Why are generic dag combines run before target dag combines?
Hi llvm-dev,
I just tried to implement a target-specific dag combine to preempt a
generic dag combine, and I was surprised to see that it didn't work because
the generic dag combines are run first. Does anyone know the rationale for
running the generic dag combines first? I would have expected the target
dag combines to run first because they have more specific information about
what combines
