On the i386, this can be disabled with the -malign-... options. Would it be worthwhile adding similar options to the Alpha to get rid of the ".align 16" statements bloating the install code? Based on a quick study of the code, it should be fairly easy to add a new "-mno-code-align" option and re-write the LOOP_ALIGN and LABEL_ALIGN_AFTER_BARRIER macros. I'll provide patches if this approach seems useful. (Actually implementing all the i386 alignment choices is probably overkill).
