If I compile the following code (SDCC 2.7.0):
------------------------------------------------
void func(void)
{
int timeout;
return;
timeout = 0xFFFF;
while (timeout--);
}
------------------------------------------------
SDCC produces the following warnings:
"src/test.c:8: warning 84: 'auto' variable 'timeout' may be used before
initialization
src/test.c:8: warning 84: 'auto' variable 'timeout' may be used before
initialization
src/test.c:8: warning 84: 'auto' variable 'timeout' may be used before
initialization"
Any idea why?
And before someone says "Don't call 'return' there!" - this scenario
happens when a macro is set to "return" to eliminate the 2nd half of a
function.
Thanks,
Mary-Ann
