   1 # This harness is for testing builtin support.  Each test has two files:
   2 #
   3 #    - foo.c defines the main testing function, main_test().
   4 #    - foo-lib.c implements the library functions that foo.c is testing.
   5 #
   6 # The functions in foo-lib.c will often want to abort on certain inputs.
   7 # They can use the global variable inside_main to see whether they are
   8 # being called from the test program or part of the common runtime.
   9 #
  10 # In many cases, the library functions will behave as normal at -O0
  11 # and abort when optimisation is enabled.  Such implementations should
  12 # go into the lib/ directory so that they can be included by any test
  13 # that needs them.  They shouldn't call any external functions in case
  14 # those functions were overridden too.
