Hi, I'm fixing the syscall problem for linux-user/unicore32 in qemu. I write a "hello world" program to test linux-user/unicore32 in qemu 2.7 with toolchain of uc4-1.0.5(you can download it through http://mprc.pku.edu.cn/~guanxuetao/linux/uc4-1.0.5-hard.tgz). And it's just OK. It goes well in the old version qemu that we using, also.
Can you discribe the bug more detailed? Or how do you find that the unicore32 don't use the real syscall numbers? How should test this? By Linux Test Project? It's not necessary to do all test in LTP.
