- /*
- * 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).
