This is done because we apply `dllimport` to all // imported constants and this allows everything to actually link correctly. // // The ThinLTO passes aggressively remove symbols if they can, and this test // asserts that the ThinLTO passes don't remove these compiler-generated // `_imp_*` symbols. The external library that we link in here is compiled with // ThinLTO and multiple codegen units and has a few exported constants. Note // that we also namely compile the library as both a dylib and an rlib, but we // link the rlib to ensure that we assert those generated symbols exist. extern crate msvc_imp_present as bar; fn main() { println!("{}", bar::A); }
