2014-02-27Fix sign of input to bsloww1 (BZ #16623)Siddhesh Poyarekar1-6/+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.

2013-12-27Fix typo in csloww()Allan McRae1-1/+1
An incorrect variable name was used during the refactoring done in commit 4aafb73c.
2013-12-20Consolidate code to compute sin and cos from lookup tablesSiddhesh Poyarekar1-232/+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.
2013-12-20Remove more redundant computations in s_sin.cSiddhesh Poyarekar1-42/+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.
2013-12-20Remove redundant arguments in reduce_and_computeSiddhesh Poyarekar1-4/+4
The A and DA arguments in reduce_and_compute are useless and hence have been removed.
2013-12-20Remove some redundant computations in s_sin.cSiddhesh Poyarekar1-24/+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.
