@StalkR for some context information, this bug comes from llvm cf https://reviews.llvm.org/D61935

The good way to fix it would be to sync with latest LLVM cf #1510

OK good to know, up to @aquynh then.

When will #1510 be merged?

If not soon, this is a small patch just for the overflow the fuzzers are hitting (Regs[RegNo] with RegNo beyond Regs) that could be used in the meantime.

Sounds good.

@aquynh I guess you will not update PPC soon, so this workaround seems fair.
