Hi everybody, We get some issues with reverse execution caused by indeterminism. Something catched our attention: static void icount_warp_rt(void *opaque), cpus.c:276 We have the feeling that icount is synchronized with rt_clock, is that possible? According to this Paolo's series this must be called when the cpus are sleeping, but I saw this called frequently during the execution, is that the expected behaviour? If not what's the best way to fix that? Thanks, Fred |
