For example:

./bin/llc -O3 test.ll -o /dev/null -print-machineinstrs=greedy
WORKS WELL PRINTS MACHINE INSTRUCTIONS

./bin/llc -O3 feature-cache.ll -o /dev/null -print-machineinstrs=pbqp

llc:/home/.../llvm/lib/CodeGen/TargetPassConfig.cpp:843: virtual void
llvm::TargetPassConfig::addMachinePasses(): Assertion `TPI && IPI && "Pass ID
