BF16 FP8: checking precision across two CPU compiler versions

A dtype conversion can remain visible after the final FP8 quantization. It belongs in a fusion's numerical contract, even when its intermediate allocation is removed. Here is a small CPU example: x = torch . tensor ([ 1.0626 ], dtype = torch . float32 ) x . to ( torch . bfloat16 ). to ( torch . flo…
