[llvm-commits] PR12343 PATCH: -loop-unswitch crash on indirect branch

[Stepan Dyatkovskiy]

Hi all. Please find patch for review.
It was discussed here:
http://llvm.org/bugs/show_bug.cgi?id=12343

We have not trivial way for splitting edges that are goes from indirect branch. We can do it with some tricks, but it should be additionally discussed. And it is still dangerous due to difficulty of indirect branches controlling.

This is a fast fix, that forbids this case for unswitching.

-Stepan.
