# Wildcard target for test code generation:
# A .c file is generated for each .data file in the suites/ directory. Each .c
# file depends on a .data and .function file from suites/ directory. Following
# nameing convention is followed:
#
#     C file        |        Depends on
#-----------------------------------------------------------------------------
#  foo.c            | suites/foo.function suites/foo.data
#  foo.bar.c        | suites/foo.function suites/foo.bar.data
#
# Note above that .c and .data files have same base name.
# However, corresponding .function file's base name is the word before first
# dot in .c file's base name.
