--- Comment #1 from Ed Smith-Rowland <3dw4rd at verizon dot net> 2013-02-06 04:39:43 UTC --- Created attachment 29362 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=29362 Patch including testcase and other cleanups. This patch adds a check for zero argument to a Bessel function series. This patch removes unnecessary const for floating point and integral arguments. Finally, a better asymptotic expansion for Bessel functions is provided.
