Asking for ppc32 plt call stubs to be aligned at 32 byte boundaries didn't quite work. For ld.bfd they were spaced 32 bytes apart, but only started on a 16 byte boundary. ld.gold also didn't get it right. Finding that bug made me check over the ppc64 plt stub alignment, where I found that negative values for alignment (meaning align to minimize boundary crossing) were not accepted. Since no one has complained about that, I guess I could have removed the feature from ld.bfd documentation, but I've opted instead to correct the code. I've also added an optional alignment paramenter for ppc32 --plt-align, for some consistency with gold and ppc64 ld.bfd. bfd/ * elf32-ppc.c (ppc_elf_create_glink): Correct alignment of .glink. * elf64-ppc.c (ppc64_elf_size_stubs): Handle negative plt_stub_align. (ppc64_elf_build_stubs): Likewise. gold/ * powerpc.cc (param_plt_align): New function supplying default --plt-align values. Use it.. (Stub_table::plt_call_align): ..here, and.. (Output_data_glink::global_entry_align): ..here. (Stub_table::stub_align): Correct 32-bit minimum alignment. ld/ * emultempl/ppc32elf.em: Support optional --plt-align arg. * emultempl/ppc64elf.em: Support negative --plt-align arg.
