ubsan: csky: left shift cannot be represented in type 'int'
In the following buf is an unsigned char array, so elements are
promoted to int before arithmetic operations.
if (dis_info.info->endian == BFD_ENDIAN_BIG)
while (n--)
val |= buf[n] << (n*8);
else
for (i = 0; i < n; i++)
val |= buf[i] << (i*8);
* csky-dis.c (csky_chars_to_number): Rewrite. Avoid signed
overflow when collecting bytes of a number.
