Detailed Description

template<typename OpTy>
struct EmulateBinaryF32InBF16Pattern< OpTy >

Pattern to emulate f32 binary vector arithmetic ops in bf16.

For an op like: r = arith.addf a, b : vector<16xf32> Produces: a_bf16 = arith.truncf a : vector<16xf32> to vector<16xbf16> b_bf16 = arith.truncf b : vector<16xf32> to vector<16xbf16> r_bf16 = arith.addf a_bf16, b_bf16 : vector<16xbf16> r = arith.extf r_bf16 : vector<16xbf16> to vector<16xf32>
