/* Perform arch-dependent adjustments to a register name.

   In very specific situations, it may be necessary for the register
   name present in a SystemTap probe's argument to be handled in a
   special way.  For example, on i386, GCC may over-optimize the
   register allocation and use smaller registers than necessary.  In
   such cases, the client that is reading and evaluating the SystemTap
   probe (ourselves) will need to actually fetch values from the wider
   version of the register in question.

   To illustrate the example, consider the following probe argument
   (i386):

   4@%ax

   This argument says that its value can be found at the %ax register,
   which is a 16-bit register.  However, the argument's prefix says
   that its type is "uint32_t", which is 32-bit in size.  Therefore, in
   this case, GDB should actually fetch the probe's value from register
   %eax, not %ax.  In this scenario, this function would actually
   replace the register name from %ax to %eax.

   The rationale for this can be found at PR breakpoints/24541. */
