;--- merge-concat-template.ll

; In an linked executable (as opposed to an object file), cgdata in __llvm_outline might be concatenated. Although this is not a typical workflow, we simply support this case to parse cgdata that is concatenated. In other words, the following two trees are encoded back-to-back in a binary format.
@.data1 = private unnamed_addr constant [72 x i8] c"<RAW_1_BYTES>", section "__DATA,__llvm_outline"
@.data2 = private unnamed_addr constant [72 x i8] c"<RAW_2_BYTES>", section "__DATA,__llvm_outline"
