Subject: * config/tc-mips.c (s_gpdword): New function.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=10181a0dce686bb01df699b50899dde238245c2d;p=binutils-gdb.git

* config/tc-mips.c (s_gpdword): New function.
(mips_pseudo_table): Add .gpdword.
(mips_need_elf_addend_fixup): never for NEWABI.
(md_apply_fix3): Don't mark BFD_RELOC64 after GPREL16 or
GPREL32 as done.
(s_cpadd): Generate .cpadd on NEWABI.
