[PATCH] D115615: [MemCpyOpt] Make capture check during call slot optimization more precise

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

Do a captured before check on dest. I initially thought this is already covered by the callCapturesBefore check, but it isn't always.  The `test_dest_captured_before_alloca` test was miscompiled before the additional check.

Thanks for catching!
