* 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.
* BZ#13889: expl (709.75) wrongly overflows for ldbl-128ibmAdhemerval Zanella2013-03-222-6/+24
| | | | | | The patch increase the high value to check if expl overflows. Current high mark value is not really correct, the algorithm accepts high values. It also adds a correct wrapper function to check for overflow and underflow.
* Fix Bessel function spurious overflows for ldbl-128 / ldbl-128ibm (bug 15285).Joseph Myers2013-03-212-20/+34
|
* Replace 8388608.0 with HALFRAD in mp codeSiddhesh Poyarekar2013-03-212-3/+3
| | | | Minor cleanup
* Fix y1l spurious overflows for ldbl-96 (bug 15283).Joseph Myers2013-03-161-1/+1

* Fix spurious underflow exceptions for Bessel functions for ldbl-128 / ↵Joseph Myers2013-03-162-58/+79
| | | | ldbl-128ibm (bug 14155).
* Better distinguish between NaN/qNaN/sNaN.Thomas Schwinge2013-03-151-5/+5

* 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
|
* PowerPC: unify math_ldbl.h implementationsAdhemerval Zanella2013-03-081-2/+8
| | | | | This patch removes redudant definition from PowerPC specific math_ldbl, using the definitions from ieee754 math_ldbl.h.

|
* 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.

| | | | 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
