<https://sourceware.org/pipermail/binutils/2022-February/119858.html>
v2:
<https://sourceware.org/pipermail/binutils/2022-May/120974.html>
CURRENT (GitHub):
<https://github.com/a4lg/binutils-gdb/tree/riscv-s-exts-csrs>
This patchset adds CSRs for following extensions:
- Smstateen
- Sscofpmf
- Sstc
Because 'H' extension and related CSR class is now implemented, we can
now safely and consistently implement hypervisor-related CSR feature
gate masking.
[CHANGES: v2 -> v3]
- Follow up to now implemented 'H' extension support
- Add (and refactor) complex CSR feature gate handling (on H and RV32)
- Make new CSRs independent to privileged architecture
(as initially suggested by Nelson Chu)
Thanks,
Tsukasa
