  "message": "Tweaks to e2e matmul tests (#15930)\n\nThis restricts the range of random `bf16` test matrix elements, so that\r\nwe avoid larger-accumulation-size matmul tests getting accumulators \u003e\u003d\r\n256, at which point integers are no longer exactly representable in\r\n`bf16` and accumulation becomes very inaccurate. This is what was\r\ncausing test failures on large tests specifically in\r\nhttps://github.com/openxla/iree/pull/15911 .\r\n\r\nThis also fixes the computation of the window of the test matrices that\r\nis displayed on error. The problem arose when diagnosing a matmul test\r\nerror in cases where M and N are both small, and K is larger. The new\r\nwindow computation is also just simpler.",
