7** testll.c -- test suite for 64bit integer (longlong) operations
8**
9** Summary: testll [-d] | [-h]
10**
11** Where:
12** -d set debug mode on; displays individual test failures
13** -v verbose mode; displays progress in test, plus -d
14** -h gives usage message.
15**
16** Description:
17** lltest.c tests the functions defined in NSPR 2.0's prlong.h.
18**
19** Successive tests begin to depend on other LL functions working
20** correctly. So, ... Do not change the order of the tests as run
21** from main().
22**
23** Caveats:
24** Do not even begin to think that this is an exhaustive test!
25**
26** These tests try a little of everything, but not all boundary
27** conditions and limits are tested.
28** You want better coverage? ... Add it.
