# How this file works
# ===================
#
# Whenever a .elf file is modified,
# a corresponding .err file is generated to save the model error message
# for this file.  When the test suite is processed the next time, e.g.,
# after some hacking on the HELF implementation, the new error message
# is compared to the saved one.  If they do not match, this is considered
# an error.  Then one has to verify the new error message is actually the
# intended one (manually), and remove the .err file.

# Enable read -n and 2>&1 |.
SHELL=bash

helf=helf

# Getting all elf files

allout=$(patsubst %.elf,%.err,$(allelf))
