2011-02-14opcodes: blackfin: catch invalid loopsetup insnsMike Frysinger2-0/+8
The LoopSetup insn is only valid when the reg field is 0-7, so don't go decoding it incorrectly when reg is 8-15. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-02-14sim: punt zfree()Mike Frysinger46-125/+185
The sim keeps track of which allocations are zero-ed internally (via zalloc) and then calls a helper "zfree" function rather than "free". But this "zfree" function simply calls "free" itself. Since I can see no point in this and it is simply useless overhead, punt it. The only real change is in hw-alloc.c where we remove the zalloc_p tracking, and sim-utils.c where zfree is delete. The rest of the changes are a simple `sed` from "zfree" to "free". Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-02-14sim: change to 64bit time keeping to avoid 32bit overflowsMike Frysinger2-1/+5
The sim-events code jumps through some hoops to avoid using 64bit math to manage the current time. One fundamental assumption here is that by constantly scheduling the sim poll event a short time into the future, the 64bit difference will always fall into a signed 32bit value. This does work most of the time, except for when processing the sim poll event itself. Normally, sim_events_process() will dequeue the sim poll event, update the current time (time_from_event) according to the next pending event, process the sim poll event (which will then requeue the sim poll event), and then continue on. The problem here of course is that the current time is updated in that small window before the sim poll event gets a chance to reschedule itself. So if the 64bit difference between the current time and the next event does not fit into the signed 32bit value, time_from_event overflows, and the internal assert at the end of update_time_from_event() triggers. Since attempts at tweaking sim_events_process() logic introduced other subtle bugs (due to tangled assumptions between most pieces of the sim time keeping code), change the time_from_event to a real 64bit value. Tests on my system between a 32bit ELF and a 64bit ELF show no practical difference (it's all lost in the system noise). Basically, I booted a Linux kernel to userspace and then paniced it; this gave me a constant sample size of about 18 million insns. This was noticed when simulating Blackfin Das U-Boot. The simulated core timer is given the max unsigned timeout value possible on a 32bit processor (0xffffffff). This timeout value is used directly to schedule a hw event in the sim future (the IRQ firing). Once the sim poll event is kicked off, the next pending event is the core timer event which is more than 2^31 ticks in the future, and the sim aborts with: sim-events.c:435: assertion failed - current_time == sim_events_time (sd) Signed-off-by: Mike Frysinger <vapier@gentoo.org>

When assigning to a register half, the mac0 part of the mult insn was not decoding properly. It would always show a full dreg instead of the dreg low half.
