[llvm-dev] [GSoC] Unify ways to move code or check if code is safe to be moved

[RITHIK SHARMA via llvm-dev]

Hello,

This is the summary of my Community bonding period week 2, as planned I
spent some time reading loop transformation passes present in
lib/Transforms/, I tried to find the code motion checks in transformation
passes. I was able to find some worthy code motion checks in transformation
passes, I also looked into the Phabricator review D71578 to get familiar
with PR and writing unit tests. isSafeToMoveBefore uses DFS numbering for
determining the relative position of instruction and insert point which is
not always correct, I tried to replicate and fix a test case by using
dominator tree level to decide the direction of code motion and posted a PR
(Phabricator review D80084).

Best Regards,
Rithik Sharma
