//
// This file contains both the Target independent and Target specific Thunk
// classes
// This file contains Thunk subclasses.
//
// A thunk is a small piece of code written after an input section
// which is used to jump between "incompatible" functions
// such as MIPS PIC and non-PIC or ARM non-Thumb and Thumb functions.
//
// If a jump target is too far and its address doesn't fit to a
// short jump instruction, we need to create a thunk too, but we
// haven't supported it yet.
//
// i386 and x86-64 don't need thunks.
//
// A Thunk Object represents a single Thunk that will be written to an
// InputSection when the InputSection contents are written. The InputSection
// maintains a list of Thunks that it owns.
