------- Comment #1 from pinskia at gcc dot gnu dot org 2007-03-18 09:49 ------- The only reason why cexp is slow on PPC darwin is because the ABI is stupid. Complex float arguments are passed via the GPR and returned also the same way instead of via the FPRs. So you will get a transfer of registers. This is also true of PPC64 darwin, why they made the same mistake twice I have no idea, guess they did not expect people to use complex that much.
