C++ (Cpp) sparc_supply_fpregset Examples

Example #1

  /* NOTE: cagney/2002-12-03: This code assumes that the currently
     selected light weight processes' registers can be written
     directly into the selected thread's register cache.  This works
     fine when given an 1:1 LWP:thread model (such as found on
     GNU/Linux) but will, likely, have problems when used on an N:1
     (userland threads) or N:M (userland multiple LWP) model.  In the
     case of the latter two, the LWP's registers do not necessarily
     belong to the selected thread (the LWP could be in the middle of
     executing the thread switch code).

     These functions should instead be paramaterized with an explicit
     object (struct regcache, struct thread_info?) into which the LWPs
     registers can be written.  */
