5872 (aarch64_emit_cfi_for_reg_p): New function.
5873 (aarch64_reg_save_mode): Remove the fndecl argument and instead use
5874 crtl->abi to choose the mode for FP registers. Handle the SVE PCS.
5875 (aarch64_hard_regno_call_part_clobbered): Do not treat FP registers
5876 as partly clobbered for the SVE PCS.
5877 (aarch64_function_ok_for_sibcall): Check whether the two functions
5878 use the same ABI, rather than checking specifically for whether
5879 they're aarch64_vector_pcs functions.
5880 (aarch64_pass_by_reference): Raise an error for attempts to pass
5881 SVE arguments when SVE is disabled. Pass SVE arguments by reference
5882 if there are not enough free registers left, or if the argument is
5884 (aarch64_function_value): Handle SVE predicates, vectors and tuples.
5885 (aarch64_return_in_memory): Do not return SVE predicates, vectors and
5887 (aarch64_layout_arg): Take a function_arg_info rather than
5888 individual properties. Handle SVE predicates, vectors and tuples.
5889 Raise an error if they are passed to unprototyped functions.
5890 (aarch64_function_arg): If the silent_p flag is set, suppress the
5891 usual error about using float registers without TARGET_FLOAT.
5892 (aarch64_init_cumulative_args): Take a silent_p parameter and store
5893 it in the cumulative_args structure. Initialize aapcs_nprn and
5894 aapcs_nextnprn. If the silent_p flag is set, suppress the usual
5895 error about using float registers without TARGET_FLOAT.
5896 If the silent_p flag is not set, also raise an error about
5897 using SVE functions when SVE is disabled.
5898 (aarch64_function_arg_advance): Update the call to aarch64_layout_arg,
5899 and call it for SVE functions too. Update aapcs_nprn similarly
5900 to the other register counts.
5901 (aarch64_layout_frame): If a big-endian function needs to save
5902 and restore Z8-Z15, search for a spare predicate that it can use.
5903 Store SVE predicates at the bottom of the register save area,
5904 followed by SVE vectors, then followed by the normal slots.
5905 Keep pointing the hard frame pointer at the base of the normal slots,
5906 above the SVE vectors. Update the various frame creation and
5907 tear-down strategies for the new layout, initializing the new
5908 sve_callee_adjust field. Add an additional layout for frames
5909 whose saved registers are all SVE registers.
5910 (aarch64_register_saved_on_entry): Cope with poly_int64 reg_offsets.
5911 (aarch64_return_address_signing_enabled): Likewise.
5912 (aarch64_push_regs, aarch64_pop_regs): Update calls to
5913 aarch64_reg_save_mode.
5914 (aarch64_adjust_sve_callee_save_base): New function.
5915 (aarch64_add_cfa_expression): Move earlier in file. Take the
5916 saved register as an rtx rather than a register number and use
5917 its mode for the MEM slot.
5918 (aarch64_save_callee_saves): Remove the mode argument and instead
5919 use aarch64_reg_save_mode to get the mode of each save slot.
5920 Add a hard_fp_valid_p parameter. Cope with poly_int64 register
5921 offsets. Allow GP offsets to be saved at a VL-based offset from
5922 the stack, handling this case using the frame pointer if available
5923 or a temporary register otherwise. Use ST1D to save Z8-Z15 for
5924 big-endian SVE functions; use normal moves for other SVE saves.
5925 Only mark the save as frame-related if aarch64_emit_cfi_for_reg_p
5926 returns true. Add explicit CFA notes when not storing via the
5927 stack pointer. Do not try to pair SVE saves.
5928 (aarch64_restore_callee_saves): Cope with poly_int64 register
5929 offsets. Use LD1D to restore Z8-Z15 for big-endian SVE functions;
5930 use normal moves for other SVE restores. Only add CFA restore notes
5931 if aarch64_emit_cfi_for_reg_p returns true. Do not try to pair
5933 (aarch64_get_separate_components): Always keep the first SVE save
5934 in the prologue if we need to use it as a stack probe. Don't allow
5935 Z8-Z15 saves and loads to be shrink-wrapped for big-endian targets.
5936 Likewise the spare predicate register that they need. Update the
5937 offset calculation to account for the SVE save area. Use the
5938 appropriate range check for SVE LDR and STR instructions.
5939 (aarch64_components_for_bb): Cope with poly_int64 reg_offsets.
5940 (aarch64_process_components): Likewise. Update the offset
5941 calculation to account for the SVE save area. Only mark the
5942 save as frame-related if aarch64_emit_cfi_for_reg_p returns true.
5943 Do not try to pair SVE saves.
5944 (aarch64_allocate_and_probe_stack_space): Cope with poly_int64
5945 reg_offsets. When handling the final allocation, expect the
5946 first SVE register save to be part of the initial allocation
5947 and for it to act as a probe at SP. Account for the SVE callee
5948 save area in the dump information.
