Hello,
while waiting for my msp430x149 device I did some tests of my code with
msp430simu. When running the following code:
int64_t a = 1152921504606846976LL; // 2^60
int32_t b = 1073741824L; // 2^30
int32_t c = (int32_t)(a / b);
the simulation stops with the following error message:
Traceback (most recent call last):
File "./testing.py", line 107, in ?
msp.start()
File "./testing.py", line 88, in start
self.step()
File "./core.py", line 1129, in step

File "./core.py", line 817, in execRRC
arg.set(r)
File "./core.py", line 650, in set
raise "not possible as destination"
not possible as destination
My question to the mspgcc-experts:
Did I make something wrong, is it a simulator problem or is the msp430x149 or
the mspgcc not able to do this kind of calculations?
thats a simulator problem. i have not worked on it for quiet some time
and i suspect that there are some smaller bugs in the instruction
decoding (regarding the number of cycles). and it should not stop
simulating anyway as the real taget cannot be stopped neither.
however its not related to the x149 device because all the MSP430x1xx
and MSP430x4xx devices have the same instruction set.
note that msp430-gdb also includes a simu. select the remote "target sim".
