btw, a follow up patch might be to move the shared lib identifiers from the start of the data section to the end of it so that the re-aligning isnt necessary (we'd get a 4k page alignment from mmap and such). but i cant seem to figure out how these identifiers are being read/written. otherwise, the fact that we're force aligning to 0x20 bytes means that there is always room for 8 identifiers ... no point in flipping between 1 or 4, at least from this point of view ... -mike _______________________________________________ uClinux-dev mailing list uClinux-dev@uclinux.org http://mailman.uclinux.org/mailman/listinfo/uclinux-dev This message was resent by uclinux-dev@uclinux.org To unsubscribe see: http://mailman.uclinux.org/mailman/options/uclinux-dev
