Assuming that i and j are in X3, X4 respectively, and assuming that the base address of the long arrays A and B (each element is 8 bytes) are in registers X6 and X7, respectively, write the LEGv8 assembly instructions for the following C statement:
B[8] = A[i - j];
Homework Answers
Compiled LEGv8 Code :
index 8 require offset of 64 (8*8)
LDUR X9,[X7,#64] //(LOAD REGISTER,U FOR UNSCALED IMMEDIATE) temporary register X9 contains B[8]
SUB X9 ,X3, X4 //temporary register X9 contains [i-j]
STUR X6, X9 //(STORE REGISTER ), register X6 gets [i-j]
STUR X9, X6 //store A[i-j] back into B[8]
