… r=alexcrichton Drop long-section-names linker workaround for windows-gnu If we can trust objdump Rust doesn't emit sections loaded at runtime longer than 8 characters on windows-gnu (but still does on linux-gnu), debug sections are not affected by that limit. I've ran tests and built few crates using exactly the same mingw-w64 version as Rusts CI just fine using **x86_64** toolchain. The motivation for this change is making LLD work (it doesn't support `--enable-long-section-names`) with this target without hacks. Bit of history: The behaviour of LD changed in Binutils 2.20 released on 2009-10-16 and `--enable-long-section-names` was added to return to the old non conformant behaviour. Looking at the comment I can only guess there was a bug fixed in newer versions. This workaround was added in rust-lang#13315 half a decade ago.

FWIW I tested new nightly on few old Ubuntu versions and I think we should not regress. |
