/*
* Copyright 2014 Andy Lutomirski
* Subject to the GNU Public License, v.2
*
* Hack to keep broken Go programs working.
*
* The Go runtime had a couple of bugs: it would read the section table to try
* to figure out how many dynamic symbols there were (it shouldn't have looked
* at the section table at all) and, if there were no SHT_SYNDYM section table
* entry, it would use an uninitialized value for the number of symbols. As a
* workaround, we supply a minimal section table. vdso2c will adjust the
* in-memory image so that "vdso_fake_sections" becomes the section table.
*
* The bug was introduced by:
* https://code.google.com/p/go/source/detail?r=56ea40aac72b (2012-08-31)
* and is being addressed in the Go runtime in this issue:
* https://code.google.com/p/go/issues/detail?id=8197
