--- Comment #4 from Arseny Vakhrushev <neoxic at icloud dot com> ---
Thanks a lot, Andrew! Totally my bad. Well, comparison seems to work too:
extern char _src[], _dst[], _end[]; // Defined by the linker
int main(void) {
char *src = &_src[0];
char *dst = &_dst[0];
char *end = &_end[0];
while (src < end) *dst++ = *src++;
return 0;
}
Are the asm("" : "+r" (p)) statements strictly needed?
