OK, thanks, there are multiple branches in upstream qemu. Sorry for my original said, and I can only say: for upstream develop master branch, it does not support microblaze.
Excuse me, I does not mainly focus on only using qemu, and I also found another easier way for test microblaze toolchain (use sim of binutils). So next, I will mainly focus on sim. I also met some issues for sim, but I guess, I can analyze it, maybe also have chances to make patch for it (that is the main reason why I want to focus on it). Thanks. Send from Lenovo A788t.
