Understanding RISC-V Calling Convention Arrvindh Shriraman Original document : Nick Riasanovsky Abstract In these notes I will attempt to explain RISC-V calling convention and try and give some understanding for why we use this convention. Hopefully understanding these notes will give you better intuition for understanding RISC- V programs in general, making debugging easier. 1

In Praise of The RISC-V Reader I like RISC-V and this book as they are elegant—brief, to the point, and complete. The book’s commentaries provide a gratuitous history, motivation, and architecture critique. —C. Gordon Bell, Microsoft and designer of the Digital PDP-11 and VAX-11 instruction set architectures This book tells what RISC-V can do and
