If you have topics to discuss or share, please let me know and I can add them to the agenda. 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- -misa-spec related issue: - Bump default ISA spec to newer version, current default ISA spec is 2.2, but it's already out-of-date for a long time - The most impact is I ext.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=3Drvm20 + -march=3Drv32gc - Or extend syntax of -march option like -march=3Drvm20+mafdc? - RISC-V subextension related implement progress [1] Note: What is RISC-V Profile: https://github.com/riscv/riscv-profiles/ Wei Wu - PLCT Lab is inviting you to a scheduled Zoom meeting.
