Hi all.
I'm trying to port some pre-existing code to sdcc for 8051. In some files,
the original code uses gcc-style void * arithmetic, similar to this:
static unsigned short foo[15];
void funct() {
void * ptr;
ptr = foo; /* ptr is X:0xe01a */
/* do something */
ptr = (void *)foo + 1; /* ptr is still X:0xe01a */
}
Please correct me if I'm wrong but I would expect this code to cause warning
178: size of void is zero. Correct?
sdcc doesn't produce a warning, while gcc -Wpointer-arith does.
Needless to say, the code does not achieve what the developer originally
intended, which makes things hard for me to debug. So my question here is,
is there a way to turn on a warning for this scenario?
Thanks for any tips all.
Regards
geo
