C language OD. machine code What program converts assembly language into machine code? Select one: O A. an assembler B. BIOS O C. Linux O D. a compiler Assume RO holds an 8-bit value. Assume registers have been initialized so that R1 contains Ob10101010, R2 contains Ob01010101, R3 contains Ob11001100 and R4 contains Ob00110011. Restrict yourself to using only AND, OR, LSR, LSL and SWAP and a total of no more than 13 instructions to write a program that reorders the bits in RO such that upon completion all initial 8 bits are stored in bit-reversed order within RO. - Us X X E? : 44 B 1 AN EE? 21 va 2 Ix o 2 Which program converts high-level languages into machine code?
