+Built from the following source:
+void f1();
+__attribute__((always_inline)) inline void f2() { f1(); }
+void f3() { f2(); }
+
+Compiled to assembly with clang, modified the skeleton CU to remove the
+high/low pc (& update the CU length field and abbrev to match) & then
+compile/objcopy to make the .o and .dwo.
