* po/ld.pot: Regenerate.
ppc476 icache bug workaround This implements a work-around for an icache bug on 476 that can cause execution of stale instructions when control falls through from one page to the next. The idea is to prevent such fall-through by replacing the last instruction on a page with a branch to a patch area containing the instruction, then branch to the next page. The patch also fixes a number of bugs in the existing support for long branch trampolines. bfd/ * elf32-ppc.c (struct ppc_elf_link_hash_table): Add params. Delete emit_stub_syms, no_tls_get_addr_opt.

* ldlang.c (print_assignment): Don't set expld.assign_name to dot.
Make assignments to dot keep an empty output section. An assignment to dot in an output section that allocates space of course keeps the output section. Here, I'm changing the behaviour for assignments that don't allocate space. The idea is not so much to allow people to force output of an empty section with ". = .", but to fix cases where an otherwise empty section has padding added by an alignment expression that changes with relaxation or .eh_frame editing. Such a section might have zero size before relaxation and so be stripped incorrectly. ld/ * ld.texinfo (Output Section Discarding): Mention assigning to dot as a way of keeping otherwise empty sections. * ldexp.c (is_dot, is_value, is_sym_value, is_dot_ne_0, is_dot_plus_0, is_align_conditional): New predicates.
