Hi,

void foo(unsigned char count) {
while(count--) {
/* do something here */
}
}

I compiled this on the Keil C251 V3.2 C compiler and it compiled the wrong code. I looked at the assembler output and at the beginning of the loop, it cleared count to 0 so that the loop never gets executed. Is what I did at the while-statement violated some ANSI no-nos or something?

This,
while(count) {
count--;
/* do something here */
}
however, compiled the correct code.
