crtbegin.asm (__do_jv_register_classes): Don't forget to preserve gp.
* config/ia64/crtbegin.asm (__do_jv_register_classes): Don't forget to preserve gp. * config/ia64/crtend.asm (__do_global_ctors_au): Ditto. * config/ia64/crtbegin.asm (__do_jv_register_classes): Add missing .prologue directive. Use .skip instead of data8 for .bss section to make Intel Assembler (ias) happy. Minor whitespace fixups. Make "nop 0" explicit in the .mib bundles and remove the unnecessary stop bits. Replace local labels with normal labels, to make ias happy. Don't register __do_global_ctors_aux here, do it in crtend.asm instead. * config/ia64/crtend.asm [HAVE_INIT_FINI_ARRAY]: Register __do_global_ctors_aux in .init_array section instead of declaring it as a hidden global.
