------- Comment #6 from dje at gcc dot gnu dot org 2009-12-03 01:44 ------- Darwin and AIX share most of the C code and the assembly files are nearly identical for 32 bit support, except for the format of calls. The results on AIX now are clean. I cannot see any reason for the difference between the AIX results and the Apple regression tester results. The regression tester results look identical to the results you posted with your long double fix and without my additional patches.
