We can look it up in gcc release log which states
We can also verify it manually. According to ARM Architecture manual VFPv4 at least added
Vector Fused Multiply Accumulate / Subtract.Compiling this with
-mfpu=neon-vfpv4switch (otherwise my tool chain saysError: selected processor does not support ARM mode 'vfma.f32 q1,q2,q3')and dumping the binary for with
should list below
However I don't know how you can use this at C level since I couldn't find any intrinsic listed for these fused instructions or think of any other way.
