10595
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.
10599
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
10612         formatting issues.
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.
10620
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.

10631
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.
