#
# Generate tests of GCC's test framework.  Each test has encoded in
# its name the dg commands that are used in the test and the expected
# result of the test, *-1.c.  Each test is followed by a test ending
# in *-2.c that is expected to pass.
#
# This script has evolved and could be rewritten to be more compact.
