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