[LLVMdev] Vector logic regression in r73431
...ng them with a scalar value?
So could anyone who knows the ins and outs of this code have a look at how
to make it handle vectors correctly? Or if that's not an option right now,
please revert the broken optimizations. Note that there might be more things
affected than visitAnd, visitOr and vistXor, I've only been able to identify
these so far with little knowledge of the actual code. I currently don't
have a reduced testcase, but if really necessary I can try to extract one.
Cheers,
Nicolas
