* elf32-hppa.c (hppa_elf_reloc): Remove DEFUN crud. Remove code
which is either commented out or ifdef'd out. Add, update and clean comments. Fix various indention and spacing problems. Handle problems related to using "ble" to jump to a stub rather than "bl" (%r31 is trashed by "ble", but not by "bl"). (NEW_INSTRUCTION): Put inside curly braces. (CURRENT_STUB_OFFSET): Fix indention problems. (hppa_elf_build_arg_reloc_stub): Fix indention and spacing problems. Add, update and clean comments. Handle "ble" %r31 lossage problems. (hppa_elf_build_long_branch_stub): Likewise. (hppa_look_for_stubs_in_section): Likewise. (hppa_elf_stub_check): Remove obsolete function. * hppa_stubs.h: Add new instructions to deal with %r31 lossage problems. Delete unused instructions.
