27077 * gimple-fold.c (get_range_strlen_tree): Record if the computed
27078 length is optimistic. If it is, then arrange to compute the
27079 conservative length as well.
27081 * gimple-fold.h (get_range_strlen): Update prototype.
27082 * builtins.c (check_access): Update call to get_range_strlen to use
27083 c_strlen_data pointer. Change various variable accesses to instead
27084 pull data from the c_strlen_data structure.
27085 (check_strncat_sizes, expand_builtin_strncat): Likewise.
27086 * calls.c (maybe_warn_nonstring_arg): Likewise.
27087 * tree-ssa-strlen.c (maybe_diag_stxncpy_trunc): Likewise. Reset
27088 minimum length if maximum lengh is unknown.
27089 * gimple-ssa-sprintf.c (get_string_length): Likewise. Drop code
27090 that used c_strlen, it's no longer needed. Restructure slightly.
27091 (format_string): Set unlikely range appropriately.
27092 * gimple-fold.c (get_range_strlen): Update comments. Fix minor
27094 (get_range_strlen): Accept c_strlen_data pointer for external
27095 call sites as well. Pass through to call to internal get_range_strlen.
27096 Adjust minlen, maxlen and maxbound as needed.
27097 (get_maxval_strlen): Update comments.
27098 (gimple_fold_builtin_strlen): Update call to get_range_strlen
27099 to use c_strlen_data pointer. Change variable accesses to instead
27100 use c_strlen_data data members.
27102 * gimple-fold.c (get_range_strlen): Update prototype.
27103 (get_range_strlen_tree): Update prototype. Drop minlen/maxlen
27104 local variables. Use pdata to return information to caller.
27105 Update calls to get_range_strlen. Update pdata->maxbound.
27106 (get_range_strlen -- static version): Similarly.
27107 (get_range_strlen -- extern version): Update for internal
27108 get_range_strlen API change. Convert to external data format.
27109 (get_maxval_strlen): Similarly.
27111 2019-01-01 Jan Hubicka <hubicka@ucw.cz>
27113 * coverage.c (get_coverage_counts): Use current_function_decl.
27114 * profile.c (read_thunk_profile): New function.
27115 (branch_prob): Add THUNK parameter.
27116 * tree-profile.c (tree_profiling): Handle thunks.
27117 * value-prof.c (init_node_map): Handle thunks.
27118 * value-prof.h (branch_prob): Upate prototype.
27119 (read_thunk_profile): Declare.
