> Project: ORC
> Issue Type: Improvement
> Components: C++
> Reporter: Fang Zheng
> Priority: Minor
>
> This is a follow-up of ORC-444. The following functions in RLEV2Util.hh can
> be optimized by replacing the if-else statements with direct array lookup:
> inline uint32_t getClosestFixedBits(uint32_t n);
> inline uint32_t getClosestAlignedFixedBits(uint32_t n);
> inline uint32_t encodeBitWidth(uint32_t n);
> inline uint32_t findClosestNumBits(int64_t value);
