We can't use the output section size to copy input section since --interleave will shrink the output section. Instead, we change bfd_convert_section_contents to return the updated input section size.

2015-09-01ppc64 out-of-line register save/restore functionsAlan Modra1-0/+21
Don't emit long branch or plt branch stubs to save/restore functions. Copy them instead. The problem is that plt branch stubs currently trash r12, one of the parameters to some of the save/restore functions, and there is no free register available to use instead of r12. 6f20ed8a is prerequisite for this patch. PR 18878 * elf64-ppc.c (ARRAY_SIZE): Define. Use throughout. (enum ppc_stub_type): Add ppc_stub_save_res. (struct map_stub): Add "next" and "needs_save_res".

2015-08-31Optimise PowerPC64 r2 adjusting stubsAlan Modra1-0/+8
Sometimes these stubs don't need to change the low 16-bits of r2, so in that case omit a useless addi r2,r2,0 insn. Also, change the get_r2off error return from 0 to -1 since 0 is a valid return for ELFv2 -R objects. * elf64-ppc.c (get_r2off): Return -1 on error. (ppc_build_one_stub): Adjust for get_r2off change.

Two organizational changes to the array of additional info kept for sections. 1) Move group info into a per-group allocated struct, in preparation for future changes that need per-group accounting. 2) Expand the array to include output sections, which simplifies sizing and removes the need for a separate output section array. * section.c (section_id): Make file scope.
