Maybe
MF.getProperties().hasProperty(MachineFunctionProperties::Property::NoVRegs))?

Checking when Register Allocation has been performed
Hi LLVM Devs,
I have some shared code that performs lowering operations that can occur
before or after register allocation. When it is pre-RA I want to only use
virtual registers for intermediate results, but post-RA I have to use only a
very restricted set of physical registers.
Code generation using the restricted set is not as efficient as it is when I
can use virtual registers. At
