Write risc-v assembler code for the following recursive function using the calling convention shown in the risc-v reference data int y) { int ack(int x, if (x == 0) return y + 1; else if (y return ack(x - 1, 1); else return ack(x - 1, ack(x, y - 1)); 0) == (c) consider the following risc-v code that atomically increments a shared variable in memory: x5, (x10) x5, x5, 1 x28, x5, (x10) x28. x0, incr x0, (ra) incr 1r. d addi sc. d bne jalr suppose two processors start executing this code at exactly the same time, and that each executes exactly one instruction per cycle.
