Description
Risc-V calling conventions are described in "RISC-V ABIs Specification", in the chapter "RISC-V Calling conventions".
For the current state only integer registers are relevant. Objects that are 2 words wide are passed in 2 registers. Larger types are passed by reference. Note that the referenced object can be modified by the callee, so it is not enough to pass a reference to a local variable to the callee, the local variable should be copied first, so that the callee cannot modify caller's local variables.
