# HEAD: e86c2c8b9380440bbe761b8e2f63ab6b04a45ac2 x86/umip: Add emulation (spoofing) for UMIP covered instructions in 64-bit processes as well
The changes in this cycle were:
- Add UMIP emulation/spoofing for 64-bit processes as well, because of
Wine based gaming.
- Clean up symbols/labels in low level asm code
- Add an assembly optimized mul_u64_u32_div() implementation on x86-64.
Thanks,
Ingo
