--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> --- "Large symbols and symbols that must exist in exactly one instance in the running program probably should be a part of (nonexistent) libgcov.so.0." which are those? I expected individual gcov "instances" to live across dynamic object lifetime. That is, does a shared libgcov fix the case of dlopen()ing and dlclose()ing shared objects (multiple times)? --- Comment #3 from Martin Liška <marxin at gcc dot gnu.org> --- Author: marxin Date: Thu Oct 4 12:41:14 2018 New Revision: 264840 URL: https://gcc.gnu.org/viewcvs?rev=264840&root=gcc&view=rev Log: Fix divergence in indirect profiling (PR gcov-profile/84107). 2018-10-04 Martin Liska <mli...@suse.cz> PR gcov-profile/84107 * tree-profile.c (init_ic_make_global_vars): Remove ic_void_ptr_var and ic_gcov_type_ptr_var.
