[PATCH] D145218: Can SubRangeJoin, attribute of JoinVals, be modified by target? Why is this attribute set to false now?

[Quentin Colombet via Phabricator via llvm-commits]

qcolombet added a comment.

I don't think this is correct.
Here we are merging the main live-ranges, so if we set the join subrange flag we may not check the right thing. In particular, the `LaneBitmask` in this call is incorrect, unless I am mistaken, for a subrange check.
