I suggest to use "__loongarch_lp64" for checking ABI grlen. Consider:
"gcc -march=la464 -mabi=ilp32d ..."
Once ILP32 ABIs are available, will __loongarch_grlen be 64 or 32 in
this case, where the hardware has 64-bit registers but the ABI uses them
as 32-bit? Our documentation is not clear about this question and
currently we understand __loongarch_grlen as hardware GR length instead
of the register length used in ABI [1].
[1]:https://github.com/loongson/LoongArch-Documentation/pull/28#discussion_r917364055
OTOH if you think "we should define __loongarch_grlen as the register
length for ABI, irrelevant to the hardware", you need to inform your
colleagues to clarify it in the doc.

To my intuition it's the hardware GRLEN, but thinking about it harder, there is indeed ambiguity. Some clarification would be useful here. (BTW, Yinyu, could you keep me CC-ed when sending your next revisions? I'd like to take a quick review to ensure there are as few historical warts as possible when the patchset get updated.)
