I'm building ports on aarch64 to see how things go and am looking for common problems. At this stage, mostly just wanting to show people what things I run into so they can mull them over. (I'll also fix simple things as I go).
One that I'm seeing is undefined symbols with the following math functions, undefined symbol '__floatunditf' undefined symbol '__fixunstfsi' undefined symbol '__fixunstfdi' For example in archivers/gtar, audio/musepack, devel/dconf. These names are in InitLibcallNames() in /usr/src/gnu/llvm/lib/CodeGen/TargetLoweringBase.cpp Names[RTLIB::UINTTOFP_I64_F128] = "__floatunditf"; Names[RTLIB::FPTOUINT_F128_I32] = "__fixunstfsi"; Names[RTLIB::FPTOUINT_F128_I64] = "__fixunstfdi"; A number of the other symbols in this file aren't found in libm, but I haven't run into problems with those yet. (Ports is likely not clean enough to build those ports with what's currently in-tree, at the moment I have 800-odd Ms for WANTLIB changes).
