// The frames of each of the two functions below contain two locals, at offsets
// that are known to the runtime.
//
// The first local is a bool called retValid with a whole pointer-word reserved
// for it on the stack. The purpose of this word is so that the runtime knows
// whether the stack-allocated return space contains valid values for stack
// scanning.
//
// The second local is an abi.RegArgs value whose offset is also known to the
// runtime, so that a stack map for it can be constructed, since it contains
// pointers visible to the GC.
