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