 596  *  Function:    get_alignment
 597  *
 598  *  Description:
 599  *    According to the info page for gas, the .align directive behaves
 600  * differently on different systems.  On some architectures, the
 601  * argument of a .align directive is the number of bytes to pad to, so
 602  * to align on an 8-byte boundary you'd say
 603  *     .align 8
 604  * On other systems, the argument is "the number of low-order zero bits
 605  * that the location counter must have after advancement."  So to
 606  * align on an 8-byte boundary you'd say
 607  *     .align 3
 608  *
 609  * The reason gas is written this way is that it's trying to mimick
 610  * native assemblers for the various architectures it runs on.  gas
 611  * provides other directives that work consistently across
 612  * architectures, but of course we want to work on all arches with or
 613  * without gas.  Hence this function.
 614  *
 615  *
 616  *  Parameters:
 617  *    align  --  the number of bytes to align to. Must be a power of 2.
