https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D257132 --- Comment #4 from imbutler <imb@protected-networks.net> --- It's not only cross-compilation that fails. In an i386 VM and building the GENERIC kernel with a pentium3 target, I get a similar failure .. --- subr_prng.o --- Assertion failed: ((EltVT.getSizeInBits() >=3D 64 || (uint64_t)((int64_t)Va= l >> EltVT.getSizeInBits()) + 1 < 2) && "getConstant with a uint64_t value that doesn't fit in the type!"), function getConstant, file /usr/src/contrib/llvm-project/llvm/lib/CodeGen/SelectionDAG/SelectionDAG.cp= p, line 1337.
