MOVEFROMCREG

Retrieves data from CBUS register. Register address is encoded as CONST.0E+#imm. It seems that src1 is used for address. p6dis/p6as handle this automatically (p6dis decodes to CRBUS register names)

Modifiers

On Core2 there is HI/LO modifier, LO modifier accesses crbus 0..1ff, HI modifier is for 200..3ff.

Typical usage

BX =           MOVEFROMCREG   (CONST_0E+042  , CONST_0E+042  )
EAX =          MOVEFROMCREG   (CONST_0E+161  , CONST_0E+161  )
EAX =          MOVEFROMCREG   (TMP7          , CONST_0       , U2_20)
R34 =          MOVEFROMCREG   (CR_SCP8       , R35           )

On core2:

.org 0x7f80
RBX =    MOVEFROMCREG.LO(RAX, RAX      /* s timhle to nefunguje: U4:0000 0000 0010 0000 0000 0000 0000 0000 */)
RCX =    MOVEFROMCREG.HI(RAX, RAX       /* s timhle to nefunguje: U4:0000 0000 0010 0000 0000 0000 0000 0000 */)

EOM MOVE.DSZ32     (CONST  , CONST_0       , U4.00040000)
EOM  MOVE.DSZ32     (CONST  , CONST_0       , U4.00040000)
