Elixir Cross Referencer

;# Main file, x.s, with the program (_start) referring to two
;# linkonce functions fn and fn2.  The functions fn and fn2 are
;# supposed to be equivalent of C++ template instantiations; the
;# main file instantiates fn.  An exception-table-lookalike entry
;# refers to fn via a local label.  We use .gcc_except_table as we
;# can't be bothered to produce syntactically valid .eh_frame contents
;# and there's no option to turn off warning messages for invalid
;# contents.
