In compiler optimization, register allocation is the process of assigning a large number of target program variables onto a small number of CPU registers. Register allocation can happen over a basic block (local register allocation), over a whole function/procedure (global register allocation), or in-between functions as a calling convention (interprocedural register allocation).

Famous quotes containing the word register:
“A funeral is not death, any more than baptism is birth or marriage union. All three are the clumsy devices, coming now too late, now too early, by which Society would register the quick motions of man.”
—E.M. (Edward Morgan)
