Probably a typo. In M4 generic user guide the mnemonic for floating-point MAC is shown as VLMA

How exactly are you using these instructions?

Perhaps there is a mistake.

VLMA mnemonics is found in only one document. But the description and function are similar to VMLA mnemonics.

The difference is VMLA's ability to handle double precision.

The latest version of GCC swears at VLMA mnemonics.

There are many applications:

a += b * c;

a -= b * c;
