Both x86 and ia64 now provide a dynamically shared object (DSO) for
system call purposes (e.g., to speed up system calls and for signal
trampoline/sigreturn purposes). At the moment, the names of these
DSOs are different:
I think there is some value in using the same name on all platforms
that support such a DSO. vsyscall makes no sense for ia64, since
there are no virtual syscalls (instead, ia64 linux provides a fast
system call convention which, when coupled with light-weight system
call handlers, provide full syscall semantics at more or less the
speed of virtual system calls).
Not surprisingly, I like the name "linux-gate", since that is really
what this DSO is all about: it's a gateway between user and kernel
space. However, if this name isn't appropriate for x86, perhaps we
can find another name which will be acceptable to everybody.
I already checked with Roland McGrath (cc'd), and he agrees that a
common name would be good and said that he doesn't care about the
particular name that will be used.
Does anyone have any strong feelings about this? If not, I plan to
submit a patch to rename the x86 DSO to linux-gate.so.1.
