Check two registers for equal/not equal on DLX program

DLX provides two instructions for comparing numbers:

1. seq (set if equal)
2. sne (set if not equal).

Seq instruction example:

Seq result register,compare1 register,compare2 register
Result register will be 1 if the registers are equal otherwise 0

Use branch true (bt) or branch false (bf) to compare result register

1:  seq r1,r2,r4 ;Checks if r2=r4  
2:  bt r1,L1 ; if true (Branch true ) Jump to L1  
3:  <OtherStatements> ;If false execute this  
4:  jr r31 ;end program  
5:  L1 ;Jump to here if condition fails  
6:  jr r31 ;end program  

Sne instruction example: 
Sne result register,compare1 register,compare2 register
Result register will be 1 if the registers are not equal otherwise 0
Use branch true (bt) or branch false (bf) to compare result register

1:  sne r1,r2,r4 ;Checks if r2=!r4  
2:  bt r1,L1 ; if true (Branch true ) Jump to L1  
3:  <OtherStatements> ;If false execute this  
4:  jr r31 ;end program  
5:  L1 ;Jump to here if condition fails  
6:  jr r31 ;end program
