In addition to the types defined in Chapter 3 of the System V Application Binary Interface PowerPC Processor Supplement the following are also supported:
Table 5-1. Extra Auxiliary Types
| Name | Value | Comment |
|---|---|---|
| AT_NOTELF | 10 | Program is not ELF |
| AT_UID | 11 | Real uid |
| AT_EUID | 12 | Effective uid |
| AT_GID | 13 | Real gid |
| AT_EGID | 14 | Effective gid |
| AT_PLATFORM | 15 | String identifying CPU for optimizations |
| AT_HWCAP | 16 | Arch dependent hints at CPU capabilities |
| AT_CLKTCK | 17 | Frequency at which times() increments |
| AT_DCACHEBSIZE | 19 | The a_val member of this entry gives the data cache block size for processors on the system on which this program is running. If the processors have unified caches, AT_DCACHEBSIZE is the same as AT_UCACHEBSIZE |
| AT_ICACHEBSIZE | 20 | The a_val member of this entyr gives the instruction cache block size for processors on the system on which this program is running. If the processors have unified caches, AT_DCACHEBSIZE is the same as AT_UCACHEBSIZE. |
| AT_UCACHEBSIZE | 21 | The a_val member of this entry is zero if the processors on the system on which this program is running do not have a unified instruction and data cache. Otherwise it gives the cache block size. |
| AT_IGNOREPPC | 22 | All entries of this type should be ignored. |
The last three entries in the table above override the values specified in System V Application Binary Interface PowerPC Processor Supplement.
