11054 set after UIDs before splitting them.

11059 * gimple-fold.c (get_range_strlen_tree): Record if the computed
11060 length is optimistic. If it is, then arrange to compute the
11061 conservative length as well.
11063 * gimple-fold.h (get_range_strlen): Update prototype.
11064 * builtins.c (check_access): Update call to get_range_strlen to use
11065 c_strlen_data pointer. Change various variable accesses to instead
11066 pull data from the c_strlen_data structure.
11067 (check_strncat_sizes, expand_builtin_strncat): Likewise.
11068 * calls.c (maybe_warn_nonstring_arg): Likewise.
11069 * tree-ssa-strlen.c (maybe_diag_stxncpy_trunc): Likewise. Reset
11070 minimum length if maximum lengh is unknown.
11071 * gimple-ssa-sprintf.c (get_string_length): Likewise. Drop code
11072 that used c_strlen, it's no longer needed. Restructure slightly.
11073 (format_string): Set unlikely range appropriately.
11074 * gimple-fold.c (get_range_strlen): Update comments. Fix minor
11076 (get_range_strlen): Accept c_strlen_data pointer for external
11077 call sites as well. Pass through to call to internal get_range_strlen.
11078 Adjust minlen, maxlen and maxbound as needed.
11079 (get_maxval_strlen): Update comments.
11080 (gimple_fold_builtin_strlen): Update call to get_range_strlen
11081 to use c_strlen_data pointer. Change variable accesses to instead
11082 use c_strlen_data data members.
11084 * gimple-fold.c (get_range_strlen): Update prototype.
11085 (get_range_strlen_tree): Update prototype. Drop minlen/maxlen
11086 local variables. Use pdata to return information to caller.
11087 Update calls to get_range_strlen. Update pdata->maxbound.
11088 (get_range_strlen -- static version): Similarly.
11089 (get_range_strlen -- extern version): Update for internal
11090 get_range_strlen API change. Convert to external data format.
11091 (get_maxval_strlen): Similarly.
11093 2019-01-01 Jan Hubicka <hubicka@ucw.cz>
11095 * coverage.c (get_coverage_counts): Use current_function_decl.
11096 * profile.c (read_thunk_profile): New function.
11097 (branch_prob): Add THUNK parameter.
11098 * tree-profile.c (tree_profiling): Handle thunks.
11099 * value-prof.c (init_node_map): Handle thunks.
11100 * value-prof.h (branch_prob): Upate prototype.
11101 (read_thunk_profile): Declare.
