The RV$64$I model of RISC$-$V has $64-$bit registers, and allows for lb$,$ Ih$,$ Is to perform $64-$bit sign$-$extension. Instruction Id does a load double of $8-$bytes. Make sure you take endianness into account.

So$,$ given this code:

data

lab$1$: $.$dword $0$xF$00$FFF$0000038021$

$.$text

li t$3,0$xA$5$A$5$A$5$A$5$A$5$A$5$A$5$

lat$4,$ lab$1$

Ih t$3,0($t$4)$

Please indicate the correct value of $t3$ after executing the code shown above:

$0$xFFFFFFFFFFFFF$8001$

$0$x$0180$A$5$A$5$A$5$A$5$A$5$A$5$

$0$xA$5$A$5$A$5$A$500038001$

$0$x$8001$A$5$A$5$A$5$A$5$A$5$A$5$

$0$xA$5$A$5$A$5$A$5$A$5$A$58001$

$00000000000008001$
