Hi all I would like to contribute a patch which optimizes Math.exp() for 64 and 32 bit X86 architecture using Intel LIBM implementation. Please review and sponsor this patch. Bug-id: https://bugs.openjdk.java.net/browse/JDK-8132207 <https://bugs.openjdk.java.net/browse/JDK-8132207> webrev: http://cr.openjdk.java.net/~mcberg/8132207/webrev.01/ <http://cr.openjdk.java.net/~mcberg/8132207/webrev.01/>

I have waited for this a long time and I applaud the change! But I’m baffled by the complexity of the implementation ;-) Are there any comments in the original Intel libm implementation which we could add here as well?

Thanks, Vivek
