6252         * gimple-fold.c (get_range_strlen_tree): Record if the computed
6253         length is optimistic.  If it is, then arrange to compute the
6254         conservative length as well.
6255
6256         * gimple-fold.h (get_range_strlen): Update prototype.
6257         * builtins.c (check_access): Update call to get_range_strlen to use
6258         c_strlen_data pointer.   Change various variable accesses to instead
6259         pull data from the c_strlen_data structure.
6260         (check_strncat_sizes, expand_builtin_strncat): Likewise.
6261         * calls.c (maybe_warn_nonstring_arg): Likewise.
6262         * tree-ssa-strlen.c (maybe_diag_stxncpy_trunc): Likewise.  Reset
6263         minimum length if maximum lengh is unknown.
6264         * gimple-ssa-sprintf.c (get_string_length): Likewise.  Drop code
6265         that used c_strlen, it's no longer needed.  Restructure slightly.
6266         (format_string): Set unlikely range appropriately.
6267         * gimple-fold.c (get_range_strlen): Update comments.  Fix minor
6268         formatting issues.
6269         (get_range_strlen):  Accept c_strlen_data pointer for external
6270         call sites as well.  Pass through to call to internal get_range_strlen.
6271         Adjust minlen, maxlen and maxbound as needed.
6272         (get_maxval_strlen): Update comments.
6273         (gimple_fold_builtin_strlen):  Update call to get_range_strlen
6274         to use c_strlen_data pointer.  Change variable accesses to instead
6275         use c_strlen_data data members.
6276
6277         * gimple-fold.c (get_range_strlen): Update prototype.
6278         (get_range_strlen_tree): Update prototype.  Drop minlen/maxlen
6279         local variables.  Use pdata to return information to caller.
6280         Update calls to get_range_strlen.  Update pdata->maxbound.
6281         (get_range_strlen -- static version): Similarly.
6282         (get_range_strlen -- extern version): Update for internal
6283         get_range_strlen API change.  Convert to external data format.
6284         (get_maxval_strlen): Similarly.

6287
6288         * coverage.c (get_coverage_counts): Use current_function_decl.
6289         * profile.c (read_thunk_profile): New function.
6290         (branch_prob): Add THUNK parameter.
6291         * tree-profile.c (tree_profiling): Handle thunks.
6292         * value-prof.c (init_node_map): Handle thunks.
6293         * value-prof.h (branch_prob): Upate prototype.
6294         (read_thunk_profile): Declare.
