Classes
struct	Instruction
	Instruction structure. More...
struct	reconvergencePoint
	Represents a reconvergence point in a warp It has PC value and active mask to indicate which threads are active at the reconvergence point. Might need to be extend in the future to add some metadata to handle more complex reconvergence scenarios. More...
class	Warp
	Represents a GPU warpThe Warp class encapsulates the state and behavior of a GPU warp, including its ID, program counter, threads, active mask, and current instruction. A warp is a group of threads that execute instructions in lockstep. Each warp has 32 threads in this project. To be added: reconvergence stack to handle divergent control flow. More...
