(4) Overflow operations and division by zero
When the cpuexpand option is specified, no overflow or underflow errors are output.
Example:
[1] b=a;
[2] while(1)a;
No error message is output even if there is an overflow operation or division by zero. However,
in an operation on a single constant or a pair of constants, if there is an overflow or division by
zero, an error message is output at compile time. In H8SX, however, the compiler might not
detect division by zero.
Example:
void main(void)
{
}
b=a;
/* Compiler error message is output in response to overflow or
/* division by zero for an operation on a constant or pair of constants
/* No error message is output in response to an overflow at runtime
int ia;
int ib;
float fa;
float fb;
ib=32767;
fb=3.4e+38f;
fb=fb+3.4e+38f;
ib=ib+32767;
fa=1.0/0.0;
ia=99999999999;
fa=3.5e+40f
ia=1/0;
/* The expression on the first line may be deleted as redundant code */
/* The reference of the variable a and loop statement may be */
/* deleted as redundant */
/* (E) Detects division by zero excluding H8SX and H8S
/* Overflow in floating-point operation result ignored */
/* Overflow in operation result ignored
/* (W) Detects overflow of constant
/* (W) Detects overflow of floating-point operation */
/* (W) Detects floating-point division by zero
/* excluding H8SX and H8S
