#
# This makefile builds all of the C programs in this directory in three
# different configurations:
#   1. By the native GCC compiler
#   2. To LLVM bytecode
#   3. To Sparc machine code, from bytecode, using LLC
#
# After building all of these different forms, the programs are run and the
# output is diff'd
#
#  FIXME: There should be a way to specify libraries to link programs against
#  FIXME: There should be a way to specify the command line for a program
#
#  IDEA: This could be specified in the start of the .c file, in a comment block
