This patch supports RISC-V cycle and instret privilege mode filtering
extension(Smcntrpmf)[1]. It adds two new 64-bits register mcyclecfg
and minstretcfg that configure privilege mode filtering for the cycle
and instret counters, respectively. Remove dropped CSRs that use the
same CSR number with Smcntrpmf extension(mscounteren, mhcounteren).
[1] https://github.com/riscv/riscv-smcntrpmf
bfd/ChangeLog:
* elfxx-riscv.c: New CSR extension.
gas/ChangeLog:
* config/tc-riscv.c (enum riscv_csr_class): New CSR class.
(riscv_csr_address): New handling for CSR class.

* same address drop CSRs.

If we still want to support the privileged versions, then we should use

That might work now, but going forward you won't be able to always only
support the newest version, I suppose.

Hmm, privileged specification 1.10 itself is mature enough (released in
2017) but in the market, there's widely produced chip implementing the
privileged specification 1.9... Kendryte K210.
Because changing the support here have an effect to GDB-based debugging,
dropping support needs to be careful. In the current situation,
modifying 'Smcntrpmf' patch seems better (just using DECLARE_CSR_ALIAS
should work).
If we encounter more severe problem implementing new extensions, I will
start actively supporting to drop old privilege specifications. In this
particular case, I don't see an urgent need to drop 1.9.1 entirely.
Thanks,
Tsukasa
