** 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.
|
