5922         (sem_item_optimizer::do_congruence_step_f): Sort the congruence
5923         set after UIDs before splitting them.

5927
5928         * gimple-fold.c (get_range_strlen_tree): Record if the computed
5929         length is optimistic.  If it is, then arrange to compute the
5930         conservative length as well.
5931
5932         * gimple-fold.h (get_range_strlen): Update prototype.
5933         * builtins.c (check_access): Update call to get_range_strlen to use
5934         c_strlen_data pointer.   Change various variable accesses to instead
5935         pull data from the c_strlen_data structure.
5936         (check_strncat_sizes, expand_builtin_strncat): Likewise.
5937         * calls.c (maybe_warn_nonstring_arg): Likewise.
5938         * tree-ssa-strlen.c (maybe_diag_stxncpy_trunc): Likewise.  Reset
5939         minimum length if maximum lengh is unknown.
5940         * gimple-ssa-sprintf.c (get_string_length): Likewise.  Drop code
5941         that used c_strlen, it's no longer needed.  Restructure slightly.
5942         (format_string): Set unlikely range appropriately.
5943         * gimple-fold.c (get_range_strlen): Update comments.  Fix minor
5944         formatting issues.
5945         (get_range_strlen):  Accept c_strlen_data pointer for external
5946         call sites as well.  Pass through to call to internal get_range_strlen.
5947         Adjust minlen, maxlen and maxbound as needed.
5948         (get_maxval_strlen): Update comments.
5949         (gimple_fold_builtin_strlen):  Update call to get_range_strlen
5950         to use c_strlen_data pointer.  Change variable accesses to instead
5951         use c_strlen_data data members.
5952
5953         * gimple-fold.c (get_range_strlen): Update prototype.
5954         (get_range_strlen_tree): Update prototype.  Drop minlen/maxlen
5955         local variables.  Use pdata to return information to caller.
5956         Update calls to get_range_strlen.  Update pdata->maxbound.
5957         (get_range_strlen -- static version): Similarly.
5958         (get_range_strlen -- extern version): Update for internal
5959         get_range_strlen API change.  Convert to external data format.
5960         (get_maxval_strlen): Similarly.

5964         * coverage.c (get_coverage_counts): Use current_function_decl.
5965         * profile.c (read_thunk_profile): New function.
5966         (branch_prob): Add THUNK parameter.
5967         * tree-profile.c (tree_profiling): Handle thunks.
5968         * value-prof.c (init_node_map): Handle thunks.
5969         * value-prof.h (branch_prob): Upate prototype.
5970         (read_thunk_profile): Declare.
