llvm dev - Nov 2011 - [LLVMdev] LLVM ERROR: Cannot select: intrinsic %llvm.annotation

I'm trying to insert some annotations using the @llvm.annotation.i32
intrinsic. When I compile the file with llc, it gives me the error "LLVM
ERROR: Cannot select: intrinsic %llvm.annotation". My IR file looks like
this:

$ cat test.ll
@.str = private unnamed_addr constant [6 x i8] c"Hello\00"
declare i32 @llvm.annotation.i32(i32, i8* , i8*, i32)

define i32 @main(i32 %argc, i8** %argv) nounwind ssp {
  %1 = call i32 @llvm.annotation.i32(
     i32 0, 
     i8* getelementptr inbounds ([6 x i8]* @.str, i32 0, i32 0), 
     i8* getelementptr inbounds ([6 x i8]* @.str, i32 0, i32 0), 
     i32 0
  )
  ret i32 0
}

$ llc test.ll
LLVM ERROR: Cannot select: intrinsic %llvm.annotation


Is this a problem with LLVM, or am I doing something wrong? I'm seeing this
on the release_30 branch.
