All the HI16 reloc howtos should have a rightshift of 16, and all the LO16 relocs shouldn't complain on overflow. This was correct for R_MIPS_LO16 and R_MIPS_LO16 (at least on the howto_table_rel entries), and corresponding MIPS16, MICROMIPS and MIPS64 relocs, but not on many other HI16 and LO16 relocs. While we're at it, fix the HIGHER and HIGHEST rightshift too. These changes are necessary to support addends outside the range [0,32767] when those addends are stored in section contents. Note that some of the reloc howtos changed here will always have zero addends (GOT_HI16, CALL_HI16). Those don't really need changing, but use what is clearly correct for hi16 relocs anyway. PR 19977 * elf32-mips.c: Correct rightshift for HI16, HIGHER and HIGHEST reloc howtos. Correct complain_on_overflow for LO16 relocs. * elf64-mips.c: Likewise. * elfn32-mips.c: Likewise.
