18.1
This section contains notes that apply when the version is upgraded from an earlier version (H8S,
H8/300 Series C/C++ Compiler Package: Ver. 3.x or earlier).
18.1.1
When a program is developed with an upgraded compiler version, operation of the program may
change. When creating the program, note the following and sufficiently test your program.
1. Programs Depending on Execution Time and Timing
2. Programs Including an Expression with Two or More Side Effects
3. Programs with Overflow Results or an Illegal Operation
C/C++ language specifications do not specify the program execution time. Therefore, a
version difference in the compiler may cause operation changes due to timing lag of the
program execution time with peripherals such as the I/O, or may cause processing time
differences in asynchronous processing such as in interrupts.
Operations may change depending on the compiler version when two or more side effects are
included in one expression.
Example
a[i++]=b[i++];
f(i++, i++);
The value of the result is not guaranteed when an overflow occurs or an illegal operation is
performed. Operation of the program may change depending on the compiler version.
Example
int a, b;
x=(a*b)/10;
Guaranteed Program Operation
Notes on Version Upgrade
Section 18 Notes on Version Upgrade
/*
/*
/*
/*
Increment order of i is undefined. */
Parameter value changes according to increment order. */
This results in f(3, 4) or f(4, 3) when the value of i is 3. */
This may cause an overflow depending on the value range of
a and b. */
