The gotha() relocation mnemonic will be outputted by OpenRISC GCC when using the -mcmodel=large option. This relocation is used along with got() to generate 32-bit GOT offsets. This increases the previous GOT offset limit from the previous 16-bit (64K) limit. This is needed on large binaries where the GOT grows larger than 64k. bfd/ChangeLog: PR 21464 * bfd-in2.h: Add BFD_RELOC_OR1K_GOT_AHI16 relocation. * elf32-or1k.c (or1k_elf_howto_table, or1k_reloc_map): Likewise. (or1k_final_link_relocate, or1k_elf_relocate_section, or1k_elf_check_relocs): Likewise. * libbfd.h (bfd_reloc_code_real_names): Likewise. * reloc.c: Likewise. cpu/ChangeLog: PR 21464 * or1k.opc (or1k_imm16_relocs, parse_reloc): Define parse logic for gotha() relocation. include/ChangeLog: PR 21464 * elf/or1k.h (elf_or1k_reloc_type): Define R_OR1K_GOT_AHI16 number. opcodes/ChangeLog: PR 21464 * or1k-asm.c: Regenerate. gas/ChangeLog: PR 21464 * testsuite/gas/or1k/reloc-1.s: Add test for new relocation. * testsuite/gas/or1k/reloc-1.d: Add test result for new relocation.
