// 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.
