As for memory constraint you should not to return true for a pseudo. Reload/LRA can figure out how to match a spilled pseudo with memory (but this constraint should be define_memory_constraint, i saw mistakes when people used different forms of constraints for memory and had problems).
For its own reasons, xtensa returns true for a pseudo during reload for a memory type constraint that shouldn't use the constant pool but doesn't mark it as a memory constraint. What will that architecture lose because of that and will it work for lra?
