------------------------------
Summary: [C++] Code improvements in RLEV2Util
Key: ORC-445
URL: https://issues.apache.org/jira/browse/ORC-445
Project: ORC
Issue Type: Improvement
Components: C++
Reporter: Fang Zheng
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);
