| 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). |
