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)
