[Qemu-devel] powerpc hang

[Jon Nall]

hello.
i'm pretty new to qemu and last night set out to help debug the current
ppc hang when using gcc3. trying to understand the code has left me with
a question about how op_jmp_tb_next works on powerpc. would someone
kindly walk through what should happen? i'm speficially curious about:

- how the branch in JUMP_TB gets patched if T0 == 0 in cpu_exec()
- how the tb_jmp_offset member is ultimately used

thanks!
nall.
