[PATCH] D75600: Add nullptr check to isLandingPad

[Florian Hahn via Phabricator via llvm-commits]

fhahn added a comment.

Hm I think calling isLandingPad on an empty (=invalid) basic block might be a pre-condition violation we legitimately want to crash on (with assertions isa<> assert != 0)?  I suspect there are a lot of functions that expect BBs with at least a valid terminator and would crash for empty basic blocks. Unless I am missing something I think it might be better to avoid calling it on invalid block in the client code.
