| | | | | | it should use add with carry or conditional moves if available. Also remove the amd64 asm; the mp_amd64 code should be used for this case.

* Malloc_Allocator isn't a pool, so it needs to fail directly if malloclloyd2010-09-261-1/+3

* There is a pretty common pattern in the code for testing for internallloyd2010-09-263-0/+86
| | | | | | | | | | errors of the form if(some_expr_indicating_failure) throw Internal_Error("Some mildly informative message"); Make this simpiler with the addition of a BOTAN_ASSERT macro which will throw an exception upon failure.
* At some point I 'simplified' the divide code to always run thelloyd2010-09-261-1/+5
| | | | | | | | | | division algorithm unless x == y, but this could result in n - t + 1 being negative which would cause an attempt to allocate about 4 gigabytes of memory. Fix this, and also add an assertion check in the code to ensure that can't happen in any other way. Never reproduced this with 32 bit digits but it would show up if the build used 8 or 16 bit words.

* Modify bigint_monty_redc to take an additional workspace argument.lloyd2010-09-245-71/+83
| | | | | | | Modify it to avoid a timing condition during the compare at the end; this is done by always doing the subtraction, and then copying to the output either the pre-subtraction or post-subtraction value depending on if the final borrow was set or not.
