Hi Zhen,
On 30f3bb09778de64 with your debug patch v2:
I've set up the qemu environment, and I'll try to solve it by tomorrow at the latest.
It seems that the problem is still strcmp(). After I commented strcmp() in
arch/m68k/include/asm/string.h, and force it to use the one in lib/string.c,
it works well.
The output i=0, because compare_symbol_name() always return zero in below loop.
'low' decreases to 0, then the loop ends.
The reason is not clear. I'm still analyzing it.
low = mid;
while (low) {
seq = get_symbol_seq(low - 1);
off = get_symbol_offset(seq);
kallsyms_expand_symbol(off, namebuf, ARRAY_SIZE(namebuf));
if (compare_symbol_name(name, namebuf))
break;
low--;
}
*start = low;
Gr{oetje,eeting}s,
Geert
