Register Allocation

Register allocation compiler — virtual registers mapped to physical CPU registers through graph coloring and liveness analysis

Register Allocation in Compilers: How Variables Fit into CPU Registers

Discover how compilers solve register allocation — mapping thousands of virtual registers to 16 (x86-64) or 31 (ARM64) physical ones. See graph coloring, spilling, and rematerialization with real Godbolt examples.