5949 (aarch64_expand_prologue): Update the frame diagram. Fold the
5950 SVE callee allocation into the initial allocation if stack clash
5951 protection is enabled. Use new variables to track the offset
5952 of the frame chain (and hard frame pointer) from the current
5953 stack pointer, and likewise the offset of the bottom of the
5954 register save area. Update calls to aarch64_save_callee_saves
5955 and aarch64_add_cfa_expression. Apply sve_callee_adjust before
5956 saving the FP&SIMD registers. Save the predicate registers.
5957 (aarch64_expand_epilogue): Take below_hard_fp_saved_regs_size
5958 into account when setting the stack pointer from the frame pointer,
5959 and when deciding whether we can inherit the initial adjustment
5960 amount from the prologue. Restore the predicate registers after
5961 the vector registers, then apply sve_callee_adjust, then restore
5962 the general registers.
5963 (aarch64_secondary_reload): Don't use secondary SVE reloads
5965 (aapcs_vfp_sub_candidate): Assert that the type is not an SVE type.
5966 (aarch64_short_vector_p): Return false for SVE types.
5967 (aarch64_vfp_is_call_or_return_candidate): Initialize *is_ha
5968 at the start of the function. Return false for SVE types.

34882 * config/i386/x86-tune-costs.h (intel_cost): Adjust
34883 cost of cheap SSE instruction.
34885 2019-01-02 Richard Biener <rguenther@suse.de>
34888 * ipa-icf.h (sem_item_optimizer::sort_congruence_split): Declare.
34889 * ipa-icf.c (sem_item_optimizer::sort_congruence_split): New
34891 (sem_item_optimizer::do_congruence_step_f): Sort the congruence
34892 set after UIDs before splitting them.
34894 2019-01-01 Martin Sebor <msebor@redhat.com>
34895 Jeff Law <law@redhat.com>
34897 * gimple-fold.c (get_range_strlen_tree): Record if the computed
34898 length is optimistic. If it is, then arrange to compute the
34899 conservative length as well.
34901 * gimple-fold.h (get_range_strlen): Update prototype.
34902 * builtins.c (check_access): Update call to get_range_strlen to use
34903 c_strlen_data pointer. Change various variable accesses to instead
34904 pull data from the c_strlen_data structure.
34905 (check_strncat_sizes, expand_builtin_strncat): Likewise.
34906 * calls.c (maybe_warn_nonstring_arg): Likewise.
34907 * tree-ssa-strlen.c (maybe_diag_stxncpy_trunc): Likewise. Reset
34908 minimum length if maximum lengh is unknown.
34909 * gimple-ssa-sprintf.c (get_string_length): Likewise. Drop code
34910 that used c_strlen, it's no longer needed. Restructure slightly.
34911 (format_string): Set unlikely range appropriately.
34912 * gimple-fold.c (get_range_strlen): Update comments. Fix minor
34914 (get_range_strlen): Accept c_strlen_data pointer for external
34915 call sites as well. Pass through to call to internal get_range_strlen.
34916 Adjust minlen, maxlen and maxbound as needed.
34917 (get_maxval_strlen): Update comments.
34918 (gimple_fold_builtin_strlen): Update call to get_range_strlen
34919 to use c_strlen_data pointer. Change variable accesses to instead
34920 use c_strlen_data data members.
34922 * gimple-fold.c (get_range_strlen): Update prototype.
34923 (get_range_strlen_tree): Update prototype. Drop minlen/maxlen
34924 local variables. Use pdata to return information to caller.
34925 Update calls to get_range_strlen. Update pdata->maxbound.
34926 (get_range_strlen -- static version): Similarly.
34927 (get_range_strlen -- extern version): Update for internal
34928 get_range_strlen API change. Convert to external data format.
34929 (get_maxval_strlen): Similarly.
34931 2019-01-01 Jan Hubicka <hubicka@ucw.cz>
34933 * coverage.c (get_coverage_counts): Use current_function_decl.
34934 * profile.c (read_thunk_profile): New function.
34935 (branch_prob): Add THUNK parameter.
34936 * tree-profile.c (tree_profiling): Handle thunks.
34937 * value-prof.c (init_node_map): Handle thunks.
34938 * value-prof.h (branch_prob): Upate prototype.
34939 (read_thunk_profile): Declare.
34941 2019-01-01 Jakub Jelinek <jakub@redhat.com>
34943 Update copyright years.
34945 * gcc.c (process_command): Update copyright notice dates.
34946 * gcov-dump.c (print_version): Ditto.
34947 * gcov.c (print_version): Ditto.
34948 * gcov-tool.c (print_version): Ditto.
34949 * gengtype.c (create_file): Ditto.
34950 * doc/cpp.texi: Bump @copying's copyright year.
34951 * doc/cppinternals.texi: Ditto.
34952 * doc/gcc.texi: Ditto.
34953 * doc/gccint.texi: Ditto.
