[PATCH] D60831: [DebugInfo at O2][LoopVectorize] pr39024: Vectorized code linenos step through loop even after completion

[Orlando Cazalet-Hyams via Phabricator via llvm-commits]

Orlando added a comment.

Ping.

A summary of the discussion so far:

The middle block is quite "latch like" in that it dictates control flow between the vectorized and scalar loops, but it can contain additional
instructions. For example, it may also handle converting the vectorized results into a scalar value.

The patch maps all middle block instructions to the line of the loop latch branch.

An initial question of "How much will this affect profiling tools that rely on this debug info?" was not fully addressed because
discussions on an alternative solution I mentioned eclipsed the original question.
