In compiler optimization, register allocation is the process of assigning local automatic variables and expression results to a limited number of processor registers.
Register allocation can happen over a basic block (local register allocation), over a whole function/procedure (global register allocation), or across function boundaries traversed via call-graph (interprocedural register allocation). When done per function/procedure the calling convention may require insertion of save/restore around each call-site.
