1- For the following C statement, what is the corresponding RISC-V assembly code? Assume that the variables x, y, h, and i are given and could be considered integers as declared in a C program. Use a minimal number of assembly instructions. Also, use the variables as opposed to register values. h=(x - y) + (i-1) 2- For the following RISC-V assembly instructions below, what is a single corresponding C statement? Assume f, g, h, i are in x18, x19, x20 and x21. Your answer must be one single C statement for all assembly instructions as opposed to one C statement for each assembly instruction. sub x18, x19, x20 add x18, x18, x21 3- Registers in RISC-V are 64-bit. For the sake of simplicity, consider the following instructions operating on 32-bit registers. Assume that registers x5 and x6 hold the values OxBBBBBBBB and 0x00000000, respectively. - What is the value in x6 for the following slli x6, x5, 6 -Using the result from the part above, what is the value in x6 for the following instruction. srli x6, x6, 6
