2 | /* Common header file that is included by all of QEMU. |
3 | * | |
4 | * This file is supposed to be included only by .c files. No header file should | |
5 | * depend on qemu-common.h, as this would easily lead to circular header | |
6 | * dependencies. | |
7 | * | |
8 | * If a header file uses a definition from qemu-common.h, that definition | |
9 | * must be moved to a separate header file, and the header that uses it | |
10 | * must include that header. | |
