History

Move RemoveRedundantDbgInstrs outside of inner loop in JumpThreading (#123008 )

This cleanup action only needs to be performed once when the entire
optimization is converged. Doing it in every iteration has a very high
time-complexity, as it queries every dbg value in a dense map

Compare before and after for one internal source file with many basic
blocks
