+   *  CodePosition indicates the ability of the generated output to be
+   *  loaded at different addresses. If the output can be loaded at different
+   *  addresses, we say the output is position independent. Shared libraries
+   *  and position-independent executable programs (PIE) are in this category.
+   *  ::Independent indicates the output is position independent.
+   *  If a executable program can not be loaded at arbitrary addresses, but it
+   *  can call outside functions, we say the program is dynamic dependent on
+   *  the address to be loaded. ::DynamicDependent indicates the output is not
+   *  only a executable program, but also dynamic dependent. In general,
+   *  executable programs are dynamic dependent.
+   *  If a executable program can not be loaded at different addresses, and
+   *  only call inner functions, then we say the program is static dependent on
+   *  its loaded address. ::StaticDependent is used to indicate this kind of
+   *  output.
