Does anyone know how to obtain the overall spill cost for the old reg alloc of GCC (global.c)?
We don't have existing hooks for this, but it shouldn't be hard for you to add them yourself. Try looking at the code, see in particular dump_global_regs in global.c and the uses of dump_file in reload1.c.
