See reproducer at https://drive.google.com/file/d/1sdznuNjRXXl2whBczMhL0OpLlLVzXBRP/view?usp=sharing. (NB: the reproducer uses ThinLTO and was built against 99d0780f050c830c046c6f8790821880ab7c71f5)
The above reproducer hangs when building ToT LLVM with Android's [regalloc models] (https://android.googlesource.com/platform/prebuilts/clang/host/linux-x86/+/refs/heads/main/mlgo-models/arm64/regalloc-evict-aosp/). (I haven't been able to build with official MLGO-released-models yet).
