Thanks for fixing this, but which mips64 triple is this?
I have tested mips64-linux-gnu among

% ls
aarch64-linux-gnu   arc-linux-gnu      bfin-elf        crx-elf
h8300-elf       ia64-linux-gnu  loongarch64-linux-gnu  m68k-linux-gnu

  nds32le-elf  or1k-linux-gnu     riscv64-linux-gnu  s390x-linux-gnu
sparc64-linux-gnu  vax-linux-gnu  xgate-elf

and they are all passing.
