Comment 2 Georgy Yakovlev gentoo-dev 2019-04-12 05:41:45 UTC
was lto ever working with previous versions of rust?


in 1.34.0 changelog I see:

You can now enable linker plugin LTO optimisations with -C linker-plugin-lto. This allows rustc to compile your Rust code into LLVM bitcode allowing LLVM to perform LTO optimisations across C/C++ FFI boundaries.


but it only works if other code is built with llvm/clang
