6994 ;; Instructions to load a call address from the GOT. The address might
6995 ;; point to a function or to a lazy binding stub. In the latter case,
6996 ;; the stub will use the dynamic linker to resolve the function, which
6997 ;; in turn will change the GOT entry to point to the function's real
7000 ;; This means that every call, even pure and constant ones, can
7001 ;; potentially modify the GOT entry. And once a stub has been called,
7002 ;; we must not call it again.
7004 ;; We represent this restriction using an imaginary, fixed, call-saved
7005 ;; register called GOT_VERSION_REGNUM. The idea is to make the register
7006 ;; live throughout the function and to change its value after every
7007 ;; potential call site. This stops any rtx value that uses the register
7008 ;; from being computed before an earlier call. To do this, we:
7010 ;; - Ensure that the register is live on entry to the function,
7011 ;; so that it is never thought to be used uninitalized.
7013 ;; - Ensure that the register is live on exit from the function,
7014 ;; so that it is live throughout.
7016 ;; - Make each call (lazily-bound or not) use the current value
7017 ;; of GOT_VERSION_REGNUM, so that updates of the register are
7018 ;; not moved across call boundaries.
7020 ;; - Add "ghost" definitions of the register to the beginning of
7021 ;; blocks reached by EH and ABNORMAL_CALL edges, because those
7022 ;; edges may involve calls that normal paths don't. (E.g. the
7023 ;; unwinding code that handles a non-call exception may change
7024 ;; lazily-bound GOT entries.) We do this by making the
7025 ;; exception_receiver and nonlocal_goto_receiver expanders emit
7026 ;; a set_got_version instruction.
7028 ;; - After each call (lazily-bound or not), use a "ghost"
7029 ;; update_got_version instruction to change the register's value.
7030 ;; This instruction mimics the _possible_ effect of the dynamic
7031 ;; resolver during the call and it remains live even if the call
7032 ;; itself becomes dead.
7034 ;; - Leave GOT_VERSION_REGNUM out of all register classes.
