[regression][GPU]: 'func.func' op uses 81920 bytes of shared memory; exceeded the limit of 65536 bytes post 6ff00a8a008d06b604d4ca4e0ae6e601ae810b4f

What happened?

We have 100+ models failing in GPU which were earlier passing numeric and started post 6ff00a8

module {
  func.func @torch_jit(%arg1:!torch.vtensor<[1,128,4,256],f32>) -> !torch.vtensor<[1,257,4,256],f32    > attributes {torch.onnx_meta.ir_version = 7 : si64, torch.onnx_meta.opset_version = 21 : si64, torch.onnx_meta.producer_name = "pytorch", torch.onnx_meta.producer_version = "1.12.1"} {

Which 100 models? Please be specific in bug reports.

[ScottTodd]

Here's the list of test failures: https://github.com/nod-ai/e2eshark-reports/blob/main/2024-12-17/ci_reports_onnx/rocm/combined-reports/yesterday_comparison.md#317-regressions-found. Lots in the "vit" family (vision transformers)

[ScottTodd]

Good news: with the existing tests in https://github.com/iree-org/iree-test-suites/tree/main/onnx_models, I can reproduce a regression in a few models like mobilenet and resnet50 using --iree-hal-target-backends=rocm --iree-hip-target=gfx1100. So once I land PRs to get those tests running on multiple backends, we should have earlier signal for these sorts of regressions.

[ScottTodd]

Repro using resnet from iree-org/iree-test-suites#65:

# Setup
cd onnx_models
.\.venv\Scripts\activate.bat
pip install --upgrade -r requirements-iree.txt

# Run test that passes
pytest --log-cli-level=info -rA --durations=0 -k resnet --test-config-file=./configs/onnx_models_gpu_rocm_rdna3.json

# Switch to broken release, run again to see failure
pip install --find-links https://iree.dev/pip-release-links.html iree-base-compiler==3.1.0rc20241217
pytest --log-cli-level=info -rA --durations=0 -k resnet --test-config-file=./configs/onnx_models_gpu_rocm_rdna3.json

Once that PR and #19524 land we'll have that coverage on all IREE PRs.

I also noticed that this error spews a looooot of logs (multiple thousands of lines):

iree/compiler/src/iree/compiler/Codegen/Common/GPU/GPUCheckResourceUsage.cpp

Lines 85 to 87 in fb4d094

	return funcOp.emitOpError("uses ")
	<< cumSize << " bytes of shared memory; exceeded the limit of "
	<< limit << " bytes";

Maybe we don't need the entire context?
