This chapter describes two more conditional branch instructions and two conditional set instructions. Set instructions set a register to 1 or 0 depending on whether a condition is true or false.
bltz instruction (branch on less than zero)bgez instruction (branch on greater or equal to zero)slt instruction (set on less than) sltu instruction (set on less than, unsigned) slti instruction (set on less than, immediate) sltiu instruction (set on less than, immediate unsigned) These new instructions help you implement loops and branches. But this is still a difficult task. Study this chapter to gain insight into what compilers do for you.
