The local register allocator (local-alloc.c) has been removed in the upcoming 4.4.x series of compilers so you might want to try something else. Doing it during register allocation seems tricky, a machine-specific reorg pass could be more appropriate. I'm not sure we already have something like this in the compiler (SPARC has a double-load instruction but it's only implemented as a peephole). -- Eric Botcazou
