Attaching the config for "ld.lld: error: Never resolved function from blockaddress (Producer: 'LLVM12.0.0' Reader: 'LLVM 12.0.0')"And here is a new one: "ld.lld: error: assignment to symbol init_pg_end does not converge"This is interesting. I changed the symbol assignment to a separate loop in https://reviews.llvm.org/D66279 Does raising the limit help? Sometimes the kernel linker script can be rewritten to be more friendly to the linker...
If that requires rebuilding lld, testing it is beyond what I can help with
right now. Hopefully someone can reproduce it with my .config.
