Hi! Polite ping:)
4 weeks have passed and there aren't any significant changes in this patch
so I'm thinking of merging it this week if no one minds.

You can only decide to merge it if you would have the authority to
approve patches in this area. In other words, if you were an area
maintainer of the relevant area, or if you were a global maintainer.
Unfortunately, you'll have to continue pinging until a global
maintainer, or risc-v maintainer, approves this.

I would normally approve this on the basis that (1) RISC-V reviews don't
really seem to be happening, (2) you think it is ok, and (3) it only
affects record/replay.
However:
>> include/opcode/riscv-opc.h | 43 +++++++++++++++++++
...this affects other users so I don't know.
Perhaps opcode changes should be sent to the binutils list first.

Hi!
I can't really review the specific risc-v changes, as I'm not familiar
with the architecture, but I do know that this patch is now outdated,
once the "Speeding up RISC-V recording" patch has been merged, since
"set_ordinary_record_type" no longer exists, and there is a conflict
because both patches change need_save_pc to no longer be static.
As far as I can see, this patch looks OK, so I'm fine with giving a
review tag

I'll give this some more time for Andrew or someone with more RISC-V
knowledge to look over, rather than just saying you can push.

Added record-full support for these extensions. As some opcodes were
missed in riscv-opc.h, added them there using riscv-opcodes repo.
Hi! Polite ping. I'm specifying Andrew Burgess as the recipient because
it seems like he's the only one who can approve this from RISC-V side.
