   2  * linux/asm-sparc64/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).
