6011 * tree-ssa-loop-im.c (gather_mem_refs_stmt): Fix pastos, avoid
6012 bitfields when canoncalizing.

6017 * config/i386/x86-tune-costs.h (intel_cost): Adjust
6018 cost of cheap SSE instruction.

6032 * gimple-fold.c (get_range_strlen_tree): Record if the computed
6033 length is optimistic. If it is, then arrange to compute the
6034 conservative length as well.
6036 * gimple-fold.h (get_range_strlen): Update prototype.
6037 * builtins.c (check_access): Update call to get_range_strlen to use
6038 c_strlen_data pointer. Change various variable accesses to instead
6039 pull data from the c_strlen_data structure.
6040 (check_strncat_sizes, expand_builtin_strncat): Likewise.
6041 * calls.c (maybe_warn_nonstring_arg): Likewise.
6042 * tree-ssa-strlen.c (maybe_diag_stxncpy_trunc): Likewise. Reset
6043 minimum length if maximum lengh is unknown.
6044 * gimple-ssa-sprintf.c (get_string_length): Likewise. Drop code
6045 that used c_strlen, it's no longer needed. Restructure slightly.
6046 (format_string): Set unlikely range appropriately.
6047 * gimple-fold.c (get_range_strlen): Update comments. Fix minor
6049 (get_range_strlen): Accept c_strlen_data pointer for external
6050 call sites as well. Pass through to call to internal get_range_strlen.
6051 Adjust minlen, maxlen and maxbound as needed.
6052 (get_maxval_strlen): Update comments.
6053 (gimple_fold_builtin_strlen): Update call to get_range_strlen
6054 to use c_strlen_data pointer. Change variable accesses to instead
6055 use c_strlen_data data members.
6057 * gimple-fold.c (get_range_strlen): Update prototype.
6058 (get_range_strlen_tree): Update prototype. Drop minlen/maxlen
6059 local variables. Use pdata to return information to caller.
6060 Update calls to get_range_strlen. Update pdata->maxbound.
6061 (get_range_strlen -- static version): Similarly.
6062 (get_range_strlen -- extern version): Update for internal
6063 get_range_strlen API change. Convert to external data format.
6064 (get_maxval_strlen): Similarly.
