If this is true and data memory (a.k.a. scratchpad
memory, 0x00-0x80) overlaps code memory then using
registers r0-r7 destroys the reset-vector and the first
interrupt-vector(s). And using bits in the bit-
addressable memory (0x20-0x30) destroys other interrupt-
vectors. I very much doubt this is the case, but I agree
the datasheet is not clear about this.
I still believe you do not need --no-pack-iram nor --
data-loc.
