That's what matt@ seems to think as well. I wonder if he ever tried to build anything natively on his mips64 hardware. Also, isn't this supposed to work on Linux/MIPS? Last time I checked they were using n32 as default ABI. The real problem is probably somewhere else and I'm just working around it. > i think they could be commited right now, but please add > an entry to doc/HACKS. Will do, thanks. The compiler definitely works with this on sgimips ( built a couple packages like perl, gmake, tcsh with working results, perl's make test is still running and seems to pass pretty much everything ), I didn't get around to do more torturing on Loongson yet. Symptoms were the same though, alignment faults from gmp's assembly routines doing 64bit ops on 32bit data when using -On with n>0. have fun Michael
