Ah, sorry for my mistake. I would like to make both the value
pointed by the pointers and the pointers itself read-only.
Thus the right way of the patch should be;
- print "const insn_attr_t const *inat_escape_tables[INAT_ESC_MAX + 1]" \
+ print "const insn_attr_t * const inat_escape_tables[INAT_ESC_MAX + 1]" \
Cong, could you update your patch? then I can Ack that.
Thank you,
