GBE: let GenRegister::reg() never return uninitialized memory #16

Closed michaellass closed 3 years ago

michaellass commented 4 years ago

GenRegister::reg() is called throughout the code, not only on virtual but also on physical registers. For the latter, value.reg is not initialized and therefore reg() returns uninitialized memory, leading to undefined behavior. Make sure to always return initialized memory by returning a valid ir::Register, even for physical registers.
