| 36 | * v4_early - ARMv4 without Thumb early abort handler |
| 37 | * v4t_late - ARMv4 with Thumb late abort handler |
| 38 | * v4t_early - ARMv4 with Thumb early abort handler |
| 39 | * v5tej_early - ARMv5 with Thumb and Java early abort handler |
| 40 | * xscale - ARMv5 with Thumb with Xscale extensions |
| 41 | * v6_early - ARMv6 generic early abort handler |
