The DBI stream contains a list of module descriptors. At the beginning of each descriptor is a structure representing the first section contribution in the output file for that module. LLD currently doesn't fill out this structure at all, but link.exe does. So as a precursor to emitting this data in LLD, we first need a way to dump it so that it can be checked. This patch adds support for the dumping, and verifies via a test that LLD emits bogus information. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@330208 91177308-0d34-0410-b5e6-96231b3b80d8
