# This file contains the necessary information to compile add-c.c.  Two
# executable files are generated: add-c.elf, with -O2 optimisation, and
# add-c-noopt.elf, without any compiler optimisation.

# You can use this file by typing:
#     make -f add-c.make
# Generated files can be removed by typing:
#     make -f add-c.make clean
