PR middle-end/88663
* gimple-fold.c (get_range_strlen): Update prototype to no longer
need the flexp argument.
(get_range_strlen_tree): Drop flexp argument. Drop flexp argument
from calls to get_range_strlen. Update comments. Just update
VAL for an unterminated const char array and let the reset of the
code handle it normally. No longer try to set *flexp. Adjust
return value.
(get_range_strlen): Update for the new get_range_strlen API.
(get_maxval_strlen): Similarly.
(gimple_fold_builtin_strlen): Handle update meaning of return value
from get_range_strlen.
* gimple-ssa-sprintf.c (get_string_length): Update for the new
get_range_strlen API.

PR lto/88130
* varpool.c (varpool_node::ctor_useable_for_folding_p): Also return
false at WPA time when body was removed.

PR tree-optimization/88650
* predict.c (set_even_probabilities): Calculate probability
remainer only when really used.
2019-01-02 Richard Biener <rguenther@suse.de>
PR middle-end/88651
* tree-data-ref.c (analyze_subscript_affine_affine): Use
widest_ints when mangling max_stmt_execution results.

PR tree-optimization/88621
* tree-ssa-loop-im.c (gather_mem_refs_stmt): Fix pastos, avoid
bitfields when canoncalizing.

PR target/87545
* config/i386/x86-tune-costs.h (intel_cost): Adjust
cost of cheap SSE instruction.

PR ipa/85574
* ipa-icf.h (sem_item_optimizer::sort_congruence_split): Declare.
* ipa-icf.c (sem_item_optimizer::sort_congruence_split): New
function.
(sem_item_optimizer::do_congruence_step_f): Sort the congruence
set after UIDs before splitting them.

* gimple-fold.c (get_range_strlen_tree): Record if the computed
length is optimistic. If it is, then arrange to compute the
conservative length as well.
* gimple-fold.h (get_range_strlen): Update prototype.
* builtins.c (check_access): Update call to get_range_strlen to use
c_strlen_data pointer. Change various variable accesses to instead
pull data from the c_strlen_data structure.
(check_strncat_sizes, expand_builtin_strncat): Likewise.
* calls.c (maybe_warn_nonstring_arg): Likewise.
* tree-ssa-strlen.c (maybe_diag_stxncpy_trunc): Likewise. Reset
minimum length if maximum lengh is unknown.
* gimple-ssa-sprintf.c (get_string_length): Likewise. Drop code
that used c_strlen, it's no longer needed. Restructure slightly.
(format_string): Set unlikely range appropriately.
* gimple-fold.c (get_range_strlen): Update comments. Fix minor
formatting issues.
(get_range_strlen): Accept c_strlen_data pointer for external
call sites as well. Pass through to call to internal get_range_strlen.
Adjust minlen, maxlen and maxbound as needed.
(get_maxval_strlen): Update comments.
(gimple_fold_builtin_strlen): Update call to get_range_strlen
to use c_strlen_data pointer. Change variable accesses to instead
use c_strlen_data data members.
* gimple-fold.c (get_range_strlen): Update prototype.
(get_range_strlen_tree): Update prototype. Drop minlen/maxlen
local variables. Use pdata to return information to caller.
Update calls to get_range_strlen. Update pdata->maxbound.
(get_range_strlen -- static version): Similarly.
(get_range_strlen -- extern version): Update for internal
get_range_strlen API change. Convert to external data format.
(get_maxval_strlen): Similarly.

* coverage.c (get_coverage_counts): Use current_function_decl.
* profile.c (read_thunk_profile): New function.
(branch_prob): Add THUNK parameter.
* tree-profile.c (tree_profiling): Handle thunks.
* value-prof.c (init_node_map): Handle thunks.
* value-prof.h (branch_prob): Upate prototype.
(read_thunk_profile): Declare.
