Subject: R_MIP16_GOT16 and R_MICROMIPS_GOT16
Date: Tue, 2 Apr 2024 11:37:35 +1030 [thread overview]
Message-ID: <ZgtaVzrSeIqRopT4@squeak.grove.modra.org> (raw)
In-Reply-To: <ZgtaG0H6RkTQlPtf@squeak.grove.modra.org>
In rela howtos these relocations should not be using
_bfd_mips_elf_got16_reloc. That special function is for extracting
addends from section contents, and only for that (ie. it doesn't
subtract gp). Make these rela howtos like the corresponding
R_MIPS_GOT16 rela howto.
* elf64-mips.c (mips16_elf64_howto_table_rela <R_MIPS16_GOT16>):
Use _bfd_mips_elf_generic_reloc.
(micromips_elf64_howto_table_rela <R_MICROMIPS_GOT16>): Likewise.
* elfn32-mips.c (elf_mips16_howto_table_rela <R_MIPS16_GOT16>):
Likewise.
(elf_micromips_howto_table_rela <R_MICROMIPS_GOT16>): Likewise.
OK?
