For reference, Andrew Waterman and others in the RISC-V team looked at using function calls to register store/load helper functions to reduce size overhead in epilogues and prologues as an alternative to supporting load-multiple and store-multiple in the ISA. David Patterson described some of this work at the last RISC-V workshop http://riscv.org/workshop-jun2015/riscv-compressed-workshop-june2015.pdf. See slide 15.
