(b_out_get_reloc_upper_bound): For BSS section, just return 0.
(aligncode): When shrinking, the addend should be set to the current offset in the section plus the number of bytes of padding that will actually be retained. (b_out_relax_section): If a section contains no relocations, don't bother processing them. (b_out_get_relocated_section_contents): Set reloc_done. Assert that bfd_get_section_contents returns true. Check that relocs are properly ordered. (b_out_get_relocated_section_contents, case ALIGNDONE): Assert that reloc's addend falls between the current source offset and the raw size of the input section. Changed some indentation, deleted trailing whitespace, fixed some comments, removed some "#if 1" lines. (output_addr): New macro. (calljx_callback, callj_callback, get_value, abs32code, aligncode, b_out_get_relocated_section_contents): Use it for readability.
