--- Comment #2 from kahrl at gmx dot net --- Created attachment 36909 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=36909&action=edit Code that compares tgamma and tgammaq. Link with -lm -lquadmath. When run, generates the two files tgamma.dat and tgammaq.dat which contain the return values of tgamma and tgammaq, respectively, for input values between -5.0 and 5.0. These output files can be used as datafiles with gnuplot to clearly see the difference between tgamma (correct) and tgammaq (incorrect).
