  "message": "Subzero: Build a better bitcast.\n\nThe x86 lowering of bitcast between integers and floats forced the transfer through a stack slot (the original implementer *cough* *cough* wasn\u0027t aware of the movd instruction).  This requires excess instructions, but also a store to memory followed immediately by a load from that location is very slow.\n\nThis fixes the problem by using the movd instruction instead.\n\nBUG\u003d none\nR\u003djpp@chromium.org\n\nReview URL: https://codereview.chromium.org/2077503002 .\n",
