Algorithmic changes |
| 14 |
|
------------------- |
| 15 |
|
|
| 16 |
|
* Save big amounts of memory in computation of some functions and constants by: |
| 17 |
|
- Avoiding pre-computation of series terms and instead computing them in a |
| 18 |
|
streamed way. |
| 19 |
|
- Avoiding computation with excess precision in binary splitting algorithm |
| 20 |
|
by coercion of intermediate integer values to floating-point as early as |
| 21 |
|
possible. |

Implementation changes |
| 24 |
|
---------------------- |
| 25 |
|
|
| 26 |
|
* Added support for huge numbers: |
| 27 |
|
- intC used for all counter loops. |
| 28 |
|
- intE is now a 64-bit type on all 64-bit platforms and even on selected |
| 29 |
|
32-bit platforms. |
| 30 |
|
|
| 31 |
|
* CLN now uses C++ exceptions for error handling. The cl_abort() hook is not |
| 32 |
|
supported any more. Please refer to the documentation to learn about existing |
| 33 |
|
exception types. |
| 34 |
|
|
| 35 |
|
* Fixed a bug on i386 where comparing Z/2Z ring zeros returnd random results. |
| 36 |
|
|
| 37 |
|
* Removed cl_boolean. Use built-in C++ bool instead. |

|
* Updated infrastructure to that of libtool-1.5.24. |
| 45 |
|
|
| 46 |
|
* Changed encoding of all files to UTF-8. |
| 47 |
|
|
| 48 |
|
* Fix compilation issues with GCC-4.3. |
| 49 |
|
|
| 50 |
|
* Fix linking issues on platforms that don't feature weak symbols (like win32). |
