6520 * gimple-fold.c (get_range_strlen_tree): Record if the computed
6521 length is optimistic. If it is, then arrange to compute the
6522 conservative length as well.
6524 * gimple-fold.h (get_range_strlen): Update prototype.
6525 * builtins.c (check_access): Update call to get_range_strlen to use
6526 c_strlen_data pointer. Change various variable accesses to instead
6527 pull data from the c_strlen_data structure.
6528 (check_strncat_sizes, expand_builtin_strncat): Likewise.
6529 * calls.c (maybe_warn_nonstring_arg): Likewise.
6530 * tree-ssa-strlen.c (maybe_diag_stxncpy_trunc): Likewise. Reset
6531 minimum length if maximum lengh is unknown.
6532 * gimple-ssa-sprintf.c (get_string_length): Likewise. Drop code
6533 that used c_strlen, it's no longer needed. Restructure slightly.
6534 (format_string): Set unlikely range appropriately.
6535 * gimple-fold.c (get_range_strlen): Update comments. Fix minor
6537 (get_range_strlen): Accept c_strlen_data pointer for external
6538 call sites as well. Pass through to call to internal get_range_strlen.
6539 Adjust minlen, maxlen and maxbound as needed.
6540 (get_maxval_strlen): Update comments.
6541 (gimple_fold_builtin_strlen): Update call to get_range_strlen
6542 to use c_strlen_data pointer. Change variable accesses to instead
6543 use c_strlen_data data members.
6545 * gimple-fold.c (get_range_strlen): Update prototype.
6546 (get_range_strlen_tree): Update prototype. Drop minlen/maxlen
6547 local variables. Use pdata to return information to caller.
6548 Update calls to get_range_strlen. Update pdata->maxbound.
6549 (get_range_strlen -- static version): Similarly.
6550 (get_range_strlen -- extern version): Update for internal
6551 get_range_strlen API change. Convert to external data format.
6552 (get_maxval_strlen): Similarly.
6554 2019-01-01 Jan Hubicka <hubicka@ucw.cz>
6556 * coverage.c (get_coverage_counts): Use current_function_decl.
6557 * profile.c (read_thunk_profile): New function.
6558 (branch_prob): Add THUNK parameter.
6559 * tree-profile.c (tree_profiling): Handle thunks.
6560 * value-prof.c (init_node_map): Handle thunks.
6561 * value-prof.h (branch_prob): Upate prototype.
6562 (read_thunk_profile): Declare.
