uncompleted struct types. We now do what llvm-gcc does and compile
them into [i8 x 0]. If the type is later completed, we make sure that
it is appropriately cast.
We compile the terrible example to something like this now:
%struct.A = type { i32, i32, i32 }
@g = external global [0 x i8]
define void @_Z1fv() nounwind {
entry:
call void @_Z3fooP1A(%struct.A* bitcast ([0 x i8]* @g to %struct.A*))
ret void
}
declare void @_Z3fooP1A(%struct.A*)
define %struct.A* @_Z2f2v() nounwind {
entry:
ret %struct.A* getelementptr inbounds ([0 x %struct.A]* bitcast ([0 x i8]* @g to [0 x %struct.A]*), i32 0, i64 1)
}

//===----------------------------------------------------------------------===// // C Language Family Front-end //===----------------------------------------------------------------------===// Welcome to Clang. This is a compiler front-end for the C family of languages (C, C++, Objective-C, and Objective-C++) which is built as part of the LLVM compiler infrastructure project. Unlike many other compiler frontends, Clang is useful for a number of things beyond just compiling code: we intend for Clang to be host to a number of different source level tools. One example of this is the Clang Static Analyzer. If you're interested in more (including how to build Clang) it is best to read the relevant web sites. Here are some pointers: Information on Clang: http://clang.llvm.org/ Building and using Clang: http://clang.llvm.org/get_started.html Clang Static Analyzer: http://clang-analyzer.llvm.org/ Information on the LLVM project: http://llvm.org/ If you have questions or comments about Clang, a great place to discuss them is on the Clang development mailing list: http://lists.cs.uiuc.edu/mailman/listinfo/cfe-dev If you find a bug in Clang, please file it in the LLVM bug tracker: http://llvm.org/bugs/
