RISC-V

Assembly and the ABI: Registers, Calling Convention, Stack Frames, ELF

Part 6 of the RISC-V series. I follow the psABI calling convention and stack frame through real C functions. The work() frame was 80 bytes, and arguments from the 9th onward went on the stack. I checked argument locations per ABI and relocations, and linker relaxation shrank .text from 800 bytes to 712 bytes.
