#!/usr/bin/gawk -f
# Usage: gawk -f linkermapfile-check.awk *.map *.xml
# Order of *.map *.xml is important, otherwise all symbols are reported to be
# missing.
# Checks if all symbols of all locale data are present in the symbol scoping
# linker mapfiles.  Any output indicates a missing symbol, ../localedata.cxx is
# grep'ed to indicate the library to which mapfile the symbol should be added.
