So more work is needed on the GMP side :-( Note the size of pointers, 16 bytes. There is no integer type mathing that, so if code tries to cast a pointer through some integer type for, say, aligning it, things will break. Apparently, this is some sort of research platform. I have no idea how hard a GMP port might be, I've given up trying to make GMP run well on Arm since it is too hard and too expensive to find hardware for 90% of the Arm cores. There are lots of "Fruit Pi" boards, but they all use a small set of processor cores (essentially A55, A72, and A73) or cost and arm (no pun intended) and a leg. But GMP at least runs on most Arm cores, as long as they follow the standard ABI. -- Torbjörn Please encrypt, key id 0xC8601622 _______________________________________________ gmp-bugs mailing list gmp-bugs@gmplib.org https://gmplib.org/mailman/listinfo/gmp-bugs
