Author: emaste Date: Thu Nov 24 00:45:00 2016 New Revision: 309075 URL: https://svnweb.freebsd.org/changeset/base/309075 Log: MFC r308772: crunchide: report explicit error for combined string table Some tools produce objects with a combined strtab and shstrtab. These objects are not supported by crunchide since it rewrites the symtab and strtab to "hide" symbols. This invalidates section header offsets into a combined strtab/shstrtab. In the future we could support these objects (by ensuring that we retain unmodified section name strings in the output .strtab, and then rewriting each section header's sh_name).
