2*4882a593Smuzhiyun  * Declare directives for structure packing. No padding will be provided
3*4882a593Smuzhiyun  * between the members of packed structures, and therefore, there is no
4*4882a593Smuzhiyun  * guarantee that structure members will be aligned.
5*4882a593Smuzhiyun  *
6*4882a593Smuzhiyun  * Declaring packed structures is compiler specific. In order to handle all
7*4882a593Smuzhiyun  * cases, packed structures should be delared as:
8*4882a593Smuzhiyun  *
9*4882a593Smuzhiyun  * #include <packed_section_start.h>
10*4882a593Smuzhiyun  *

12*4882a593Smuzhiyun  *    some_struct_members;
13*4882a593Smuzhiyun  * } BWL_POST_PACKED_STRUCT foobar_t;
