1 | /* |
2 | * linux/asm-sparc/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). | |
