   4 /* PR 96983 reported that the test in libgcc's tramp.S was backwards and it
   5    would abort if the trampoline size passed to the function was greater than
   6    the size the runtime was expecting (40).  It should abort if the size is less
   7    than 40, not greater than 40.  This test creates a call to __trampoline_setup
   8    with a much larger buffer to make sure the function does not abort.
   9
  10    We do not run this test on 64-bit since __trampoline_setup is not present in
  11    64-bit systems.
  12
  13    We only run the test under Linux in case the other systems have some
  14    different variant for __trampoline_setup.  */
