* New <math.h> macro named issignaling to check for a signaling NaN (sNaN).Thomas Schwinge2013-04-022-0/+89
| | | | It is based on draft TS 18661 and currently enabled as a GNU extension.

|
* Use integral constantsSiddhesh Poyarekar2013-03-261-76/+76
| | | | | | The compiler is smart enough to convert those into double for powerpc, but if we put them as doubles, it adds overhead by performing those operations in floating point mode.
* Removed commented codeSiddhesh Poyarekar2013-03-2611-85/+0
|
* Make mantissa type of mp_no configurableSiddhesh Poyarekar2013-03-263-69/+101
| | | | | | | | | | The mantissa of mp_no is intended to take only integral values. This is a relatively good choice for powerpc due to its 4 fpus, but not for other architectures, which suffer due to this choice. This change makes the default mantissa a long integer and allows powerpc to override it. Additionally, some operations have been optimized for integer manipulation, resulting in a significant improvement in performance.
* Replace 8388608.0 with HALFRAD in mp codeSiddhesh Poyarekar2013-03-212-3/+3
| | | | Minor cleanup
* Revert configurable mantissa patchSiddhesh Poyarekar2013-03-153-92/+60
| | | | | | Reverts d22ca8cdfb98001d03772ef264b244930d439b3f since it is severely broken on 32-bit.
* Make mantissa type configurableSiddhesh Poyarekar2013-03-153-60/+92
| | | | | This allows the default mantissa to be integral, with powerpc overriding it to take advantage of its FPUs.
* Fix spurious underflow exceptions for Bessel functions for double (bug 14155).Joseph Myers2013-03-142-4/+8

|
* Another tweak to the multiplication algorithmSiddhesh Poyarekar2013-02-261-6/+50
| | | | | Reduce the formula to calculate mantissa so that we reduce the net number of multiplications performed.
* Don't duplicate mpone and mptwoSiddhesh Poyarekar2013-02-261-5/+3

* Remove commented declarationsSiddhesh Poyarekar2013-02-251-14/+0
|
* Use long wherever possible in mpa.cSiddhesh Poyarekar2013-02-251-31/+39
| | | | | | Using long throughout like powerpc does is beneficial since it reduces the need to switch to 32-bit instructions. It gives a very minor performance improvement.

|
* 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.
