| abi | common |
| entry point | sys_dup2 |
| since | Linux 5.0 or earlier (5.0 is the first release scanned for ia64) |

Registers
| register | value |
|---|---|
r15 | 1070, the syscall number |
out0 | unsigned int oldfd |
out1 | unsigned int newfd |
r8 | the return value |
Then run break 0x100000 to enter the kernel.
The kernel uses r10 to signal an error.
The pipe call returns file descriptors in r8 and r9.
This architecture was removed from the Linux kernel in Linux 6.7. The newest release with a syscall table here is Linux 6.6. The other removed architectures live on the historical architectures page.
