321 * Function: get_alignment
324 * According to the info page for gas, the .align directive behaves
325 * differently on different systems. On some architectures, the
326 * argument of a .align directive is the number of bytes to pad to, so
327 * to align on an 8-byte boundary you'd say
329 * On other systems, the argument is "the number of low-order zero bits
330 * that the location counter must have after advancement." So to
331 * align on an 8-byte boundary you'd say
334 * The reason gas is written this way is that it's trying to mimick
335 * native assemblers for the various architectures it runs on. gas
336 * provides other directives that work consistantly across
337 * architectures, but of course we want to work on all arches with or
338 * without gas. Hence this function.
342 * alignBoundary -- the number of bytes to align to.
343 * If we're on an architecture where
344 * the assembler requires a 'number
345 * of low-order zero bits' as a
346 * .align argument, then this number
347 * must be a power of 2.
