- Test driver for low-level BigNum library correctness.
- In addition to the generic "bntest" program, which picks a size
- at compile time, there are specific test drivers, bntest16,
- bntest32 and bntest64 that you can compile specifically, e.g.
- to test multiple word sizes.
- bntest is different from other programs in that it invokes the
- low-level BigNum functions directly. It need only be linked with
- lbnmem.o, lbn32.o and legal.o. This is not normally desirable, but
- it lets this test driver isolate errors better in the bottom-level
- primitives.
- It's served very well in tracking down errors. If you write some new
- assembly primitives and it doesn't find a problem with them, you
- can have a good deal of confidence that they're correct.
- This program also does timing tests on basic modular exponentiation.
- It is invoked as bntest [modsize [expsize [expsize2]]].
- If modsize is not specified, it only runs consistency checks.
- If expsize is not specified, it defaults to modsize.
- If expsize2 is not specified, it defaults to expsize.
- Invalid arguments produce a usage message.
- Example invocation lines:
- bntest
- bntest 512
- bntest 1024 160
