No, that wasn't it. This is it:
opcode_t *ne_nc_ic(opcode_t cur_opcode[], struct Parrot_Interp *interpreter) {
IV return_offset = 5;
if (NUM_REG(cur_opcode[1]) != *(NV *)&cur_opcode[2]) {
return cur_opcode + cur_opcode[4];
Now, this (and similar code) assumes that
sizeof(NV) == 2*sizeof(opcode_t)
and hence that the NV occupies cur_opcode[2] and cur_opcode[3] and the next
thing is in cur_opcode[4]. If sizeof(NV) == sizeof(opcode_t), then the next
thing is in cur_opcode[3].
Do I have to say
return cur_opcode + *(opcode_t*)(&cur_opcode[2] + sizeof(NV));
or is there a saner way to do it?
