/* 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.  */

	352	The linkers setup the required dynamic entries in the dynamic segment
	353	and the dynamic linker does the calls. This approach avoids using
	354	collect2.
	355
	356	The first hack is to implement __do_global_ctors_aux in crtbegin as
	357	it needs to be the first entry in the init array so that it is called
	358	last. HP got the order of the init array backwards. The DT_INIT_ARRAY
	359	is supposed to be executed in the same order as the addresses appear in
	360	the array. DT_FINI_ARRAY is supposed to be executed in the opposite
	361	order.
	362
25e266ae	363	The second hack is a set of plabels to implement the effect of
de419443	364	CRT_CALL_STATIC_FUNCTION. HP-UX 11 only supports DI_INIT_ARRAY and
	365	DT_FINI_ARRAY and they put the arrays in .init and .fini, rather than
	366	in .init_array and .fini_array. The standard defines for .init and
	367	.fini have the execute flag set. So, the assembler has to be hacked
	368	to munge the standard flags for these sections to make them agree
	369	with what the HP linker expects. With the GNU linker, we need to
	370	used the .init_array and .fini_array sections. So, we set up for
	371	both just in case. Once we have built the table, the linker does
	372	the rest of the work.
	373
	374	The order is significant. Placing __do_global_ctors_aux first in
	375	the list, results in it being called last. User specified initializers,
	376	either using the linker +init command or a plabel, run before the
