  • Adding support for new instructions increases the complexity of binutils.
  • Supporting experimental extensions may require changes as the extension evolves.

RISC-V: Add experimental support for Zvabd extension
tldr
The RISC-V Zvabd extension is ready; the author asks for the binutils patch to land so the GCC patch isn't blocked.

Re: [PATCH] RISC-V: Add experimental support for Zvabd extension

Chen Zhongyao notes that the RISC-V Zvabd extension is now in the “Freeze” state and asks Jiawei to pick up the binutils patch. The corresponding GCC patch is ready but blocked, pending the binutils changes.
