-/**
- * When generating any kind of backtrace (gdb, exception handling) for
- * a function called in a Fiber, we need to tell the unwinder to stop
- * at our Fiber main entry point, i.e. we need to mark the bottom of
- * the call stack. This can be done by clearing the link register lr
- * prior to calling fiber_entryPoint (i.e. in fiber_switchContext) or
- * using a .cfi_undefined directive for the link register in the
- * Fiber entry point. cfi_undefined seems to yield better results in gdb.
- * Unfortunately we can't place it into fiber_entryPoint using inline
- * asm, so we use this trampoline instead.
