From: "muecker at gwdg dot de" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug ipa/96503] attribute alloc_size effect lost after inlining Date: Wed, 25 Oct 2023 05:46:26 +0000 [thread overview] Message-ID: <bug-96503-4-d3XPx4KHy2@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-96503-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=96503 Martin Uecker <muecker at gwdg dot de> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |muecker at gwdg dot de --- Comment #3 from Martin Uecker <muecker at gwdg dot de> --- Was just to file this bug... Note that the access attribute could be translated into the same builtin suggested for counted_by in https://gcc.gnu.org/pipermail/gcc-patches/2023-October/634177.html and then this could work. This would also simply the BDOS path I think because special code for the access attribute could go. Example: https://godbolt.org/z/1TTePn7hn static #if 0 char *propagate(char *p, int s) [[gnu::access(read_only, 1, 2)]] #else char *propagate(char *p; int s; char p[(p = pointer_with_size(p, s), s)], int s) #endif { printf("%ld\n", __builtin_dynamic_object_size(p, 0)); return p; }
