Hello folks,

recently there was some refactoring work on the 32-bit emulate_instruction to
fix bug 44636

0x0f 0x20-0x2f

20: MOV Rd,Cd
21: MOV Rd,Dd
22: MOV Cd,Rd
23: MOV Dd,Rd

("ntoskrnl.exe: More general implementation of the CRn and DRn registers.")

https://source.winehq.org/git/wine.git/commitdiff/0cbb5d0a146ebb2a80712cab7e2c1530edad9a6d
("ntoskrnl.exe: Add a helper function for accessing registers.")

Sadly the 64-bit emulate_instruction lacks it entirely.

$ wine --version
