* Function: get_alignment
|
|
|
|
*
|
|
|
|
* Description:
|
|
|
|
* According to the info page for gas, the .align directive behaves
|
|
|
|
* differently on different systems. On some architectures, the
|
|
|
|
* argument of a .align directive is the number of bytes to pad to, so
|
|
|
|
* to align on an 8-byte boundary you'd say
|
|
|
|
* .align 8
|
|
|
|
* On other systems, the argument is "the number of low-order zero bits
|
|
|
|
* that the location counter must have after advancement." So to
|
|
|
|
* align on an 8-byte boundary you'd say
|
|
|
|
* .align 3
|
|
|
|
*
|
|
|
|
* The reason gas is written this way is that it's trying to mimick
|
|
|
|
* native assemblers for the various architectures it runs on. gas
|
|
|
|
* provides other directives that work consistantly across
|
|
|
|
* architectures, but of course we want to work on all arches with or
|
|
|
|
* without gas. Hence this function.
