* Use __sqr instead of __mul wherever possibleSiddhesh Poyarekar2013-02-143-4/+4
|
* New __sqr function as a faster special case of __mulSiddhesh Poyarekar2013-02-143-2/+94
|
* Remove unnecessary factorial arraySiddhesh Poyarekar2013-02-131-10/+3
| | | | kf is n! at the end of the loop, so storing the values is unnecessary.
* Better exp polynomialSiddhesh Poyarekar2013-02-131-23/+37
| | | | The lesser the __mul calls, the better it is for performance.
* Optimized mp multiplicationSiddhesh Poyarekar2013-02-131-8/+48
| | | | Don't bother multiplying zeroes since that only wastes cycles.

|
* Update copyright notices with scripts/update-copyrights.Joseph Myers2013-01-02196-201/+196
|
* Fix values in __mpexp_twomm1Siddhesh Poyarekar2013-01-021-8/+8
|
* Split mantissa calculation loop and add branch predictionSiddhesh Poyarekar2013-01-021-24/+43
|
* Add assert for potential access beyond array bounds in m1npSiddhesh Poyarekar2013-01-021-4/+17
| | | | | | | | | | | The mpexp code has an access into m1np: for (i=n-1; i>0; i--,n--) { if (m1np[i][p]+m2>0) break; } which could break for p >= 18 or i >= 7. Fortunately this code is never called due to the way the exp function is implemented since values having exponent less than -55 return 1.0. Make sure that if it gets called in future, it is trapped.

| | | | | The number 134217729.0 gets used in various places in e_pow.c but there is no explanation of what that number is. Add that explanation.
