[PATCH] D41659: Implementing missing trigonometric optimizations

[ADIL ARUN DANGUI via Phabricator via llvm-commits]

cs15btech11041 created this revision.

Here we have implemented the following missing trigonometric optimizations.

1. tan(x)*cos(x)=sin(x)
2. sin(x)*cos(x) = sin(2*x)/2
3. sin(x)/tan(x)=cos(x);
4. tan(x)/sin(x)=1/cos(x);
