectively a pointer type.

Argyrios Kyrtzidis ce4528f008 Add CodeGen support for CXXZeroInitValueExpr. 
llvm-svn: 55249
 2008-08-23 19:35:47 +00:00
Daniel Dunbar c8317a44cf Implement Obj-C ivar references to aggregates. 
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).

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

 2008-08-23 03:46:30 +00:00
Daniel Dunbar 66912a1a6d Move all Obj-C runtime interaction into CodeGenFunction. 
- Drop duplicate (and broken) code for sending messages.
 - Add EmitObjCProtocolExpr to CodeGenFunction.

llvm-svn: 55024
 2008-08-20 00:28:19 +00:00
Daniel Dunbar 8bc821ae7c Add CodeGen support for AddrLabelExpr in initializers. 
llvm-svn: 54837
 2008-08-16 01:41:47 +00:00
Daniel Dunbar a7c8cf6200 Change WarnUnsupported to ErrorUnsupported (in name and in practice). 
- We are beyond the point where this shows up often and when it does
   generating miscompiled files is bad.

llvm-svn: 54836
 2008-08-16 00:56:44 +00:00
Daniel Dunbar 89da6ad1db Change ObjCRuntime GenerateProtocol[Ref] methods to take 
ObjCProtocolDecl directly.

Implement CodeGen support for forward protocol decls (no-ops are so
    nice to implement).

Also moved CGObjCRuntime.h out of CodeGenModule.h

 2008-08-13 00:59:25 +00:00
Daniel Dunbar d627c85f43 Drop Sender from GenerateMessageSend* 
- Was unused and generated a unnecessary load of self
(missed file)

llvm-svn: 54668
 2008-08-12 05:40:10 +00:00
Daniel Dunbar 6630e10ccc Protocol related tweaks 
- Implement type conversion of ObjCQualifiedIdType
 - Wire @protocol(...) to GenerateProtocolRef in ScalarExprEmitter
