Hi Ruslan,

Sorry for the late reply.

Thanks for pointing out the problem, I havenot thought of the questions before, and I found that this patch might also cause problems on other platforms... However, here is a patch created by Sebastian and it should work if your environment supports coshl/sinhl.

Thank you again and wish you a good day! :)

Regards,

Zheng

Hi,

Are you sure this will be of any use if one selects SSE instead of x87
instruction set to handle doubles (like -mfpmath=sse)? No one
guarantees the functions like sinh will be evaluated on x87 FPU and
even that this legacy instruction set will used at all.

Regards,
Ruslan
