## cmovCC - conditional move

    if ( CC ) dest = source

The cmovCC instruction moves the source value (second operand) to the destination register if the specified condition is true. The source can be either a register or memory location. This can be very efficient by avoiding branching for simple conditional operations.

            cmovc       ; carry                  CF=1
            cmove       ; equal                  ZF=1
            cmovg       ; greater then           ZF=0 and SF=OF
            cmovge      ; greater than or equal  SF=OF
            cmovl       ; less than              SF!=OF
            cmovle      ; less than or equal     ZF=1 or SF!=OF
            cmovo       ; overflow               OF=1
            cmovp       ; parity                 PF=1
            cmovpe      ; parity even            PF=1
            cmovpo      ; parity odd             PF=0
            cmovs       ; sign                   SF=1
            cmovz       ; zero                   ZF=1

The patterns below are used after a floating point comparison.

            cmova       ; above                  CF=0 and ZF=0
            cmovae      ; above or equal         CF=0
            cmovb       ; below                  CF=1
            cmovbe      ; below or equal         CF=1 or ZF=1

In addition to the previous patterns you can place an "n" after "cmov" to get an instruction where the condition must be false. An example is "cmovng" which means "conditional move if not greater than".

            cmovg       rax, r9         ; mov r9 to rax if result was greater
            cmovl       rax, r9         ; mov r9 to rax if result was less than
            cmovz       ax, [x]         ; mov variable x to ax if result was 0
