 * linux/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).
