Conversation
The comment here was a bit misleading, rust-lang#13846 was about an LLVM assertion that failed when `-Zfunction-sections` was enabled. However, that bug has been fixed for a long time and the actual issue was that older `ld` versions would not correctly link binaries (see rust-lang#75604 for the prior attempt at this change). This bug was fixed in version 2.32 of binutils and Rust now ships binutils 2.42 as of rust-lang#119229 so we can remove this workaround!

I don't know whether it still triggers an assertion because Rust doesn't build do LLVM build with assertions enabled for Windows GNU. The assertion is probably gone because functions sections work fine with Clang+LLD (gnullvm targets are built with function sections). |
