[Patch][binutils][arm] Armv8.6-A Matrix Multiply extension [9/10]
Hi,
This patch is part of a series that adds support for Armv8.6-A
(Matrix Multiply and BFloat16 extensions) to binutils.
This patch introduces the Matrix Multiply (Int8, F32, F64) extensions
to the arm backend.
The following Matrix Multiply instructions are added: vummla, vsmmla,
vusmmla, vusdot, vsudot[1].
