Hello all, I have a question about icount and tb chaining that I hope
somebody can clear up. In cpu-exec.c, when the icount_decr.u16.low
counter expires, it passes back the current tb as the next_tb and add
a jump with the least significant bits = 2. This falls through to tb
add jump, which then updates the jmp_first field of the current tb.
why is this done? Thanks -Jim
