-/* We use DTOR_LIST_BEGIN to carry a bunch of hacks to allow us to use
-   the init and fini array sections with both the HP and GNU linkers.
-   The linkers setup the required dynamic entries in the dynamic segment
-   and the dynamic linker does the calls.  This approach avoids using
-   collect2.
-
-   The first hack is to implement __do_global_ctors_aux in crtbegin as
-   it needs to be the first entry in the init array so that it is called
-   last.  HP got the order of the init array backwards.  The DT_INIT_ARRAY
-   is supposed to be executed in the same order as the addresses appear in
-   the array.  DT_FINI_ARRAY is supposed to be executed in the opposite
-   order.
-
-   The second hack is a set of plabels to implement the effect of
-   CRT_CALL_STATIC_FUNCTION.  HP-UX 11 only supports DI_INIT_ARRAY and
-   DT_FINI_ARRAY and they put the arrays in .init and .fini, rather than
-   in .init_array and .fini_array.  The standard defines for .init and
-   .fini have the execute flag set.  So, the assembler has to be hacked
-   to munge the standard flags for these sections to make them agree
-   with what the HP linker expects.  With the GNU linker, we need to
-   used the .init_array and .fini_array sections.  So, we set up for
-   both just in case.  Once we have built the table, the linker does
-   the rest of the work.
-
-   The order is significant.  Placing __do_global_ctors_aux first in
-   the list, results in it being called last.  User specified initializers,
-   either using the linker +init command or a plabel, run before the
-   initializers specified here.  */
