[PATCH] D57834: [CodeExtractor] Only lift lifetime markers present in the extraction region

[Sergei Kachkov via Phabricator via llvm-commits]

kachkov98 added a comment.

Just for note: it seems that skipping extracting lifetime.start when lifetime.end can't be lifted (in 2nd option) can again lead to miscompile as in https://reviews.llvm.org/D55967 (assume that markers for x and y in rhs are not lifted). It's safer to extract all lifetime.start markers referencing inputs to mark them all as simultaneously used, as in option (1).
