Shouldn't the binutils bits go in first? There's basic support for
Zimop/Zcmop from Lyut on the binutils list in late 2023 or early 2024.
I'm pretty sure it marked as DO NOT MERGE because we were waiting for
the extension to get ratified.
Christoph informed me that Zimop has been ratified, so we may not need
to worry about the spec lifecycle status:
https://jira.riscv.org/browse/RVS-1603?src=confmacro
I don't know if Lyut is doing any RISC-V work right now, so if you
wanted to ping the patch on his behalf, it'd be appreciated and I can
handle the review on the binutils side too.
I found that ESWIN's patch to support Zimop on the binutils mailing list
last month:
https://sourceware.org/pipermail/binutils/2024-June/134592.html
I think the GCC bits are fine, but let's get the binutils bits
installed first.
