Hmm, so apparently just linking in libgcc leads to duplicated symbols with the ones in compiler-builtins, which causes a linker error.

Any ideas?

Hm I'm not sure how to solve that :(

I thought this was tested ahead of time though to work?

I only tested the aarch64 musl toolchain, which worked fine. It seems that the x86_64 one is failing.

Maybe we should just include the needed symbols directly in compiler-builtins?

We can, yes, but I think this is likely to eventually bite us for aarch64, no?

Not really. This is the issue for aarch64: rust-lang/compiler-builtins#201
If we just add the __addtf3, __subtf3 and __multf3 builtins then it will be enough to fix the bug.

Another possibility would be to mark all the builtins in compiler-builtins as weak, which will resolve the linking issue since it will use the version from libgcc instead in all cases.

We may want to just have aarch64 specific build logic in that case (vendored into this repository) which statically links libgcc but a stripped down version (one that we don't ship as well). That would only contain the objects needed to get libc iteslf linking and compiling correctly, and it'd only be intrinsics that aren't already provided by compiler-builtins. Is that possible?

This feels very fragile. What about other architectures that may depend on libgcc functions?

I had a quick look at the musl source code, the only other architectures which need libgcc support for long double are mips64 and s390x, but we don't currently have musl targets for those.

FWIW, the reason that compiler-rt includes support for many builtins that are never called by LLVM is for link-time compatibility with GCC-generated code. Maybe we should be doing the same with compiler-builtins?

Looking at aarch64 musl, it calls all of the following long double builtins:

__addtf3
__divtf3
__multf3
__subtf3
__eqtf2
__extenddftf2
__extendsftf2
__getf2
__gttf2
__letf2
__lttf2
__netf2

It is purely by coincidence that when we link to libc we only need 3 of these for a small test program.

It's true that it's fragile but I'm not really sure if there's a better solution here? I'm up for whatever if it's more robust

Ping from triage! @Amanieu we haven't heard from you for a while, will you have time to work on this PR?

I think that we will have to revert the libc changes and try another approach. I'm closing this PR.
