This doesn't look like gcc/LLD issue. Try compiling the same kernel source with an older version of gcc.
Does the same source build fine with the mentioned older gcc? Or was it building fine on that particular day?

Old gcc compiles normally. Only this newer gcc one doesn't compile.

I'll trigger a build now, check with that. Build will take approximately 6hours.

Unfortunately the error persists.

gcc version: 30082024

It seems like lld specific issue. Try switching from LLD to LD and see if that works.

[TogoFire]

I don't think so. I'm using Fedora. With all dependencies installed.

GCC version 30082024 (RIP):

No it has nothing to do with your system. You're using lld instead of gnu ld. Try using the gnu ld itself.

[TogoFire]

I just tried. It didn't work. It gives the same error.
I tried like this:
"HOSTLD=ld.lld" to "HOSTLD=ld" in script compile.sh
And then I tried removing HOSTLD. And the error persists.

[mvaisakh]

It's not HOSTLD, your kernel cross compiler ld differs. Drop the flag for using LLD with GCC and just use the regular GNU ld.

It's not HOSTLD, your kernel cross compiler ld differs. Drop the flag for using LLD with GCC and just use the regular GNU ld.

In this case you are referring to removing the llvm flags to be able to use LD=$(CROSS_COMPILE)ld ; CC= $(CROSS_COMPILE)gcc ... - From the kernel makefile. Is that it? If so. I removed the "LLVM_IAS=1" "LLVM=1" flags. And the error continues.

I'm sorry if I don't understand or am a bit lost.

[mvaisakh]

Hmm so it does look like a GCC side issue. I think you might need a kernel backport for this. For now you can stick to using older GCC.
