Compile 64bit binary for Octeon with Octeon instructions `mips64-octeon-linux-gnu-gcc -o hello hello.c` 2. Run with `qemu-mips64` `qemu-mips64 -cpu Octeon68XX hello` 3. Get the output below: ``` qemu: uncaught target signal 4 (Illegal instruction) - core dumped Illegal instruction ``` Additional information: I have a patch for this that I will be submitting to trivial-patches. This is not enough to emulate Octeon specific binaries alone. For small binaries mapping the `CVMSEG_LM = 0xFFFFFFFFFFFF8000 - 0xFFFFFFFFFFFF9FFF` to empty RAM and using this patch is enough. There are additional support issues for `N32` binaries that will require a separate issue. [hello](/uploads/d8b5e631508fd232b4a7b3a40f7e08f6/hello)
