Routine calling convention information and associated metadata

Fields

volatile_registers: Vec<RegisterDesc>

List of registers that may change as a result of the routine execution but will be considered trashed

param_registers: Vec<RegisterDesc>

List of regsiters that this routine wlil read from as a way of taking arguments

• Additional arguments will be passed at [$sp + shadow_space + n * 8]

retval_registers: Vec<RegisterDesc>

List of registers that are used to store the return value of the routine and thus will change during routine execution but must be considered “used” by return

frame_register: RegisterDesc

Register that is generally used to store the stack frame if relevant

shadow_space: u64

Size of the shadow space

purge_stack: bool

Purges any writes to stack that will be end up below the final stack pointer
