◆ UnbundleArchive()

Error OffloadBundler::UnbundleArchive ( )

UnbundleArchive takes an archive file (".a") as input containing bundled code object files, and a list of offload targets (not host), and extracts the code objects into a new archive file for each offload target.

Each resulting archive file contains all code object files corresponding to that particular offload target. The created archive file does not contain an index of the symbols and code object files are named as <<Parent Bundle Name>-<CodeObject's TargetID>>, with ':' replaced with '_'.

Map of target names with list of object files that will form the device specific archive for that target

Iterate over all bundled code object files in the input archive.

Write out an archive for each target
