[AMD] Undefined behavior sanitizer invalid-bool-load in optimize_epilogue.mlir
gflegar opened this issue · comments
This is an AMD-only test, which we don't have the bandwidth to look at at the moment, but our sanitizers detected an issue with it. So filing this in case someone on the AMD side wants to fix it. Here is the stack trace:

Could you share the input ir for this pass? I cannot find third_party/triton/test/TritonGPU/optimize_epilogue.mlir
.
This is the test: https://github.com/triton-lang/triton/blob/main/test/TritonGPU/optimize_epilogue.mlir
This one is test in CI and it works fine. I also tested it on MI300 and it also works fine.
@gflegar Are you using the latest main branch? And could you share the GPU and rocm version info?
My understanding from the message is that it only fails when running with UB sanitizer (we don't have those runs in CI)

Ah, yes, I missed that part. Thanks for the clarification.
