I didn't see an obvious explanation for your troubles here. There are other targets like IA-64 that do not have base+offset addressing modes. It should just work. LEGITIMIZE_RELOAD_ADDRESS is a hack. It should never be necessary for correct code generation, in theory, though I think there are some rare corner cases where it may be required for correct results. Long term this is something that should be fixed. Meanwhile, I can point out that the IA-64 port does not define LEGITIMIZE_RELOAD_ADDRESS, and does not have base+offset addressing modes, and it works. IA-64 does have auto-increment addressing modes, but those shouldn't matter here. Reload won't generate such addressing modes for a stack slot reference. Jim
