Hi @aemerson @efriedma @ctetreau

#7 0x0000ffffa0f26760 llvm::getLLTForType(llvm::Type&, llvm::DataLayout const&) (/lib64/libc.so.6+0x36760)
 #8 0x0000000002556f74 llvm::computeValueLLTs(llvm::DataLayout const&, llvm::Type&, llvm::SmallVectorImpl<llvm::LLT>&, llvm::SmallVectorImpl<unsigned long>*, unsigned long) (.localalias) (./bin/llc+0x2556f74)
 #9 0x0000000001aeb108 llvm::IRTranslator::getOrCreateVRegs(llvm::Value const&) (.part.0) (./bin/llc+0x1aeb108)
#10 0x00000000019df8a4 llvm::IRTranslator::runOnMachineFunction(llvm::MachineFunction&) (./bin/llc+0x19df8a4)

So clearly we're not falling back on DAG ISel early enough. I'll try to address this in a separate patch.
