| ** testll.c -- test suite for 64bit integer (longlong) operations |
| ** |
| ** Summary: testll [-d] | [-h] |
| ** |
| ** Where: |
| ** -d set debug mode on; displays individual test failures |
| ** -v verbose mode; displays progress in test, plus -d |
| ** -h gives usage message. |
| ** |
| ** Description: |
| ** lltest.c tests the functions defined in NSPR 2.0's prlong.h. |
| ** |
| ** Successive tests begin to depend on other LL functions working |
| ** correctly. So, ... Do not change the order of the tests as run |
| ** from main(). |
| ** |
| ** Caveats: |
| ** Do not even begin to think that this is an exhaustive test! |
| ** |
| ** These tests try a little of everything, but not all boundary |
| ** conditions and limits are tested. |
| ** You want better coverage? ... Add it. |
