Sorry, but I don't see how this is relevant; each architecture has its own ABI with its own set of peculiarities, and there's a lot of (completely unrelated) work needed in order to make an ABI that is architecture-agnostic. All this patch set does is provides a consistent way to manipulate scno and args across architectures; it doesn't address the fact that some architectures have mmap2/mmap_pgoff syscall, or that some have fadvise64_64 in addition to fadvise64, or the existence of clone2, or socketcall, or ipc; or that some architectures don't have open or stat; or that scnos on different architectures or even different bit-widths within the "same" architecture are different. > This isn't unique to this patch in any way; the only way to handle it is > by keeping track of each ABI. That's true, but this patch doesn't even try to address that. -- Eugene Syromyatnikov mailto:evgsyr@xxxxxxxxx xmpp:esyr@jabber.{ru|org}
