Part of the DBI stream is a list of variable length structures describing each module that contributes to the final executable. One member of this structure is a section contribution entry that describes the first section contribution in the output file for the given module. We have been leaving this structure unpopulated until now, so with this patch it is now filled out correctly. Differential Revision: https://reviews.llvm.org/D45832 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@330457 91177308-0d34-0410-b5e6-96231b3b80d8
