Definition

a0–a7 ( RISC-V)

a0 through a7 are the RISC-V integer registers x10 through x17. They are argument registers used to pass integer or pointer arguments to a function.

a0 and a1 are also used to return integer or pointer values from a function. Arguments beyond a7 are passed on the stack according to the RISC-V calling convention.
