7043 minimum length if maximum lengh is unknown.
7044 * gimple-ssa-sprintf.c (get_string_length): Likewise. Drop code
7045 that used c_strlen, it's no longer needed. Restructure slightly.
7046 (format_string): Set unlikely range appropriately.
7047 * gimple-fold.c (get_range_strlen): Update comments. Fix minor
7049 (get_range_strlen): Accept c_strlen_data pointer for external
7050 call sites as well. Pass through to call to internal get_range_strlen.
7051 Adjust minlen, maxlen and maxbound as needed.
7052 (get_maxval_strlen): Update comments.
7053 (gimple_fold_builtin_strlen): Update call to get_range_strlen
7054 to use c_strlen_data pointer. Change variable accesses to instead
7055 use c_strlen_data data members.
7057 * gimple-fold.c (get_range_strlen): Update prototype.
7058 (get_range_strlen_tree): Update prototype. Drop minlen/maxlen
7059 local variables. Use pdata to return information to caller.
7060 Update calls to get_range_strlen. Update pdata->maxbound.
7061 (get_range_strlen -- static version): Similarly.
7062 (get_range_strlen -- extern version): Update for internal
7063 get_range_strlen API change. Convert to external data format.
7064 (get_maxval_strlen): Similarly.

7069 * profile.c (read_thunk_profile): New function.
7070 (branch_prob): Add THUNK parameter.
7071 * tree-profile.c (tree_profiling): Handle thunks.
