The compiler will currently emit duplicate directory separators when
--remap-path-prefixhas an exact match of the working directory and it is invoked with a relative path to the main source file. For examplerustc src/main.rs -Cdebuginfo=2 --remap-path-prefix="$(pwd)=abc"will produce the path
abc//src/main.rsin debuginfo. This is becausesome_path.join("")will append a directory separator tosome_pathand then LLVM does not check if the working directory already ends a directory separator before concatenating it with the relative path.
