Has the same problems with interger overflow during compilation as described

for pjrc-8051
|
||||
Description: The Has the same problems with interger overflow during compilation
|
||||
as described for pjrc-8051. At typical cause is code like
|
||||
usleep(500*1000) which exceeds the range of a 16-bit integer
|
||||
Status: See pjrc-8051
|
||||
Priority: See pjrc-8051
|
||||
|
||||
Description: The simulated serial console (configs/z80sim/src/z80_serial.c +
|
||||
driver/serial.c) does not work. This is because there are
|
||||
no interrupts in the simulation so there is never any serial
|
||||
traffic.
|
||||
Status: Open
|
||||
Priority: Low -- the simulated console is not critical path and the designs
|
||||
to solve the problem are complex.
