   1 Check the test directives used in GCC's testsuite by generating and
   2 running tests that use combinations of those commands or that stress
   3 the selector expressions that can be used in those directives.  Also
   4 run a few tests of specific functionality from the source directory.
   5
   6 Each generated test has two parts: a file ending in "-1.c" whose
   7 expected result is encoded in the filename after "-exp-", and a file
   8 ending in "-2.c" which is always expected to pass.
   9
  10 This test directory is normally skipped and is not meant to be run at
  11 the same time as other parts of the testsuite; it's only of interest to
  12 people who are modifying the test directives or their support in GCC's
  13 .exp files.
  14
  15 To run these tests:
  16
  17     CHECK_TEST_FRAMEWORK=1 make -k check RUNTESTFLAGS="test-framework.exp"
  18
  19 To check the results:
  20
  21     TF=${SRC}/gcc/testsuite/gcc.test-framework
  22     awk -f ${TF}/test-framework.awk gcc/testsuite/gcc/gcc.sum
  23
  24 The awk script prints unexpected results followed by the number of tests
  25 that passed and failed.
