+ 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 stubs for __cxa_finalize and _Jv_RegisterClasses.
+ The HP implementation of undefined weak symbols is broken. The linker
+ and dynamic loader both search for undefined weak symbols contrary the
+ generic System V ABI. An undefined weak symbol should resolve to a
+ value of 0 rather than causing an error. The prototypes for
+ __cxa_finalize and _Jv_RegisterClasses in crtstuff.c are weak when
+ weak is supported (GNU as), so in theory a strong define should override
+ the stub functions provided here.
+
+ The final 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. */
