RISC-V failed to build int8 MobileNetV2 with LLVM Integrate #16055 about iree HOT 6 CLOSED

posting how to get mlir file here, I think you can download the file from one of CI jobs, e.g., gcloud storage cp gs://iree-github-actions-presubmit-artifacts/7422301781/1/e2e-test-artifacts/iree_MobileNetV2_int8_tflite_.mlir ~/

You can add --iree-hal-dump-executable-sources-to=/tmp/dump to dump dispatches; it might help narrowing it down to specific dispatch. Then you can use iree-compile with --compile-mode=hal-executable flag to generate the VMFB. Hopefully it could help narrow down the issue.

Hey @rednoah91, could anybody from your side help with this?

iree-compile: /home/hanchung/iree/third_party/llvm-project/llvm/lib/Transforms/Scalar/LoopUnrollPass.cpp:659: std::optional<EstimatedUnrollCost> analyzeLoopUnrollCost(const llvm::Loop *, unsigned int, llvm::DominatorTree &, llvm::ScalarEvolution &, const SmallPtrSetImpl<const llvm::Value *> &, const llvm::TargetTransformInfo &, unsigned int, unsigned int): Assertion `UnrolledCost.isValid() && RolledDynamicCost.isValid() && "All instructions must have a valid cost, whether the " "loop is rolled or unrolled."' failed.

I talked to @rednoah91 today, and he can help take a look at this. @rednoah91 please let us know if someone is taking a look at this.

I've tried the ToT build (6ab1ed) but can not reproduce the error.

It seems to be fixed by some upstream changes. We can re-enable the model, I will prepare the PR
