  "message": "Implement MulAdd() which may perform FMA\n\nrr::MulAdd(x, y, z) computes `x * y + z`, which may be fused into one\n\u0027fused\u0027 operation to produce a higher-precision result. AVX2 features\nFMA instructions which perform a Fused Multiply-Add using just one\nmicro-operation and reducing latency compared to separate multiplication\nand addition.\n\nThis corresponds directly with LLVM\u0027s fmuladd intrinsic:\nhttps://llvm.org/docs/LangRef.html#llvm-fmuladd-intrinsic\nThe backend detects whether FMA is available and more efficient.\n\nSubzero currently does not support AVX2 so it always implements MulAdd()\nas just `a * b + c`.\n\nBug: b/214591655\nChange-Id: Ia5e0d0adc0933e212a2f3f289c2cb75ecdea37cc\nReviewed-on: https://swiftshader-review.googlesource.com/c/SwiftShader/+/61848\nKokoro-Result: kokoro \u003cnoreply+kokoro@google.com\u003e\nTested-by: Nicolas Capens \u003cnicolascapens@google.com\u003e\nReviewed-by: Alexis Hétu \u003csugoi@google.com\u003e\n",
