Sometimes program headers have larger alignments than any of the sections they contain. Currently yaml2obj can't produce such files. A bug recently appeared in llvm-objcopy that failed in such a case. I'd like to be able to add tests to llvm-objcopy for such cases. This change adds an optional alignment parameter to program headers that will be used instead of calculating the alignment. Differential Revision: https://reviews.llvm.org/D39130 llvm-svn: 317139
