Q not supported in GCC 14
The wally-toolchain-installation script pulls the latest version of riscv-gnu-toolchain, which was recently updated to use GCC 14. This fails to recognize q as a valid extension in the -march string, which causes it to fail when building several of our tests.
Would it make sense to lock the commit the script uses at https://github.com/riscv-collab/riscv-gnu-toolchain/commit/b488ddbd6cdc7d2b951f4bccacc324818356bfc3 until the issue with 14 can be resolved? That's the last commit before the update.
I'm currently stuck on this, so let me know when you make the change, or I can make it when I have a chance.
Temporarily pinned in #972. This should be investigated further so that we can switch to GCC 14 at some point down the road.
@djdiaz You might need to delete your existing installation if you already tried since the script will only install newer versions by default, not older versions.
Thank you! Will it be enough to simply rebuild and install the RISC-V toolchain, or are there downstream dependencies that also need to be rebuilt?
I haven't tried switching to an older gcc version before so not positive, but I think you should be fine to just rebuild the RISC-V toolchain. elf2hex can be finicky and might also need to be rebuilt.
