2026-06-10perf test cs-etm: Replace unroll loop thread with deterministic decode testJames Clark
Testing a long sequence without branches seems like it would be better as a decoder unit test, and this test doesn't test decoding either, so it's not clear what bugs this is trying to catch. The new deterministic workload has somewhat long sequences when built unoptimized, and we can always increase them later if we want to. But now we test that decoding always gives the same result for the same sequence of code which we've never had before.
