10596 * gimple-fold.c (get_range_strlen_tree): Record if the computed
10597 length is optimistic. If it is, then arrange to compute the
10598 conservative length as well.
10600 * gimple-fold.h (get_range_strlen): Update prototype.
10601 * builtins.c (check_access): Update call to get_range_strlen to use
10602 c_strlen_data pointer. Change various variable accesses to instead
10603 pull data from the c_strlen_data structure.
10604 (check_strncat_sizes, expand_builtin_strncat): Likewise.
10605 * calls.c (maybe_warn_nonstring_arg): Likewise.
10606 * tree-ssa-strlen.c (maybe_diag_stxncpy_trunc): Likewise. Reset
10607 minimum length if maximum lengh is unknown.
10608 * gimple-ssa-sprintf.c (get_string_length): Likewise. Drop code
10609 that used c_strlen, it's no longer needed. Restructure slightly.
10610 (format_string): Set unlikely range appropriately.
10611 * gimple-fold.c (get_range_strlen): Update comments. Fix minor
10613 (get_range_strlen): Accept c_strlen_data pointer for external
10614 call sites as well. Pass through to call to internal get_range_strlen.
10615 Adjust minlen, maxlen and maxbound as needed.
10616 (get_maxval_strlen): Update comments.
10617 (gimple_fold_builtin_strlen): Update call to get_range_strlen
10618 to use c_strlen_data pointer. Change variable accesses to instead
10619 use c_strlen_data data members.
10621 * gimple-fold.c (get_range_strlen): Update prototype.
10622 (get_range_strlen_tree): Update prototype. Drop minlen/maxlen
10623 local variables. Use pdata to return information to caller.
10624 Update calls to get_range_strlen. Update pdata->maxbound.
10625 (get_range_strlen -- static version): Similarly.
10626 (get_range_strlen -- extern version): Update for internal
10627 get_range_strlen API change. Convert to external data format.
10628 (get_maxval_strlen): Similarly.
10630 2019-01-01 Jan Hubicka <hubicka@ucw.cz>
10632 * coverage.c (get_coverage_counts): Use current_function_decl.
10633 * profile.c (read_thunk_profile): New function.
10634 (branch_prob): Add THUNK parameter.
10635 * tree-profile.c (tree_profiling): Handle thunks.
10636 * value-prof.c (init_node_map): Handle thunks.
10637 * value-prof.h (branch_prob): Upate prototype.
10638 (read_thunk_profile): Declare.
10640 2019-01-01 Jakub Jelinek <jakub@redhat.com>
10642 Update copyright years.
10644 * gcc.c (process_command): Update copyright notice dates.
10645 * gcov-dump.c (print_version): Ditto.
10646 * gcov.c (print_version): Ditto.
10647 * gcov-tool.c (print_version): Ditto.
10648 * gengtype.c (create_file): Ditto.
10649 * doc/cpp.texi: Bump @copying's copyright year.
10650 * doc/cppinternals.texi: Ditto.
10651 * doc/gcc.texi: Ditto.
10652 * doc/gccint.texi: Ditto.
