[Bug 1877706] Re: [Feature request] qemu does not support for Octeon MIPS64 on X86

Hi, Lu.

Where can I download Octeon toolchain you used?

I want to try it by myself.

Title:
   [Feature request] qemu does not support for Octeon MIPS64 on X86

Status in QEMU:
  New

Bug description:
  Description of problem:

  I use mips64-octeon-linux-gnu-gcc cross toolchain on X86,and generate
  binary file.

  > mips64-octeon-linux-gnu-gcc hello.c -static
  > file a.out
  > a.out: ELF 32-bit MSB executable, MIPS, N32 MIPS64 rel2 version 1 (SYSV), 
statically linked, for GNU/Linux 2.4.0, not stripped

  I execute it with mips64-linux-user mode in qemu, it is invalid.

  > ./qemu-5.0.0/mips64-linux-user/qemu-mips64 a.out
  > a.out: Invalid ELF image for this architecture

  when I choose mips-linux-user mode, it regards as illegal instruction.

  > ./qemu-5.0.0/mips-linux-user/qemu-mips a.out
  > qemu: uncaught target signal 4 (Illegal instruction) - core dumped
  > Illegal instruction (core dumped)

  I would like to know, is this due to my problem or does qemu not
  support Octeon MIPS64 on X86?

  if qemu has supported Octeon MIPS64 on X86, how can I emulate it.
