  24         (expand_omp_for_generic, expand_omp_for_static_nochunk,
  25         expand_omp_for_static_chunk, expand_omp_for): Use
  26         fd->have_pointer_condtemp instead of fd->lastprivate_conditional to
  27         determine if a special set of API routines are needed and if condtemp
  28         needs to be initialized, while always initialize cond_var if
  29         fd->lastprivate_conditional is non-zero.

9996
9997         * gimple-fold.c (get_range_strlen_tree): Record if the computed
9998         length is optimistic.  If it is, then arrange to compute the
9999         conservative length as well.
10000
10001         * gimple-fold.h (get_range_strlen): Update prototype.
10002         * builtins.c (check_access): Update call to get_range_strlen to use
10003         c_strlen_data pointer.   Change various variable accesses to instead
10004         pull data from the c_strlen_data structure.
10005         (check_strncat_sizes, expand_builtin_strncat): Likewise.
10006         * calls.c (maybe_warn_nonstring_arg): Likewise.
10007         * tree-ssa-strlen.c (maybe_diag_stxncpy_trunc): Likewise.  Reset
10008         minimum length if maximum lengh is unknown.
10009         * gimple-ssa-sprintf.c (get_string_length): Likewise.  Drop code
10010         that used c_strlen, it's no longer needed.  Restructure slightly.
10011         (format_string): Set unlikely range appropriately.
10012         * gimple-fold.c (get_range_strlen): Update comments.  Fix minor
10013         formatting issues.
10014         (get_range_strlen):  Accept c_strlen_data pointer for external
10015         call sites as well.  Pass through to call to internal get_range_strlen.
10016         Adjust minlen, maxlen and maxbound as needed.
10017         (get_maxval_strlen): Update comments.
10018         (gimple_fold_builtin_strlen):  Update call to get_range_strlen
10019         to use c_strlen_data pointer.  Change variable accesses to instead
10020         use c_strlen_data data members.
10021
10022         * gimple-fold.c (get_range_strlen): Update prototype.
10023         (get_range_strlen_tree): Update prototype.  Drop minlen/maxlen
10024         local variables.  Use pdata to return information to caller.
10025         Update calls to get_range_strlen.  Update pdata->maxbound.
10026         (get_range_strlen -- static version): Similarly.
10027         (get_range_strlen -- extern version): Update for internal
10028         get_range_strlen API change.  Convert to external data format.
10029         (get_maxval_strlen): Similarly.

10032
10033         * coverage.c (get_coverage_counts): Use current_function_decl.
10034         * profile.c (read_thunk_profile): New function.
10035         (branch_prob): Add THUNK parameter.
10036         * tree-profile.c (tree_profiling): Handle thunks.
10037         * value-prof.c (init_node_map): Handle thunks.
10038         * value-prof.h (branch_prob): Upate prototype.
10039         (read_thunk_profile): Declare.
