  19 # This harness is for testing builtin support.  Each test has two files:
  20 #
  21 #    - foo.c defines the main testing function, main_test().
  22 #    - foo-lib.c implements the library functions that foo.c is testing.
  23 #
  24 # The functions in foo-lib.c will often want to abort on certain inputs.
  25 # They can use the global variable inside_main to see whether they are
  26 # being called from the test program or part of the common runtime.
  27 #
  28 # In many cases, the library functions will behave as normal at -O0
  29 # and abort when optimisation is enabled.  Such implementations should
  30 # go into the lib/ directory so that they can be included by any test
  31 # that needs them.  They shouldn't call any external functions in case
  32 # those functions were overridden too.
