Hi Tim,
I believe that's the NEON VMLA, not the VFP one. There was a discussion in

Turns out I was misreading the assembly. I wish "vmla" and "vfma"
weren't so similar-looking.
For Suyog that means the option "-ffp-contract=fast" is needed to get
vfma when needed. Sorry about the bad information earlier.
Cheers.
Tim.
