[PATCH 0/2] RISC-V: Support CORE-V XCVMAC and XCVALU extensions

[Mary Bennett]

This patch series presents the comprehensive implementation of the MAC and ALU
extension for CORE-V.

Tested with riscv-gnu-toolchain on binutils, ld, gas and gcc testsuites to
ensure its correctness and compatibility with the existing codebase.
However, your input, reviews, and suggestions are invaluable in making this
extension even more robust.

The CORE-V instructions are described in the specification [1] and work can be
found in the OpenHW group's Github repository [2].
