I have a Java app which uses some intensive FP, for which I have written native (aka: C) routines to accelerate. I am getting to the point where I am once again tapped out, so I want to explore hand coded MMX instructions in my (unrolled, hand optimized) inner loops. I have "ordered" the MMX dox from INTEL, and expect them any day now, so I need to start preparing for the next step: namely a gcc/gas which understands the MMX mmxnomnics. A .h file with nice asm macros already defined for the instructions would be nice also (although, I can type if pressed). I've seen discussions on MMX here, and on pgcc. I went to build the pgcc port once, and was informed that it was broken. I am running -current, cvsupped, cvsupping ports, and there is no Makefile in ports/lang/pgcc*. I suspect I might get a bit of a perf boost if I were to use pgcc. Help? To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe hackers" in the body of the message
