10188 * gimple-fold.c (get_range_strlen_tree): Record if the computed
10189 length is optimistic. If it is, then arrange to compute the
10190 conservative length as well.
10192 * gimple-fold.h (get_range_strlen): Update prototype.
10193 * builtins.c (check_access): Update call to get_range_strlen to use
10194 c_strlen_data pointer. Change various variable accesses to instead
10195 pull data from the c_strlen_data structure.
10196 (check_strncat_sizes, expand_builtin_strncat): Likewise.
10197 * calls.c (maybe_warn_nonstring_arg): Likewise.
10198 * tree-ssa-strlen.c (maybe_diag_stxncpy_trunc): Likewise. Reset
10199 minimum length if maximum lengh is unknown.
10200 * gimple-ssa-sprintf.c (get_string_length): Likewise. Drop code
10201 that used c_strlen, it's no longer needed. Restructure slightly.
10202 (format_string): Set unlikely range appropriately.
10203 * gimple-fold.c (get_range_strlen): Update comments. Fix minor
10205 (get_range_strlen): Accept c_strlen_data pointer for external
10206 call sites as well. Pass through to call to internal get_range_strlen.
10207 Adjust minlen, maxlen and maxbound as needed.
10208 (get_maxval_strlen): Update comments.
10209 (gimple_fold_builtin_strlen): Update call to get_range_strlen
10210 to use c_strlen_data pointer. Change variable accesses to instead
10211 use c_strlen_data data members.
10213 * gimple-fold.c (get_range_strlen): Update prototype.
10214 (get_range_strlen_tree): Update prototype. Drop minlen/maxlen
10215 local variables. Use pdata to return information to caller.
10216 Update calls to get_range_strlen. Update pdata->maxbound.
10217 (get_range_strlen -- static version): Similarly.
10218 (get_range_strlen -- extern version): Update for internal
10219 get_range_strlen API change. Convert to external data format.
10220 (get_maxval_strlen): Similarly.
10222 2019-01-01 Jan Hubicka <hubicka@ucw.cz>
10224 * coverage.c (get_coverage_counts): Use current_function_decl.
10225 * profile.c (read_thunk_profile): New function.
10226 (branch_prob): Add THUNK parameter.
10227 * tree-profile.c (tree_profiling): Handle thunks.
10228 * value-prof.c (init_node_map): Handle thunks.
10229 * value-prof.h (branch_prob): Upate prototype.
10230 (read_thunk_profile): Declare.
