   1/*
   2 * linux/asm/reg.h
   3 * Layout of the registers as expected by gdb on the Sparc
   4 * we should replace the user.h definitions with those in
   5 * this file, we don't even use the other
   6 * -miguel
   7 *
   8 * The names of the structures, constants and aliases in this file
   9 * have the same names as the sunos ones, some programs rely on these
  10 * names (gdb for example).
