- New rbit* instruction, used for reversing bits.
- new popcnt* instruction, used to count set bits in a word.
- new lrot* and rrot* instructions, used to rotate bits.
- new ext*, ext*_u and dep* instructions, used to extract and deposit bits, using a pattern compatible with C bit fields.
- New qlsh*, qlsh*_u, qrsh* and qrsh*_u instructions, used to as normal shifts, but that also save overflow or underflow bits in a second output register.
- New unld*, unld*_u, unst*, unld*_x and unst*_x instructions, used to read or write unaligned memory.
- New mov*_f_w, mov*_w_f, mov*_d_w, mov*_w_d, mov*_d_ww and mov*_ww_d instructions, used to move values from/to gpr from/to fpr registers without using memory (if supported by the cpu).
