77    general, we need to be able to get hold of the values of specific
78    registers, in order to start the unwinding process.  This is
79    unavoidably arch and platform dependent.  Here is a struct which
80    holds the relevant values.  All platforms must have a program
81    counter and a stack pointer register, but the other fields (frame
82    pointer? link register? misc other regs?) are ad-hoc.  Note, the
83    common fields are 64-bit, so as to make this host-independent. */
