Hi all,
There is an agenda for tomorrow's meeting. If you have topics to
discuss or share, please let me know and I can add them to the agenda.
We should also talk about the ABI spec, we've now got a handful of
incompatibilites between it and the binaries we currently
generate/accept.
Agenda:
- -misa-spec related issue:
- Bump default ISA spec to newer version, current default ISA spec
is 2.2, but it's already out-of-date for a long time
- The most impact is I ext. will bump to 2.1, which is
backward incompatible with 2.0, I 2.1 has split csr instruction to
zicsr ext. and ifence.i to zifencei ext., that might break some
existing build script.
- Discuss new scheme for -misa-spec or alternative scheme for
dealing with RISC-V profile
- Interaction between -march and RISC-V profile[1].
- Introduce -mprofile option: -mprofile=rvm20 + -march=rv32gc
- Or extend syntax of -march option like -march=rvm20+mafdc?
- RISC-V subextension related implement progress
