[PATCH] D14401: [PGO] Make indexed value profile data more compact and add structural definitions for the data format

[David Li via llvm-commits]

davidxl added a comment.

1. addressed Justin's comments
2. consolidate byte swap code for reader/writer
3. added byte swap related interfaces purely for the purpose of testing

4. increased test coverage by added a new unittest that streams in/out value profile data in big endian order and force byte swapping to happen.
