| * Fix sign of input to bsloww1 (BZ #16623)Siddhesh Poyarekar2014-02-271-6/+10
| | | | | | | | | | | | | | | | In 84ba214c, I removed some redundant sign computations and in the process, I incorrectly got rid of a temporary variable, thus passing the absolute value of the input to bsloww1. This caused #16623. This fix undoes the incorrect change.
* | powerpc: Fix incorrect results for pow when using FMAAdhemerval Zanella2015-03-101-0/+1
|/ | | | | This patch adds no FMA generation for e_pow to avoid precision issues for powerpc. This fixes BZ#18104.

* Fix typo in csloww()Allan McRae2013-12-271-1/+1
| | | | | An incorrect variable name was used during the refactoring done in commit 4aafb73c.
* Consolidate code to compute sin and cos from lookup tablesSiddhesh Poyarekar2013-12-201-232/+129
| | | | | | | | | | | This patch consolidates the multiple copies of code that looks up sin and cos of a number from the lookup table and computes the final value, into static functions. This does not have a noticeable performance impact since the functions are inlined by gcc. There is further scope for consolidation in the functions but they cause a more noticable impact on performance (>5%) due to which I have held back on them.
* Remove more redundant computations in s_sin.cSiddhesh Poyarekar2013-12-201-42/+33
| | | | | | | | Removed more redundant computations in the slow paths of the sin and cos functions. The notable change is the passing of the most significant bits of X to the slow functions to check if X is positive so that just the absolute value of x can be passed and the repeated ABS() operation is avoided.
* Remove redundant arguments in reduce_and_computeSiddhesh Poyarekar2013-12-201-4/+4
| | | | | The A and DA arguments in reduce_and_compute are useless and hence have been removed.
* Remove some redundant computations in s_sin.cSiddhesh Poyarekar2013-12-201-24/+15
| | | | | | | | There are multiple points in the code where the absolute value of a number is computed multiple times or is computed even though the value can only be positive. This change removes those redundant computations. Tested on x86_64 to verify that there were no regressions in the testsuite.

* Minor code cleanup in s_sin.cSiddhesh Poyarekar2013-12-161-20/+13
| | | | | | | - Remove redundant mynumber union definitions - Clean up a clumsy ternary operator - Rename TAYLOR_SINCOS to TAYLOR_SIN since we're only expanding the sin Taylor series in it.
