--- Comment #4 from Paul Floyd <pjfl...@wanadoo.fr> --- Trying to see where the redir is going wrong and thinking that there is an iFunc. On RHEL, for instance, libc contains plenty: nm /lib64/libc.so.6 | grep " i " ... 000000000008b100 i strcat ... Just came accross this https://maskray.me/blog/2021-01-18-gnu-indirect-function And according to https://github.com/freebsd/freebsd-src/blob/main/lib/libc/amd64/string/stpcpy.S and https://github.com/freebsd/freebsd-src/blob/main/lib/libc/amd64/amd64_archlevel.h FreeBSD now has GNU indirect functions. That means that vg_preloaded.c needs to change from #elif defined(VGO_freebsd) // nothing specific currently #elif defined(VGO_solaris) to containing something like the Linux version: void * VG_NOTIFY_ON_LOAD(ifunc_wrapper) (void) { OrigFn fn; Addr result = 0; Addr fnentry; /* Call the original indirect function and get it's result */ VALGRIND_GET_ORIG_FN(fn); CALL_FN_W_v(result, fn); fnentry = result; VALGRIND_DO_CLIENT_REQUEST_STMT(VG_USERREQ__ADD_IFUNC_TARGET, fn.nraddr, fnentry, 0, 0, 0); return (void*)result; } -- You are receiving this mail because: You are watching all bug changes.
