| 20 | * We have the following to choose from: |
| 21 | * arm6 - ARM6 style |
| 22 | * arm7 - ARM7 style |
| 23 | * v4_early - ARMv4 without Thumb early abort handler |
| 24 | * v4t_late - ARMv4 with Thumb late abort handler |
| 25 | * v4t_early - ARMv4 with Thumb early abort handler |
| 26 | * v5tej_early - ARMv5 with Thumb and Java early abort handler |
| 27 | * xscale - ARMv5 with Thumb with Xscale extensions |
| 28 | * v6_early - ARMv6 generic early abort handler |
| 29 | * v7_early - ARMv7 generic early abort handler |
