This updated version of patch looks > good to me, but I'd leave the approval to Segher/David. Thanks! Yes, I've been waiting for Segher or David's approval for this for awhile. The history is it is indeed a latent issue (not supporting __ibm128 complex multiply and divide when long double is IEEE 128-bit). However, at the time I wrote it, the other changes had broken the complex multiply and divide, and I wrote this patch as part of the series. I separated the patch from the other 2 to make it simpler to go in. But it seems to be in limbo. -- Michael Meissner, IBM PO Box 98, Ayer, Massachusetts, USA, 01432 email: meissner@linux.ibm.com
