We also should think longer-term how we want to do these kinds of pattern matches. @rootjalex @abadams In the future, should we consider moving some of these kinds of rules into earlier passes and do them via pattern-matching? |

@shoaibkamil We've discussed separating instruction selection from CodeGen (and I have a slightly stale but still active PR open for doing so on x86, #6884). I was planning on doing this for ARM/HVX as well, but we could definitely do this for some of the GPU backends as well. I think we still need to spend some time on the correct design of the IR for this sort of thing, I think @abadams and I have not come to a conclusion on a few design principles. |
And I know HVX already has HexagonOptimize - but I want to turn some of those passes into proper term-rewriting systems. The current model of "exact pattern goes to specific intrinsic" is rather restrictive and does not support many of the rules that my project has generated. |

Basically, it will generate dot() call for vector_reduce(Add, mul(float, float)). I've tested it locally to make sure it is actually generated. It'd be nice to have something similar to simd_op_check for GPU targets, but it doesn't exist (#7084).
