// This file provides a way to combine bitcode files into one COFF
// file by compiling them using LLVM.
//
// If LTO is in use, your input files are not in regular COFF files
// but instead LLVM bitcode files. In that case, the linker has to
// convert bitcode files into the native format so that we can create
// a COFF file that contains native code. This file provides that
// functionality.
