- * vdso_test.c: Sample code to test parse_vdso.c on x86
- * Copyright (c) 2011-2014 Andy Lutomirski
- * Subject to the GNU General Public License, version 2
- *
- * You can amuse yourself by compiling with:
- * gcc -std=gnu99 -nostdlib
- *     -Os -fno-asynchronous-unwind-tables -flto -lgcc_s
- *      vdso_standalone_test_x86.c parse_vdso.c
- * to generate a small binary.  On x86_64, you can omit -lgcc_s
- * if you want the binary to be completely standalone.
