Question

For the following RISC-V assembly code, assume that the variables f, g, h, i, and j are assigned

to registers x5, x6, x7, x28, and x29, respectively. Assume that the base address of the arrays A
and B are in registers x10 and x11, respectively.
addi x30, x10, 8
addi x31, x10, 0
sd x31, 0(x30)
ld x30, 0(x30)
add x5, x30, x31
Write the equivalent C code for this RISC-V assembly code

Answer 1

The equivalent C code for the given RISC-V assembly code assigns variables f, g, h, i, and j to registers and performs some memory operations.

Step-by-step explanation:

The given RISC-V assembly code assigns variables f, g, h, i, and j to registers x5, x6, x7, x28, and x29 respectively. It also assumes that the base addresses of the arrays A and B are in registers x10 and x11 respectively.

The equivalent C code for the given assembly code can be written as:

int* x30 = (int*) (x10 + 8);
int* x31 = (int*) x10;
*x31 = 0;
int* x30 = *x30;
f = x30 + x31;
