Can't you just put an ELF symbol (can be an unnamed local -- could even just be a section symbol) on the index section, then add a pointer in the IR section with a relocation to that symbol? This is basically how DWARF .debug_info sections point to the abbrev table in the .debug_abbrev sections. -cary
