338 the init and fini array sections with both the HP and GNU linkers. | |
339 The linkers setup the required dynamic entries in the dynamic segment | |
340 and the dynamic linker does the calls. This approach avoids using | |
341 collect2. | |
342 | |
343 The first hack is to implement __do_global_ctors_aux in crtbegin as | |
344 it needs to be the first entry in the init array so that it is called | |
345 last. HP got the order of the init array backwards. The DT_INIT_ARRAY | |
346 is supposed to be executed in the same order as the addresses appear in | |
347 the array. DT_FINI_ARRAY is supposed to be executed in the opposite | |
348 order. | |
349 | |
350 The second hack is a set of plabels to implement the effect of | |
351 CRT_CALL_STATIC_FUNCTION. HP-UX 11 only supports DI_INIT_ARRAY and | |
352 DT_FINI_ARRAY and they put the arrays in .init and .fini, rather than | |
353 in .init_array and .fini_array. The standard defines for .init and | |
354 .fini have the execute flag set. So, the assembler has to be hacked | |
355 to munge the standard flags for these sections to make them agree | |
356 with what the HP linker expects. With the GNU linker, we need to | |
357 used the .init_array and .fini_array sections. So, we set up for | |
358 both just in case. Once we have built the table, the linker does | |
359 the rest of the work. | |
360 | |
361 The order is significant. Placing __do_global_ctors_aux first in | |
362 the list, results in it being called last. User specified initializers, | |
363 either using the linker +init command or a plabel, run before the | |
364 initializers specified here. */ | |
