SVE Instruction List by Dougall Johnson
BFMLALT (vectors): BFloat16 floating-point multiply-add long to single-precision (top)
BFMLALT Zda.S, Zn.H, Zm.H (SVE+BF16 (SME+BF16
svfloat32_t svbfmlalt[_f32](svfloat32_t op1, svbfloat16_t op2, svbfloat16_t op3)
128-bit SVE

For each odd BFloat16 float calculate (1) * (2), and add that to the 32-bit float from (3), then set (4) to the result.
256-bit SVE

For each odd BFloat16 float calculate (1) * (2), and add that to the 32-bit float from (3), then set (4) to the result.
512-bit SVE

For each odd BFloat16 float calculate (1) * (2), and add that to the 32-bit float from (3), then set (4) to the result.
