1 | /* |
| 2 | * Part of the execve tests. This program should not be compiled fat. xnu_quick_test | |
| 3 | * will call the various single-architecture builds of this program as helpers to test | |
| 4 | * the exec() transitions it cannot test itself. | |
| 5 | * | |
| 6 | * When running on a 64-bit machine (x86_64 or PPC64), the 32-bit version of | |
| 7 | * xnu_quick_test will fork and exec a 64-bit helper process that performs | |
| 8 | * the following tests. | |
| 9 | * 1. 64 bit process forking() 64-bit child, child execing() 64-bit file(4GB pagezero) | |
| 10 | * 2. 64 bit process forking() 64-bit child, child execing() 64-bit file (4KB pagezero) | |
| 11 | * 3. 64 bit process forking() 64-bit child, child execing() 32-bit file | |
| 12 | * | |
| 13 | * The 64-bit version of xnu_quick_test will fork and exec a 32-bit process | |
| 14 | * that performs the following tests. | |
| 15 | * 4. 32 bit process forking() 32-bit child, child execing() 32-bit file | |
| 16 | * 5. 32 bit process forking() 32-bit child, child execing() 64 bit file (4GB pagezero) | |
| 17 | * 6. 32 bit process forking() 32-bit child, child execing() 64 bit file (4KB pagezero) | |
