gas * config/tc-rl78.h (TC_LINKRELAX_FIXUP): Define. (TC_FORCE_RELOCATION_SUB_SAME): Define. (DWARF2_USE_FIXED_ADVANCE_PC): Define. * gas/lns/lns.exp: Add RL78 to list of targets using DW_LNS_fixed_advance_pc. bfd * elf32-rl78.c (RL78_OP_REL): New macro. (rl78_elf_howto_table): Use it for complex relocs. (get_symbol_value): Handle the cases when the info or status arguments are NULL. (get_romstart): Cache the status returned by get_symbol_value. (get_ramstart): Likewise. (RL78_STACK_PUSH): Generate an error message if the stack overflows. (RL78_STACK_POP): Likewise for underflows. (rl78_compute_complex_reloc): New function. Contains the basic processing code for all RL78 complex relocs. (rl78_special_reloc): New function. Provides special reloc handling for complex relocs. (rl78_elf_relocate_section): Use rl78_compute_complex_reloc. (rl78_offset_for_reloc): Likewise. binutils* readelf.c (target_specific_reloc_handling): Add code to handle RL78 complex relocs.
