Wwhen we see op of phis, we use fake instructions to treat it like we saw ops in the predecessor blocks, and see whether the fake phi we build ends up with real instructions as for the operands. if it does, we insert it.
Note this computation is similar to the one SSAPRE does to...

[NewGVN] Plan for GVNPRE?
Hello,
In some of our internal benchmarks, I observe that LLVM performs worse than GCC because LLVM fails to perform PRE when GCC can. I hope this problem goes away when NewGVN equipped with PRE, and wonder if anyone has an idea about the status of PRE on top of NewGVN. Thanks!
Best,
Taewook
