Specifically, around 3-5% regression on x86-64 in various metrics of the [Interpolation](https://github.com/llvm/llvm-test-suite/tree/main/MicroBenchmarks/ImageProcessing/Interpolation) benchmarks, and up to 30% regression on a number of floating point-centric benchmarks from https://github.com/llvm/llvm-test-suite/tree/main/SingleSource/Benchmarks/Misc (flops-4.c, flops-5.c, flops-6.c, flops-8.c, fp-convert.c). The numbers vary depending on the microarchitecture, with Skylake being less affected (on the order of ~10%) and AMD Rome showing larger regressions (up to 30%).
