Code:

        use32
        mov     eax,cr8         ;\ fasm 1.73.22 generates the same code
        mov     eax,cr9         ;/
        mov     cr8,eax         ;\ same as above
        mov     cr9,eax         ;/

Probably CR9 should not be allowed at all here. Looking at recent AMD manuals I see that only CR8 has ever been documented for F0-prefixed variant.
