[PATCH] D120168: [Debuginfo][LSR] Add support for salvaging variadic dbg.value intrinsics [1/2]

[Chris Jackson via Phabricator via llvm-commits]

chrisjackson updated this revision to Diff 414360.
chrisjackson added a comment.

Restore the the old behaviour for transforming DIArglist location arguments to single- location op:.  When trying to determine the type of an undef Value that has become a nullptr, simply abandon the salvage attempt. This restores the NFC status of this patch.

In the second patch in this series, this code block is removed.
