Thanks. Could you try follow https://wiki.gentoo.org/wiki/Gcc-ICE-reporting-guide?
(In reply to Sam James from comment #4) > Thanks. Could you try follow > https://wiki.gentoo.org/wiki/Gcc-ICE-reporting-guide? sorry, to be specific, I mean, if you're willing: * cvise it * report it upstream If you aren't able to do one or both of those, that's fine, just let us know and one of toolchain@ or riscv@ can handle it. Thanks!
I’ll work on cvise and reporting to upstream when I find time. I’ll also join gentoo-riscv on IRC.
