 101         at the same time as setting h.  Use elf32_arm_allocate_local_sym_info
 102         to allocate local symbol information.  Treat R_ARM_REL32 and

 114         to allocate .plt and .(i)got.plt entries.  Detect which .got
 115         entries will need R_ARM_IRELATIVE relocations and use
 116         elf32_arm_allocate_irelocs to allocate them.  Likewise other

 126         STT_GNU_IFUNC symbols at an .iplt entry if non-call relocations
 127         resolve to it.
 128         (elf32_arm_output_plt_map_1): New function, split out from
