I would like to contribute a patch which optimizes Math.sin() and Math.cos() for 64 and 32 bit X86 architecture using Intel LIBM implementation.
The improvement gives ~4.25x gain over base for both sin and cos.
The option to use the optimizations are -XX:+UseLibmSinIntrinsic and -XX:+UseLibmCosIntrinsic.
Could you please review and sponsor this patch.
Thanks and regards,
